Thought Machine, one of the UK's leading fintech companies, is undergoing a period of rapid expansion and is looking to hire a number of candidates in the role of Software Engineer in Test.

Our mission is to cure one of the banking industry's primary problems: its reliance on outdated IT infrastructure. Nearly every bank is stuck on a legacy IT platform, which cripples their ability to innovate and give their customers the type of service they deserve.

Our solution to this is Vault: a complete retail banking platform that is capable of being configured easily to suit the needs of any bank. We have built Vault from the ground up as a cloud native, microservice API architecture platform. Thought Machine has a deep culture of engineering excellence, and we believe it is this which delivers a solution compelling enough to engender a seismic shift in the banking industry.

Thought Machine is looking for highly talented individuals to help grow the company and achieve our ambitious goal. We pride ourselves on having an excellent internal culture, where we strive hard to create the best possible working environment; a healthy mix of great technical work, fast pace, supportive atmosphere, and of course our irreverent sense of fun.

Thought Machine hires team members of excellent calibre in every role. While a lot will be asked of you, you will benefit greatly from working in a world class team, with colleagues who excel. Working at Thought Machine is fast paced and team oriented with an emphasis in delivering the highest quality work in every role.

Thought Machine is looking for Software Engineers in Test to augment our world-class engineering team with engineers working specifically on our test infrastructure. Automated testing is a central part of our workflow and as our products grow in capability we are creating this role to specifically support the testing infrastructure that underpins their delivery.

This role focuses on building tools & frameworks for testing and automating every part of our testing that can be automated (and hopefully a few that can’t as well).


  • Designing, implementing and developing frameworks supporting the testing of our products.
  • Driving continuous improvement in testing technologies.
  • Working with engineers to deliver enhancements to our development processes.
  • Leading automation of existing manual processes.
  • Helping ensure that we can continue to deliver software at high velocity



  • Our main programming languages are Python and Go, and ideal candidates will be strong in both. We are happy to look at candidates with experience in other languages like Java or C++, so long as we believe that the candidates can get up to speed with Python or Go quickly.
  • Experience in developing automated tests as an integral part of the development cycle.
  • Experience with testing frameworks & infrastructure (e.g. ginkgo, cucumber, behave, selenium, etc).
  • Familiar with best practices around unit testing & code coverage.


  • Experience with REST APIs and equivalents such as gRPC.
  • Experience with AWS or other cloud providers.
  • Familiar with common CI and analysis tools (e.g. CircleCI, Travis, Coveralls, Codecov, etc).
  • Experience with client/server software architectures & networking, or microservice architectures.
  • Experience with modern hermetic build & test systems (e.g. Please, Bazel, Buck, etc).


  • Competitive salary
  • Pension
  • Healthcare (including dental & optical)
  • Other perks like sports clubs, healthy (and sometimes not so healthy) snacks, tea and coffee
  • A talented & experienced team as your colleagues
  • An environment where you can learn and progress
  • Friday team wrap up with drinks and food

  • Thought Machine are committed to making a measurable positive impact on people's everyday lives. We are an equal opportunity employer and value diversity at our company.
