Software Development Engineer In Test (SDET) ? Would you love to have a job where you:

  • work with the latest cutting edge technology and practices?

  • have a competitive salary, benchmarked against a peer group of the most innovative fintech companies in London?

  • have a flexible workplace that likes to say yes?

  • have 25 days holiday per year + your birthday off!?

  • have tech equipment of your own choice bought for you to work with?

  • have free onsite Nuffield Health Gym and pool?

  • work in a great location next to the Thames?

  • have tons of opportunities for progression and development (including managing your own team in the future)?

Then this is a fantastic opportunity for you in a high profile project working on a new cutting edge consumer FX card product that will be used by over 7000 customers globally developed with an innovative tech stack (PostgreSQL, Express, React, Node.js). We are seeking a passionate and experienced Software Development Engineer In Test (SDET) to join a 50 person technology team in London (there is also a 10 person team up in the north of England) which has a fun, fast-moving, hardworking and exceptionally supportive environment.

You'll have a huge impact on the quality of a £2 billion company's growing suite of products and services.Use your knowledge of testing and testability to influence better software design and promote proper code quality practice, bug prevention strategies, accessibility, privacy, and other advanced quality concepts across our products.


You Will:

  • Improve developer and engineering team’s test coverage, release velocity and production health

  • Work closely with development teams in instrumenting their workflow to build a comprehensive picture of velocity, coverage and quality

  • Develop modern testing frameworks for a microservice architecture

  • Be involved in research and implementation of new testing strategies, such as Component and Contract Testing

  • Act as a consultant to different development teams, show them how to implement new testing strategies

  • Mainly write in TypeScript (most of the Engineering team writes in TypeScript)

  • Use BDD to bridge the communication gap between product, business and engineering

  • Be a para-developer -> help developers ship higher quality products faster


Please apply for this role if you are a Software Development Engineer In Test (SDET) with the following experience:

  • 2+ years of experience as a developer or SDET

  • Strong Testing framework development background

  • Strong debugging and problem solving skills

  • Experience in UI or API automation

  • Proficiency in at least 2 software programming languages

  • Ability to drive for results and independently own testing strategy and delivery

  • You’re constantly curious about new technology and approaches


It would be extra awesome if you have:

  • Experience with infrastructure-as-code delivery pipelines (such as Jenkins-pipeline, AWS Code Build or CircleCI)

  • Experience with React, Node.js or Typescript

  • Experience with developing testing solutions for Mac, Unix or Linux environments.

  • Familiar with SQL

  • Show creativity and initiative to improve product coverage and effectiveness.

  • Excellent leadership, communication, collaboration, reporting and analytical skills
