About kaiko.ai

kaiko.ai is building a next-generation agentic clinical AI assistant that helps clinicians reason across patient data, guidelines, and diagnostics. 

About the role

As we scale our product in a clinical setting, the cost of quality gaps grows, both in engineering velocity and clinician trust.

You’ll step in as our senior hands-on QA engineer, shaping how we test, verify, and release software within the development team. You’ll ensure quality is built into the process, not bolted on: improving test coverage, traceability, and engineering practices around verification.

It’s a high-impact, high-ownership role: you’ll work side-by-side with engineers, influence technical decisions, and help us ship robust, reliable software that supports real-world cancer care, without owning regulatory or project management overhead.

You will be based in The Netherlands or Switzerland, with the expectation of spending at least 50% of your time at the office.

Some areas of responsibility

• Lead the design and execution of test strategies across manual, automated, and regression testing

• Ensure all software changes are verified against requirements, with clear, audit-ready traceability

• Drive improvements in test automation, CI/CD quality gates, and release validation workflows

• Mentor engineers on QA practices and foster a culture of quality ownership across the team

About you

• 5+ years in QA or testing roles, with deep hands-on experience in software development environments

• Proven track record in improving QA processes within engineering (e.g., traceability, test coverage, automation)

• Strong technical skills: experienced with test frameworks, APIs, CI/CD, and tools like Jira, Git, and Confluence

• Proactive and analytical: you spot gaps before they become problems and move fast to fix them

Nice to have:

• Experience in regulated environments (e.g. medical devices, IEC 62304, ISO 13485)

• Hands-on scripting or automation experience (e.g. Python, Cypress, Playwright)

• Familiarity with testing AI/ML-driven applications or clinical software

We are excited to gather a broad range of perspectives in our team, as we believe it will help us build better products to support a broader set of people. If you’re excited about us but don’t fit every single qualification, we still encourage you to apply: we’ve had incredible team members join us who didn’t check every box!
