You will work within a small team where you will pair-program to:

  • Build resilient and adaptable fintech platforms and components in Java
  • Refactor to improve code design
  • Write lots of tests (every one of our commits is continuously and rapidly verified by thousands of tests)
  • Automate the boring bits

Features of the way we work:

  • We avoid silos by regularly rotating between teams to work on the whole system with an Our Code not My Code mindset and approach
  • We practice trunk-based development and continuous integration: we treat every commit as releasable
  • We treat broken tests as failures and revert where possible
  • We practice TDD, BDD and DDD
  • We automate as much as possible
  • We pair program to ensure that everyone understands the context of what they are working on. We also believe that pairing drives quality, learning, cross-skilling, and builds empathy with other developers
  • Sometimes we have to care about throughput and latency and so take this into account when writing code
