What do we need We are seeking a Senior SDET to join our team and contribute to the development of cutting‑edge scientific software products, including LUMA. In this role, you will play a critical part in driving quality across the engineering lifecycle through a combination of strategic test planning, robust automation, and close collaboration with cross‑functional teams. As a Senior SDET, you will take ownership of designing and evolving test frameworks, expanding automation coverage, and continuously improving quality engineering practices. You’ll work closely with developers, application scientists, and DevOps engineers to proactively identify risks, validate complex functionality, and ensure the delivery of reliable, high‑quality software. While the primary focus of this role is automation, it may also involve aspects of manual exploratory testing, particularly in early‑stage features or areas with high scientific complexity. In this role you will get to

Lead the design, development, and maintenance of scalable automation test suites for web‑based scientific applications. Define and execute comprehensive test strategies and plans that ensure high test coverage across functional, regression, integration, and system levels. Collaborate with product teams to identify test scenarios, reproduce complex defects, and validate bug fixes in coordination with developers and scientists. Drive quality engineering best practices and contribute to continuous integration and delivery (CI/CD) workflows. Ensure accurate documentation of test results, automation processes, and framework enhancements. Work with leading experts in development, scientific product management and other excellent SDETs. Contribute to the overall test architecture and mentor junior QA and automation engineers as needed.

We are looking for people who have at least 6 years’ experience in QA/Testing, including at least 4 years focused on automation, and who demonstrate the ability to work autonomously, with a methodical, detail‑oriented approach. You should be confident owning complex test initiatives end‑to‑end, driving quality strategy, and delivering reliable automation in fast‑paced, collaborative environments. The Key Skills we are looking for

Expertise in Cypress, including the use of custom commands, advanced debugging, plugin integration, handling Shadow DOM elements, testing React‑based applications, and implementing scalable Page Object Models. Strong command of TypeScript, particularly with features such as interfaces, generics, and asynchronous programming techniques used in building robust, maintainable test code. Proven experience in test case design and documentation, with a focus on creating comprehensive and reusable test scenarios that support long‑term quality goals. Ability to effectively interpret API documentation and translate it into high-quality automated test coverage, while also writing clear, maintainable documentation for test frameworks, tools, and QA processes. Deep understanding of Git, including advanced usage of Git workflows, branch management, and experience collaborating within structured environments using JIRA or similar tracking systems.

You may also have:

Experience building and executing performance tests using tools like K6 or similar load testing frameworks. Familiarity with data integrity validation strategies, particularly in the context of release upgrades, data migrations, or schema changes.
