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.

About you:
You understand how computers work and what role an operating system plays. You know why the Linux kernel is written in C and not any other language. You have a favorite file system, you know what a syscall is and you are comfortable exploring /proc and /sys. You like using Go every day, are not afraid of Makefiles and you enjoy when thousands of servers bend to your will.
You should also be comfortable joining an early stage company with a dynamic future. We offer a great salary, but expect you to value the equity as well. In return we will be very transparent with you about the company finances and outlook. You are joining a founding team and we want you to enjoy the ride.

We are also dedicated to our friends, families, and hobbies outside of work. Our past experiences building companies taught us about the importance of life and work balance. It matters even more when you are building a lasting company, like Gravitational.
