Job description

  • Direct impact on an AI product in daily production use
  • Access to real production data and immediate user feedback
  • Close collaboration with the engineering lead
  • Remote-first, data-driven culture

Ihre Aufgaben

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

Requirements

  • 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.)
