Software Development Engineer in Test

We are seeking an SDET to join one of our agile engineering teams and help us build quality into LUMA, our scientific software platform. You'll take ownership of testing for a specific module of the application — writing and maintaining automated tests, exploring new features, and working alongside developers, application scientists and DevOps engineers to make sure what we ship is reliable.

This is a hands-on automation role with room to grow. You'll be contributing to established test frameworks rather than building them from scratch, with support from senior SDETs who will help you develop your technical depth and your understanding of the science behind the product.

While the primary focus is automation, the role also involves manual exploratory testing.

Write, maintain and extend automated test suites for your module using Cucumber, TypeScript and Cypress (and Playwright where we use it).

Own day-to-day quality for your area: contributing test scenarios during planning, testing stories as they're built, and giving the team a clear picture of release readiness.

Design and document test cases that cover functional, regression and integration scenarios, and keep them useful as the product evolves.

Investigate and reproduce defects, raise well-evidenced bug reports in JIRA, and verify fixes with developers and scientists.

Keep your tests green and trustworthy in our CI pipelines, and help improve how tests run and report.

Learn to read and interpret API documentation and turn it into meaningful automated coverage.

Work with leading experts in software development, scientific product management and test automation — and be mentored by them.

You'll have 2–5 years' experience in QA/testing, including at least a year of hands-on test automation . You're comfortable working in a code-first way, you enjoy digging into how things work, and you're happy asking questions when a domain is unfamiliar. You work carefully and pay attention to detail, and you can take a story or module, understand it and devise a concrete approach to testing going above and beyond the standard acceptance criteria.

Just as importantly, you want to get better. We're looking for someone who takes feedback well, is curious about the scientific problems our users are solving and wants to grow into a senior automation engineer over time.

Experience with Playwright, or interest in learning it — we use it for a subset of our tests.

Exposure to API testing tools (Postman, REST clients) or writing API-level automated tests.

Any experience with performance or load testing (K6 or similar).

Familiarity with validating data integrity across release upgrades, migrations or schema changes.

A background or interest in science, engineering or research software.

Research shows us the confidence gap and imposter syndrome can get in the way of meeting outstanding candidates, so please don’t hesitate to apply — we’d love to hear from you.
