About the project

We are looking for a hands-on AI QA Lead to join our client’s B2B SaaS product with AI-powered functionality. The development team actively works with AI agents, and we need a strong QA specialist who can own product quality, build a QA process that fits this way of working, and catch issues before they reach production.

The engagement starts with a 4-week pilot. A successful pilot can lead to long-term cooperation and growth of the QA team.

This is not a purely managerial role. We need someone who tests, analyzes changes and finds problems themselves.

What you will do

• Build and implement the product testing strategy
• Define and introduce QA Gates for development and QA - clear quality criteria that changes must meet before merge and release
• Shape test strategy independently based on user goals, tickets, previews and product context
• Analyze requirements, spot gaps and ask the right clarifying questions
• Identify risks and check related functionality that may be affected by changes
• Perform functional, integration, regression and exploratory testing
• Test AI features: evaluate system behavior, response quality and edge cases
• Review pull requests and code changes from a QA risk perspective
• Track issues through to fix, run retests and assess release readiness
• Write clear, prioritized bug reports with steps to reproduce, expected and actual results
• Give release recommendations, flag critical risks and clearly state what remains untested
• Coordinate QA work and keep testing transparent for the team

Requirements

• 5+ years of commercial experience in Software QA
• Experience as QA Lead or Senior QA Engineer
• Hands-on experience testing AI/LLM-powered features in real SaaS products
• Experience working in AI-driven teams (development with AI agents) and building testing processes for them
• Strong background in B2B SaaS testing
• Excellent exploratory and risk-based testing skills
• Ability to understand complex products independently and decide on testing depth and priorities
• Experience in API and integration testing
• Understanding of code review from a QA perspective
• Experience working directly with developers and Product Owners
• Fluent English and strong communication skills

Nice to have

• Experience evaluating LLM output quality: consistency, hallucinations, unexpected model behavior
• Test automation experience and a clear view of what is worth automating
• German at a working level
• Experience with European B2B SaaS teams

What matters most

The key criterion is independent product judgment. We are looking for someone who doesn’t wait for a ready test plan, but:

• understands the user goal and decides how to verify it
• sees problems beyond the written acceptance criteria
• asks the right questions and finds missing information
• finds risks in related scenarios and functionality
• makes a well-argued release recommendation

Hiring process

Candidates who pass the initial screening will be offered a short paid practical assignment (about half a day). It helps us understand your real approach to testing, your independence and the quality of issues you find.

Format: contract, starting with a 4-week paid pilot
Workload: full-time during the pilot
Location: Europe, remote
Working hours: overlap with CET (approx. 10:00-17:00 Berlin time)
Languages:  English - Upper-Intermediate ; German is a plus
