Software Development Engineer in Test | Luma

At Dotmatics, a Siemens company, we believe science, data, and decision-making must be deeply intertwined for innovation to thrive. Our portfolio includes Luma, LumaLab Connect, ELN Platform, Graphpad Prism, Geneious, SnapGene, Protein Metrics, OMIQ, FCS Express, LabArchives, NQuery, EasyPanel, SoftGenetics and Virscidian. We have a vision for a new Lab of the Future that will change the future of scientific research.

We have created the world’s most comprehensive digital science platform – best-of-breed software applications already used by more than 2 million scientists, together in a single ecosystem united by a powerful, flexible enterprise data platform. This is dynamic, multi-dimensional decision-making. Scientific enterprises need a new level of effectiveness to achieve tomorrow’s breakthroughs.

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 ensure reliability.

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.

In this role you will get to:

• 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.

Who we're looking for:

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.

The Key Skills we are looking for:

• Practical experience with Cypress — writing tests, using selectors and custom commands, debugging failures, and working within an existing Page Object Model.
• Experience testing React applications is a plus.
• Working knowledge of TypeScript or JavaScript, including asynchronous code (promises, async/await).
• Experience with BDD / Cucumber, or a willingness to pick it up quickly — we write most of our specs in Gherkin.
• Test case design and documentation — the ability to break a feature down into clear, repeatable scenarios and write them up so others can follow them.
• Comfort with Git and GitHub, including branching, pull requests and code review, plus experience working in JIRA or a similar tracking system.

You may also have:

• 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).
• 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.

Dotmatics is an equal opportunity employer. We are a welcoming place for everyone, and we do our best to make sure all people feel supported and connected at work.
