What we offer

- Access to real production data and immediate user feedback
- Close collaboration with the engineering lead
- Remote-first, data-driven culture
We are developing into one of the leading software-based personnel service providers for skilled workers in Europe. For over 40 years, the Trenkwalder Group has stood for continuous growth, entrepreneurial strength, and reliable partnerships in personnel services. With more than 200 locations in 16 countries, around 16,000 employees, and a turnover of 600 million euros, we are already one of the leading HR service providers in Central and Eastern Europe.
Our focus is on qualified professionals—the backbone of the European economy—and on the consistent integration of modern technologies. Our mission is to fulfill the European promise of free, cross-border work. Our success is based on long-standing customer relationships, trust, and quality, as well as on continuous development through innovative technologies.
Your Tasks
Our platform uses AI for complex tasks: automated matching, profile analysis, anomaly detection. We know the algorithms work — but we want to understand how well, and where they can improve. That's where you come in.
- Analyze the quality of our core AI-powered features: where do the algorithms perform well, and where are there systematic weaknesses?
- Build metrics and dashboards to measure platform quality (conversion, adoption, deviation analysis)
- Evaluate user behavior: how do users interact with AI-generated recommendations?
- Propose data-driven improvements for existing algorithms — evidence-based, not intuition-based
- Build evaluation frameworks for AI outputs (structured scoring, comparison runs)
- Work closely with the engineering team to turn insights into improvements
Your Qualifications
- 3+ years of experience in data analysis or applied ML in a product context
- Strong SQL skills (PostgreSQL) and experience working with production data models
- Basic understanding of ML concepts: scoring, ranking, embeddings, LLM evaluation
- Python skills for data analysis (pandas, scikit-learn, etc.)
- Ability to communicate findings clearly — to engineers and to management
Nice to have
- Experience in HR tech, recruiting, or adjacent domains
- Familiarity with LLM evaluation methods
- Experience with analytics tools (PostHog, Metabase, etc.)
