This is a 100% remote role. UK/EU based only.
We are looking for Senior Software Developers who want to help build the next generation payment API in the cloud.
We’d like to hear from enthusiastic polyglot developers who want to work with the latest technologies, solve interesting problems and be part of a really great team. There are a wide range of problems to tackle, from configuring nginx proxies to writing custom payment routing and handling logic, and we contribute open source back to the community. We believe that the language you write the code in is just how you convey your solution to the computer and the real value is being able to think through a problem.
You will be working on new development projects, focused on best practice across the board, including automation of absolutely everything (Terraform for infrastructure deployments to AWS, CI/CD with contract-based testing and auto-deployment of services within Docker containers, etc.), pair programming and TDD/BDD. Although many of us live around London, we are operating as a remote team, and typically working from home and pair programming.
It’s very much a “best tool for the job” mentality at Form3 and our tech-stack is always evolving but to give you a flavour of what we’re currently working with here are some of the tools we use;
We don’t mind whereabouts you are based as we offer the opportunity for our team to work remotely from anywhere in the UK or EU. In fact, most of our Developers work, utilising screen-share technology and pair-programming to share knowledge across the team. That being said, we also have London and Amsterdam offices, so should you occasionally wish to work from these, you’d be most welcome.
Whilst experience of the above technologies would be nice, it is by no means essential. We are looking to speak with well-rounded software professionals who have a breadth of experience across a variety of programming languages, are passionate about tech and enjoy working collaboratively within a team.

At Geckoboard we help businesses use their data to align their teams on the metrics that matter most to them. We’ve 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, we’re 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.
We’re 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. We’re 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 don’t expect you’ll have worked on all of these kinds of projects before, but if they take your fancy and you’re excited about working on distributed systems and database technologies at scale, we’d love to hear from you.
Joining us in our London office, you’ll 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.
Keen to hear a bit more? Carlos, one of our Backend Go Developers has shared a little about what it’s like working with the team, what an average day looks like and more in an interview on our Blog: https://medium.com/geckoboard-under-the-hood/working-at-geckoboard-as-a-go-developer-e73855bd0dd8
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.
And, don’t take our word for it, see what the team say about the projects they work on: https://medium.com/geckoboard-under-the-hood and their experience of working with us on Glassdoor: https://www.glassdoor.co.uk/Reviews/Geckoboard-Reviews-E878996.htm.

You should thrive in a constantly changing environment and enjoy learning new things at a fast pace.
Our team takes pride in owning our work truly end-to-end. We’re looking for people who can plan, experiment, build, test, deploy, measure and iterate before calling it done. As a small team, we try and build on the shoulders of giants, which means that you’ll often find us working with the latest and greatest technologies.
If you don’t feel like you fit all of these areas, don’t worry. We are dedicated to the development of our team. Whether you’re a computer science graduate, an artist or a bricklayer, as long as you’re also a programmer, we’d love to hear from you.
Please note that the package for this role will include equity.

When we refer to the “core platform”, we mean the services which underpin the processes of all insurance activities on our system.
For example, we expect one of these to be the “policy service”, which might be responsible for ensuring compliant issuance of policies, coordinating mid-term adjustments, preventing overlapping policies (double insurance), etc.
Other services could include user authentication, risk & pricing calculation, handling the process of modifying user data in-line with any mid-term adjustment requirements.
All services we consider to be part of the core platform will have strict requirements around stability, data integrity and transactional safety. All functionality must fail safely and explicitly, for example using 2-phase commit processes or other similar techniques. This will also require a reasonable level of testing to validate this safety.
The perfect addition to our team will have:
We are a small team so it is important that the successful candidate is not only technically highly competent, but also a great cultural fit!
As well as a competitive salary (£60-75k, dependent on experience) and equity based remuneration, benefits of working at Cuvva include working in our new offices in Shoreditch and of course significant savings on your car insurance.🔗 Link
