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)
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) 🎤

WHO WE ARE
After the 2008 financial crash, the international financial and business environment is more regulated than ever. The amount of required paperwork has increased exponentially. The deals are being blocked, the accounts are being frozen, the business is often getting paralyzed.
Project Plato was born in 2015 as an autonomous R&D unit working for Dolfin, an established British investment company, with the aim of automating sensitive business operations. We are a young and ambitious team frustrated by inefficiency of existing solutions.
5 years later, with the help of our software solutions, Dolfin was able to have
But this is only the beginning. Our mission is to help companies and business professionals around the world communicate with each other and do business with trust and simplified paperwork.
OUR TECH STACK
As a serious, business-oriented company, we develop our solutions exclusively in COBOL.
Just kidding! We use modern and diverse IT infrastructure. Our solutions are web-based, with backends in Golang andPython and frontends in Typescript and React. Data storages include PostgreSQL, DynamoDB and Amazon S3. The infrastructure consists of multiple backend services managed via Kubernetes/Helm, integrated with various AWS and third-party services. We also use Google Bazel, a secure and robust build system.
We strive to make our development process predictable, change-proof and well-organized to achieve the fastest possible product delivery pace without compromising reliability.
OUR TEAM
We are still small: Project Plato is less than 15 people in total but we are planning to grow to 20 soon. As part of the Project Plato back-end team, you will be working closely with Oleg and another 3 senior engineers. Oleg is our lead backend engineer who has been part of the team since 2015 when we established our office in Amsterdam. We are a group that values trust, growth, agility, mutual respect, taking ownership, and learning from each other through a culture of open feedback.

Please note: this position is full time and in Berlin (you need to already be in Berlin too). We don't use agencies.
Most messaging networks are created to serve their creators. Email is designed to serve humankind. For over 50 years inspired technicians have architected email to provide the greatest good to the greatest number. Their openness and design principles made email the world's #1 communication channel and identity provider with 4.2 billion users (2x Facebook). Email is a critical foundation stone of the Web.
Lightmeter is reinventing email infrastructure to overcome threats from centralised tech oligharchs like Microsoft and Google. An epic platform war is behind fought behind the scenes to wrestle control over digital comms and incorporate it into closed service platforms, where the customer is a product to be sold to the highest bidder.
We are 3 years of research and 1 year of development in to building Lightmeter Control Center - the all-in-one mailops management system repeatedly featured in Heise and ZDnet. It's fully Open Source (on GitLab) -- feel free to check the unit and user acceptance test code coverage : ) . Our engineering team has a background in embedded and fintech, with a focus on performance and feedback.
A mix of public and private funding fuels our work, and we've been recognised by the European Commission as part of 'Next Generation Internet'. We have hundreds of active users, a few of whom we interview each week, including banks, public universities, Internet Service Providers, and marketing agencies.
Our mission is to strengthen the foundations of digital society by making mailtech easy and convenient.
That’s a brief intro to what you’ll be working on. But first, you need to know if you’ll even like working with us. Let’s talk about life at Lightmeter and then we’ll go into detail about what we’re looking for.
Who you’ll be working with
One luxuary of being an early-stage team is that you get to work directly with everyone. That said, you'll be reporting to Sam, our CEO. He gets easily excited about engineering patterns and workflows, and likes bright colours and house music with vocals.
You'd work along-side Lead Developer Leandro, who calls himself a Software Craftsman, and who others call a philosopher. Leandro has deeply held unfashionable beliefs like "all code should be fast and light", and cares more about design patterns than what language he's coding in. He love the outdoors and pines for the mountains.
Suela is our Product Manager and x-ray seer of quality and value. She has a nack of turning our telescopes around, pointing out better perspectives, opportunities, and efficiencies. She's an Open Source fangirl, community organiser of the OpenLabs Hackerspace, and secretly learning Python so she can make bots to replace herself. Just kidding!
How You’ll Work at Lightmeter
We work hard to make working here a great experience, and have a team of truly exceptional people — the kind you’ll be excited to work with. You'll get to design and create new components and services, working on features like those on our roadmap (https://lightmeter.io/roadmap).
Here’s how we operate
No Crazy Hours
You'll very rarely work more than 40 hours per week, unless you really want to. Ocassionally things can heat up, but noones going to force you to work more than is comfortable. When you do work overtime you balance it out with time off afterwards. We work hard and smart, planning carefully, but we’re in this for the long haul: sustainability trumps anything short term.
Face time and alone time
Most of us have worked fully remote before and miss the benefits of face time, so we like to work together a lot of the time. However focused time alone, in cafes or home-office is nice too, so we aim for a good mix. So long as you can reach the people you need, when you need them, and vice versa, your preferences for office vs remote work shouldn't be an issue.
Take Vacation
A small team means it's easy to coordinate time off to relax and recharge. Notice you'll be away a week in advance is usually enough.
Up Your Game
We’re serious about helping you improve your craft. Everyone wins when you get better and your job, and enjoy the process. Think conferences, online courses and subscriptions, dedicated time away from work to learn something new.
Compensation and Legal
We can't currently offer you a salary to compete with Amazon or Microsoft. What we can offer you is the same salary that we are paying ourselves: €50,000 / year.
We’re an early-stage startup, funded, pre-revenue, and growing. We are owned and managed by our Founders. Making sustainable, profitable products with a committment to openness is hard; we're demonstrating how it's done. If you care deeply about digital freedom, empowerment, and collaboration, you'll probably fit right in!
What we're looking for
Lightmeter has ambitious goals and our team is growing to meet them. You're the Software Engineer we're looking for if you're collaborative, mission-motivated, creative, disciplined, and productive. (So far, so good?)
You love solving complex problems — both internally and for your users — and know what it means to build a mature, evolving product. You are more focused on the outcome than on the output of your work, and prefer to deliver something useful sooner, rather than something perfect later. You welcome feedback, and are curious about users' challenges and how to address them. You demand a lot from your colleagues and expect the same in return, taking personal pride in collective achievement.
