By joining Form3 you’ll get the opportunity to be part of our rapidly scaling business, with some of the brightest talents in tech and payments, working in one of the highest growth sectors for payment FinTech in the world.

We don’t mind whereabouts you are based as we offer the opportunity for our tech team to work remotely. Most of our tech team work this way in fact, by using screen sharing technology to do pair programming. We have found that our team are much more productive that way. 


We are looking for Senior Software Developers who want to be part of building a next generation payment API in the cloud. Our API is built on AWS where all of the infrastructure is defined in code using Terraform. All of the microservices that make up the API are built using Docker containers and deployed automatically using our Travis CI/CD pipeline. The microservices discover each other using Consul and talk to each other through linkerd (service mesh).

We are looking for enthusiastic developers who want to learn cutting edge new tech, 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. 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 greenfield 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 we are mostly based around London, we are operating as a remote team, and typically working from home and pair programming.

We try to pick the right tool for the job, and these regularly change. To give you a flavour though, some of the languages we currently use are: Golang, Java, Python and Ruby.

Some of the tools we use: Terraform, Docker, Vault, Consul, Linkerd Our platform runs in AWS where we use: SQS, SNS, EC2, ECS, RDS and others.


Polyglot: Choosing the right tool to solve the problem is critical, and we expect you to have professional experience with at least 2 different programming languages and multiple platforms and tools.

Distributed architecture: We expect you to have previous experience engineering complex distributed systems, and a view on topics such as service discovery, integration testing, inter-process communication, the best way to define your services and APIs, as well as experience with distributed data stores.

Public cloud: You have worked with public cloud services (AWS, Google Cloud etc.)
TDD/BDD: Code quality is key, and we expect you to have worked with Test-driven development (TDD) and Behaviour-driven design (BDD) and be familiar with the use of tools such as Cucumber.

  • Most of our code is written in Java and Go, so experience with either would be helpful
  • All our services are built and managed as docker containers, so Kubernetes, and general docker experience is preferred. 
  • We like clean code, so experience with Event Sourcing/CQRS will be useful. 
  • We do contract-based testing, using tools such as Pact 
  • We work as a devops team, so experience in automating operations (such as infrastructure as code, automated monitoring and alerting, build pipelines etc) would also be useful. 


      You’ll get the opportunity to be part of a rapidly scaling FinTech company, working alongside some of the brightest talents in tech and payments
      Competitive Salary
      30 days holiday (plus Bank Holidays)
