Job Description

About Cuvva

Cuvva is making car insurance radically better.

We’re creating truly flexible products that meet people’s 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 we’ve sold over 3 million policies and supported over 450,000 customers. We’re a world-class team of over 100 people, passionate about solving our customers’ problems. Join us.

Why work for Cuvva?

We don’t 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 business–including our CEO & Founder Freddy–is 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! Here’s a blog post on our ‘Cops Club’.

We’ve 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 we’re comfortable giving and receiving honest feedback, and trying new ways of doing things.

We’re 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 don’t love insurance, trust us, you’ll love what we’re building.

About the role

You’ll work in one of our cross-functional product squads, helping the team achieve their goals - whether that’s 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 don’t just write code or implement against a spec. You’ll 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 don’t 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 we’re 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 “legacy” 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 “Showing off our K-sortable IDs” our blog

“How we analyse and test new pricing models” our blog

“How we test and roll out new product features” 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

• We don’t 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

• Know your way around the major AWS services (or similar cloud services), and have an enthusiasm for cloud services in general

• Be comfortable working with containers (e.g. Docker, K8S, ECR, container based CI platforms)


Perks & Benefits

Benefits

As well as a competitive salary (£75-90k, dependent on experience) and equity based remuneration, benefits of working at Cuvva include:

• Brand new MacBook 💻

• 33 days holiday (inc public holidays🌞)

• 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 🧠

• 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 🚲

• Season ticket loans 🚂

• A volunteer day

• Office library full of great books 📚

• Great coffee machine in the office ☕️

• Fully stocked beer and soft drink fridge (we do team drinks every Thursday)

• Monthly team outings or remote events (so far we’ve done things like karaoke, go-karting, bowling and comedy nights) 🎤

Numus Logo
Senior Go Backend Architect & DeveloperSponsored
Numus
Remote / Zug, Switzerland
$70,000 to $130,000 a year
June 2021
5 Applicants This Week

Job Description

Make a difference in an innovative team and build a world class big data research platform.

Numus is a global group of quantitative, engineering, and blockchain experts. We are contributing to shape the future of applied decentralized finance. We are a native global and decentralized team with an office presence in Zug, Switzerland. We combine extensive and diverse experience from the Crypto, Quant, Tech and Finance worlds but are bound by a shared passion for sharing ideas, learning from each other and solving new problems together.

Are you keen to work in a startup where your ideas, experience and willingness to find creative solutions – and not your title – makes a difference?

You will help design, create and improve our central automated trading platform, written mostly in Go. You will help to make our architecture even more secure, resilient and fault-tolerant while maintaining a modular, well-tested architecture with simple and elegant code, focussed on speed and latency. A good line of code for you is the one which wasn’t written. You see infrastructure as code and see the deployment and monitoring as an integral part of your work, DevOps-style. You rather try to use a AWS cloud service instead of running your own piece of infrastructure or code. Security is always on your mind, and you’re maybe always a little bit too paranoid. You will also help research developers to port their Code to Golang and maintain code quality. You love to explore new state-of-the-art tools and discuss them with your team. Contributing to Open Source projects (e.g. modules to connect to exchanges) is an important part of your work as well. You’re super detail and quality oriented and love to work in a team where most problems haven’t been solved so far – so we highly value creativity to find solutions.

Requirements

  • Deep understanding of modern cloud-based backend architectures and technologies
  • Golang coding experience
  • Database technologies, especially latency-focussed NoSQL (AWS DynamoDB, Redis, ElasticSearch, AWS S3)
  • Distributed Systems (gRPC, Redis)
  • DevOps deployment on AWS (Docker containers, AWS CloudFormation/CDK, AWS Opsworks, AWS ECS/Fargate)
  • Maintaining a CD/CI Pipeline (AWS CodePipeline/Build/Deploy, Github Actions, TravisCI)
  • Monitoring tools (AWS X-Ray, AWS CloudWatch, Datadog, Honeybadger, New Relic)
  • Security Tools and Concepts (especially on AWS: VPC, IAM Roles, Security Groups)
  • Excellent problem-solving skills and high attention to details
  • Highly self-organized, self-learner, strongly quality oriented
  • Fluent English speaker

Beneficial Requirements

  • Analysis and math skills
  • Experience with Python, JavaScript/TypeScript (AWS Lambda) and Ruby (on Rails)
  • Experience with Serverless technologies (AWS Lambda)
  • Experience with big data management and analysis toolchains like Databricks, Apache Spark, Kinesis
  • Extended know-how about security, hardening and attack vectors
  • Interest in crypto and/or financial markets How to apply

What we offer

If you are eager to join a knowledge driven group of brilliant minds that value results above anything and do not engage in any political internal discussions, then you should join Numus.

As everyone of us is constantly learning and we are far from definitive answers yet, we embrace a global, diverse and collaboration-oriented team culture. We value open, smart and sharp minds, no matter their background. They are our greatest asset.

