Salary
: £70,000 - £80,000

OnSite
: 3 days per week on-site (Putney)

I'm looking for a SDET to join a client of mine based in Putney, they build SaaS products in the TechforGood space.

Really important pointer:
The SDET will be a technical partner, writing code and collaborating with developers to ensure features are built with quality baked in. They should be positioned as a senior engineer with a specialisation in test automation and quality engineering, rather than someone who only executes test cases.

We're looking for a Senior Software Development Engineer in Test (SDET) who will act as a development partner rather than a traditional QA resource. This role is highly collaborative and embedded within our feature development process. This person will work closely with developers to ensure that automated tests align with business requirements and provide meaningful coverage without wasting effort on unnecessary edge cases.

Key Responsibilities

-Collaborate with developers during feature development to design and implement automated tests that validate core business functionality.

-Own and enhance unit and integration testing across our services and platforms.

-Write and maintain automated test suites that are robust, scalable, and integrated into CI/CD pipelines.

-Advise on testability and quality during code reviews and architecture discussions.

-
Ensure that tests are business-driven, focusing on real-world scenarios rather than exhaustive edge cases.

-Partner with teams across Ruby backend services and iOS/Android workstreams to ensure consistent quality standards.

Technical Environment

Primary backend: Ruby / RSpec

Working with iOS / Android developers is likely

Testing focus: Automated testing (not manual QA)

Likely Ideal Candidate
:

  • Good experience in test automation frameworks and tools (preferably in Ruby and mobile ecosystems).
  • Strong understanding of the SDLC-—this is a coding-heavy role, not manual testing.
  • Ability to think like a developer and contribute to code quality, not just test coverage.
  • Comfortable working in cross-functional teams, influencing developers and product managers on quality strategies.
  • Experience with CI/CD pipelines and integrating automated tests into deployment workflows.
