Software Developer in Test (C# or TypeScript)
London | Hybrid 3 days per week | £65,000 to £75,000 base plus discretionary bonus
Ncounter is partnered with a high-performing technology team who are looking for an SDET to help deliver complex, user-facing products. This is a role for someone who thinks like a developer but specialises in quality, working side by side with engineers to ship reliable, well-tested features at pace. Personality is just as important as technical expertise; they want someone collaborative and personable who will strengthen the team culture.
You’ll be joining the Web Engineering group, which works across React and C#, and the role sits within a developer-in-test model that blends QAs and developers. The team is made up of juniors through to a team lead, with a strong culture of collaboration, reviews and shared learning. Hybrid working is three days per week in a new central London office.
Key Responsibilities
* Design, extend and maintain modern automation frameworks
* Develop reliable UI and integration tests with Playwright or Selenium
* Collaborate with engineers to improve testability and overall code quality
* Contribute to CI/CD pipeline improvements
* Support delivery of key projects across the web portfolio
Must-have Skills
* Strong coding skills in C# or TypeScript
* Experience with at least one framework: Playwright or Selenium
* Ability to read and work with full-stack code (React / C#)
* Understanding of automation within a developer-in-test environment
* Clear, collaborative communication style
Nice to have
* Knowledge of DevOps practices and CI/CD pipelines
* Broader test automation experience across multiple tools
* Exposure to cloud environments
The interview process is structured and efficient: an initial 30-minute call with engineers, a focused take-home task in C# or TypeScript, then an onsite session with senior engineers and stakeholders.
If you are motivated by building frameworks, improving automation reliability, and embedding quality at the heart of engineering, we’d like to hear from you. Please send your CV to Ncounter with a short note on your recent automation work and the impact it delivered.
We are an equal opportunities employer and welcome applications from all qualified candidates.