If you are curious, scientifically minded, entrepreneurial, passionate, a little bit quirky and fun: we would like to get to know you and become a part of our journey. Develop your skills together with us in a humble, remote, lean and agile environment.

We operate in a non-hierarchical structure on a self-management basis where skill counts instead of titles. Take initiative, initiate change and take responsible action. You also know when to ask for help.

You’ll be working with the latest cutting edge technology to solve real world problems. Creativity is a must in our company. We’re organized as a full remote-first company, so Everybody can choose freely to work remotely or from our offices or a mix of both, we will be able to adjust to your work-life balance.

July 2019
2 Applicants This Week

Job Description

About Herdius:

Herdius is a Berlin based Blockchain Company. We are working on building homomorphic distributed private key generation which then is turned into value bearing products in different sectors. Currently we are very close to open beta-testing for the Herdius-Crypto-Wallet.
What we focus on on the blockchain field specifically is interoperability and trading. When connecting different chains on the key level, users can eliminate communication channels, bridges and complex systems. In other words, users can do cross-exchange and chain token swaps very conveniently and profitably for the user due to the cross-exchange arbitrage opportunities. The broader vision is one day to replace API auth keys with public-private key cryptography in order to provide layered access to user data.

All this makes for a crypto eco system and hedge fund that pays interest on all cryptocurrencies (that right now are unfortunately somewhat unusable and just laying around on wallets).

About the role:


Herdius is seeking for a Gopher Guru - an experienced Senior Golang Backend-Developer - to join our team of smart and visionary individuals. Experience in Blockchain is not necessary but a big plus.

We do not look at this role as another standard job but rather as great opportunity to build something really meaningful und amazing. Become a member of our great collective of top nodge engineers and people - altogether working to create cutting edge tech for the masses.

Besides the Herdius HQ in Berlin our Dev-Team is working mostly remote on different time-zones - so this vacancy surely also is location agnostic.

We would expect you to contribute at least 20hrs per week for part-time but joining full time is possible, too.



Cool things you will work on:

  • Implementation and design of Herdius’ consensus algorithm and p2p order routing protocol.
  • Lots of work around trading and high volume data handling and transfer.
  • Design and implementation of a low-latency, high-availability, and performant algorithmic hedge fund and exchange order book.
  • Integration of the Herdius distributed private key generation protocol.
  • Constant performance testing and improvement of our architecture.
  • Working on new financial products that have not been seen in the crypto world, setting up the base-layer infrastructure of a trading system and hedge fund

Skills & requirements

  • Strong proficiency & experience working with Golang
  • 3+ years of experience as a backend engineer, language agnostic but Go, React, NodeJS, Vue.JS, Scala, Angular, Rust preferred
  • Experience and passion working with distributed systems and networking
  • Strong interest in blockchains and related technologies
  • Passion for delivering quality, secure code with loads of testing
  • User authentication and authorization between multiple systems, servers, and environments
  • Interest in privacy and cryptography, trading and financial service
  • Understanding fundamental design principles behind various consensus algorithms
  • Understanding differences between dPOS, DAGs, Plasma, BFT, aBFT, etc.
  • Implementing automated testing platforms and unit tests
  • Proficient understanding of code versioning tools, such as Git

Interview Process

Your education or professional experience at the end of the day does not matter to us. It all comes down to us being convinced by your skills and drive! 
We mainly look for people who are passionate about projects they work on and have the drive to see a project through. Our code is mostly done in Golang with some Solidity for connectivity with Ethereum.

How to apply:

Send anything that reflects on your knowledge and experience in the field. Besides a CV/LinkedIn-profile you can send links of your GitHub/Stack Overflow/Portfolio/ or something awesome you’ve built that you’re simply proud of.

Job Description

Job Description

Luxor specializes in the physical delivery of hashrate (compute power). Over the past three years we have been acting as a buyer of hashrate, purchasing, and mining over $45mm worth. We currently have 35,000 machines that sell us their hashrate daily.

Company Background

We fundamentally believe that compute power itself is a commodity and we want to build out traditional marketplaces and derivates for it.

We are building a spot-market for hashrate, not dissimilar to a compute-power version of Henry Hub. After this is completed we will begin building incredibly powerful and interesting derivative products on the value of hashrate.

You will develop the technical design for either cloud or on-premises solutions. Also, influence designs across R&D using original research and advanced analysis. You’ll design solutions for business-critical and highly complex engineering projects by applying extensive domain expertise in performance testing. You’ll provide oversight of code and design reviews, and ensure features are delivered to meet business and quality requirements.

Our teams own mission-critical aspects of a rapidly growing, globally distributed platform (eg: Hashrate Marketplace and 15 unique mining pools), in the cloud, and, as such, you will have an incredible amount of impact on the current state and future direction of our product, with visibility throughout the organization and a significant opportunity to take ownership.

This role will report directly to the CTO.

This is a remote role but you need to be based between UTC-8 and UTC-3 timezones.

Option to be paid in Bitcoin. Equity package.
