Weâre looking for people who understand how to apply cryptography to problems. While understanding the mathematical backgrounds to cryptography is great, itâs not essential if you understand how the cryptographic primitives like hashing and message signing work together to solve real problems. We value passion and hard work when tackling challenges and above all else although an interest in arts and collectibles is helpful.

About Cuvva
Cuvva is making car insurance radically better.
Weâre creating truly flexible products that meet peopleâs real needs. Using lightning-fast technology to unlock better experiences and fairer prices for our customers, Cuvva is building the future of insurance every day.
Cuvva was the first UK company to sell hourly insurance through an app. Since then weâve sold over 3 million policies and supported over 450,000 customers. Weâre a world-class team of over 100 people, passionate about solving our customersâ problems. Join us.
Why work for Cuvva?
We donât cut corners. We strive to do the right thing, even when that makes life more difficult for us.
We are customer centric and everyone in every area of the businessâincluding our CEO & Founder Freddyâis expected to spend a few hours a month on customer support. This is so we all fully understand customer needs and how the app works! Hereâs a blog post on our âCops Clubâ.
Weâve nurtured an awesome team culture. We always speak up when we have an idea - but also know when to let go and get behind something else.
And weâre comfortable giving and receiving honest feedback, and trying new ways of doing things.
Weâre building a diverse team from different backgrounds, outlooks and experiences. Everyone is given a fair chance of getting a role at Cuvva. Even if you secretly donât love insurance, trust us, youâll love what weâre building.
About the role
Youâll work in one of our cross-functional product squads, helping the team achieve their goals - whether thatâs building a new service in our backend platform, creating a new version of an existing API to deliver a new feature, or creating a CLI tool to automate something.
We work in a highly collaborative fashion, and maintain an open and transparent work environment. Engineers at Cuvva donât just write code or implement against a spec. Youâll be expected and encouraged to take part in the entire product development process from problem-discovery to solution design, to implementation and rollout.
Each product squad autonomously owns an area of the Cuvva product. Squads are made up of engineers from multiple disciplines (backend, web, iOS, Android), product and content designers, and a product manager. Engineers at Cuvva come from a variety of backgrounds and have different but complementary skill sets. We donât require a computer science degree - many of us are self-taught.
Our approach
We value consistently-written, simple, resilient systems. Our backend is made up of many standalone services with a JSON-based RPC interface. We aim to create a client-agnostic API design suitable for a variety of clients (mobile apps, website, internal tooling, 3rd parties). Because weâre a regulated financial company, we have interesting and rigorous requirements to meet with regards to data security and auditability.
Most systems are written in Go (some older ones are Javascript), backed by either Postgres or Mongo, and are hosted in a container environment. We heavily lean on AWS tooling such as S3, Lambda, and SQS, and we occasionally build integrations with more âlegacyâ 3rd party systems in the insurance industry.
You can find out more about our backend systems here:
Our libraries and Go tooling is open sourced on GitHub
âShowing off our K-sortable IDsâ our blog
âHow we analyse and test new pricing modelsâ our blog
âHow we test and roll out new product featuresâ our blog
You'll do great here if you:
⢠Have genuine interest and curiosity about the Cuvva product, and consumer insurance in general
⢠Enjoy working as a team to solve problems collaboratively
⢠Have around 5 years of experience building rock-solid backend systems and APIs
⢠Have a track record of shipping great quality code with real customer impact
⢠Be comfortable and productive working with Go
â˘Â We donât require commercial Go experience but you would be expected to have a basic understanding and a willingness to learn
⢠Having a background with at least one statically-typed language is a good sign
â˘Â Know your way around the major AWS services (or similar cloud services), and have an enthusiasm for cloud services in general
â˘Â Be comfortable working with containers (e.g. Docker, K8S, ECR, container based CI platforms)
Perks & Benefits
Benefits
As well as a competitive salary (ÂŁ75-90k, dependent on experience) and equity based remuneration, benefits of working at Cuvva include:
⢠Brand new MacBook đť
⢠33 days holiday (inc public holidaysđ)
⢠Flexible working
⢠Wellbeing, personal development and work from home budgets
⢠Yearly increases to budgets and holiday allowances
⢠Generous parental leave policy
⢠One-to-one sessions with our Sanctus mental health coaches, giving you a safe space to talk đ§
⢠Access to Lifeworks - our mental health tool and employee assistance programme
⢠Mates rates on your car insurance
⢠Salary sacrifice schemes for electric bike hire and electric car lease
⢠Cycle to work scheme đ˛
⢠Season ticket loans đ
⢠A volunteer day
⢠Office library full of great books đ
⢠Great coffee machine in the office âď¸
⢠Fully stocked beer and soft drink fridge (we do team drinks every Thursday)

