🗨️ About the Team

• The candidate will work as part of the Product Management team and support the wider AI Platform and AI Research departments.
• The Product Management team is the main support team for AI Platform, handling project management, product management, QA, and design.

• The AI Platform department provides several key tools for AI researchers and medical professionals within Lunit to help accomplish our mission of conquering cancer. The department primarily focuses on radiological and pathological image annotation, data cataloguing and management, and data pipelining and automations systems to help internal customer departments move fast to deliver value.
• Our team is an international team of enthusiastic researchers/engineers with a diverse set of interests and a strong will to exchange knowledge and collaborate on interesting projects.

🗨️ About the Position

• The role has four key responsibilities:
• Ensuring that our requirements aren’t missing any major gaps (requirements defects)
• Ensuring that our designs properly fulfill requirements (design defects)
• Ensuring that our software accurately reflects those requirements and designs and is of generally high quality (software defects)
• Ensuring releases are well-documented, well-communicated, and that go/no-go are managed well (releases)
• AI Platform’s software engineers currently produce automated testing, but a great Quality Assurance Engineer thinks differently. We expect our QA Engineers to come up with test cases that software engineers have trouble even imagining. The QA way of thinking is its most valuable asset. The ideal QA engineer not only captures major edge cases and tests them but also automates these tests to bring ever increasing efficiency to testing.
• As the AI Platform department is a back-office department: that is, our customers are other employees of the company. Our timelines are mostly under our control. Unlike other industries like the game industry, crunch time and overwork are very, very rare; however, the testing cycle is ongoing. This means your days will be busy, and you generally won’t need to work late.
• Additionally, Release Management will be a core responsibility. It is a nascent practice within the department, but the ideal candidate will maintain customers' trust in the release process and ensure all necessary artifacts are in place for historical tracking and audit compliance.