Monzoâs security team has a wide range of responsibilities, from infrastructure security to application security. As a bank, we are solving diverse, novel problems to ensure that our customers are safe and secure.
One of the guiding principles of security at Monzo is that security at the expense of user experience is a last resort. We aim to move mountains in the background such that we can build world-class features without compromising on security.
As a member of our security team you would be responsible for constantly improving the security of Monzo, and you would work closely with other teams to ensure that our systems are secure by design. Of course, security incidents can and do occur, and the security team is involved with many different types of incident response.
Our engineers have a variety of different backgrounds
We have several non-graduates; only some of us studied Computer Science; one of the team has a degree in Marketing; some of us have worked in huge companies; some have only ever worked in startups; others are former consultants. As long as you enjoy learning new things, weâd love to talk to you.
We encourage an open and transparent working environment
You can get involved in any aspect of the business you are interested in and, following Stripeâs example, all emails in the company are visible in an email archive. We regularly run hackathons in which people build things on our third party API and we contribute to open source software as much as possible. Weâve also made our product roadmap public and give sneak peeks of features in our community forum.

We rely heavily on the following tools and technologies:
Go to write our application code (thereâs an excellent interactive Go tutorial here)
Cassandra for most persistent data storage
Kafka for our asynchronous message queue
Linkerd/Finagle for RPC
Kubernetes and Docker to schedule and run our services (Oliver, our Head of Engineering, gave a great talk at KubeCon on how we use these technologies)

React for internal web dashboards
We also have two physical datacenter sites with actual cables to connect to various third parties

We can help you relocate to London, we can sponsor visas, and we're open to distributed working (as long as you can spend around 20% of your time in London).
We have payroll set up in five countries: the UK, Ireland, France, Poland and Spain. Right now, we can only hire people who work from those countries and weâll keep this updated with new ones as we expand and are able to hire from more places đ
We offer competitive salaries based on skills and experience, which could be anywhere between ÂŁ40,000 - ÂŁ100,000 per year.
We care deeply about inclusive working practices and diverse teams. If youâd prefer to work part-time or as a job-share, weâll try our best to make this happen. Just let us know in your application so we can plan for it.
We're usually always hiring for Backend Engineers in Security, so there's no closing date for this job.
Our interview process is normally a phone interview, a coding task and call to discuss it, and 2-3 hours of onsite interviews. We promise not to ask you any brain teasers or trick questions.

Job Description
Popsa is a design-led, engineering focussed company that uses machine learning to help people rediscover their best experiences and turn them into beautiful printed products.
We grew about 500% in 2018 and weâre now shipping over half a million photos a week to 50 countries around the world.
This position is a great opportunity for experienced software engineers with a background in the likes of Go, Python, PHP or Node.js looking to apply their existing skillset and learn and use Go in a production environment.

Weâre entirely hosted on AWS and make extensive use of many of their services (over 30 at last count!)
15+ containerised microservices running in ECS (weâre open to exploring moving to Kubernetes in the future if appropriate). Our services talk protocol buffers over HTTP and are discovered with Consul.
Dozens of event driven serverless functions running on Lambda, some running as APIs behind API Gateway and others as Step Functions
Dockerised batch compute workflows
NoSQL databases (predominantly DynamoDB and ElasticSearch)
Serverless analytics data lake backed by S3 using Athena (PrestoDB)
Terraform and Serverless Framework to manage our infrastructure as code

Our Head of Engineering Alex likes to describe our platform as an iceberg - the bit customers encounter is just the tip above the water - underneath is a dynamic event-driven structure that enables us to be a lean business that can iterate and experiment rapidly.
You will gain a unique perspective of a high growth business and have an opportunity to shape the landscape of our backend APIs, data pipelines and strategies, infrastructure automation and many more engineering goals.

Youâre keen to learn more about and play around with new technologies
What weâre doing here at Popsa excites you!
Desired skill set:
Strong competency with a language such as Go or Python; the majority of the Platform backend is written in Go, but weâre flexible and you'll have the opportunity to learn on the job as well as making use of your existing skillset.
You structure code for scalability, performance and testing
Experience writing and consuming RESTful and RPC APIs; you'll be designing and building new APIs for our mobile and web clients and integrating with new partners and suppliers
You know and appreciate automated testing

Job Description
Risk Ledger is seeking software engineers to join our core team and take ownership of developing & shaping our platform that sits on the intersection of cybersecurity and risk management. This is an opportunity to work with the latest technologies to solve an increasingly important problem, and to have an outsized impact on a product early in its lifecycle.
We are looking for an amazing and talented team from a diverse set of backgrounds and skillsets to help us grow and build a truly special company, from scratch. The main focus of the role will be on backend development, but to excel you should be comfortable up and down the stack - itâs all hands on deck at this stage, so youâll need to be ready and willing to delve into the front-end, ship new functionality, and be involved in the product development, improving and learning as we go.
What youâll be doing:
Building our systemâs backend, primarily in Go. If youâre a fast learner and keen to work with Go in production, weâd love to speak with you;
Developing and fleshing out our API. Weâll be ingesting a lot of data from our clients and their supply chain, so having a robust API is key to taking the stress out of our customersâ lives;
Getting your code, and that of the team, into production - hopefully continuously and bug-free!
Helping to expose the backend functionality in the frontend when necessary. The UI is built in HTML, CSS and JavaScript using Vue.js, so you should be confident enough to understand how everything fits together and be happy to make improvements where appropriate.
Working closely with the customer relations side of the company, to ensure that weâre always focused on and building what is right for our clients to make their lives easier, not just ours.
What success will look like:
An awesome looking product, with the functionality our clients need.
A growing engineering team that people enjoy working with, who laugh together, know each otherâs strengths and get the job done.
A rapidly expanding customer-base who are eager to use our product, keeping us on our toes when it comes to infrastructure and scaling.
Perks & Benefits
The autonomy and flexibility you need to deliver the work as you see fit.
The opportunity to get involved with, shape and lead the entire process of product strategy, design and implementation.
The equipment you need to get the job done.
All the learning resources and books you want to aid in your personal development.
Generous EMI stock options.
32 days of holiday a year - take a break, enjoy yourself!
Up to an additional 30 days of unpaid leave a year to use as you wish.

Job Description
At Geckoboard we help businesses use their data to align their teams on the metrics that matter most to them. Weâve been busy reimagining the way our customers get their data in Geckoboard and have a lot of interesting and creative work to do to shape their experiences. Right now, weâre looking for curious problem solvers to help us on this journey.
What are we working on?
We've completely rebuilt how data gets into Geckoboard from third-party APIs, thanks to a query planner that's written entirely in Go. Our query planner takes in the metrics that a customer would like to track, and produces a plan for how to fetch and transform those metrics from a third-party JSON API such as Zendesk, Intercom, Google Analytics, etc.
Weâre now working on extending this platform and building various microservices for tracking our customers' rate limits and scheduling metric refreshes in the most efficient way possible. Weâre also creating a caching engine that ensures we don't waste precious API calls on data that we know hasn't changed since last time.
The team are also in the middle of splitting up our existing REST APIs into gRPC microservices with segregated data stores. Which is a huge opportunity for us to rethink some of the fundamental assumptions about Geckoboard's data model and how we can re-architect our systems for greater reliability and to enable us to ship with more confidence.
We donât expect youâll have worked on all of these kinds of projects before, but if they take your fancy and youâre excited about working on distributed systems and database technologies at scale, weâd love to hear from you.
As one of our Backend Go Developers:
Youâll be writing in Golang on a day-to-day basis.
You will help architect, design, and build Geckoboardâs data pipeline.
Youâll maintain and optimise our existing infrastructure and services.
You will get involved in the prioritising and evaluation of our work.
Youâll pair with team members and get involved in code reviews.
Joining us in our London office, youâll be working alongside a growing team of empowered engineers, with a focus on building a high quality product our customers love, work life balance and personal development.
Thousands of businesses use Geckoboard to build live TV Dashboards that focus teams on what matters. We take the complexity out of connecting data and make it simple for anyone to understand key metrics at a glance. We have pre-built integrations with 60+ tools including Google Analytics, Salesforce, Zendesk, Intercom and Google Sheets and our customers include Marketo, Slack, and Skyscanner.
In our mission to make data useful, our growing team of 40+ is headquartered in London and span across eight time zones - from Mumbai to London, San Francisco to Hawaii and more. We're always looking for people with diverse backgrounds who bring unique perspectives and skills to join our team and in return we constantly strive to ensure that we offer the most encouraging, inclusive, and efficient environment possible.
We don't just pay lip service to work-life balance, we actively and strongly encourage it. Flexible working hours and the ability to regularly work from home lets you work in a way that fits you and your family. We see our contractual obligation to offer 25 days of paid holiday as a minimum for everyone in the organisation, not a limit.
We actively contribute to professional development, courses, conferences, and books. Our Engineering & Product team also run fortnightly "Innovation Wednesdays", where everyone has complete freedom to work on anything that interests them, from contributing to open source, to learning a new skill, or improving our internal tools and processes.
