Head of Data Science

What you'll do

Leading people

• Hire, onboard and grow the data science team. We're hiring several data scientists right now, and you'll shape who joins and how they ramp up.
• Build a team culture that matches our values: a high bar for quality, full ownership of outcomes, and kindness towards each other
• Lead and inspire the team through regular 1:1s, actionable feedback and clear career paths

Leading the technical work

• Set the technical direction and roadmap for data science, together with product and engineering leadership, and decide what the team works on and what it doesn't
• Own quality in production with strong operational excellence and reproducibility across the ML lifecycle
• Drive innovation by investing in scalable machine learning data infrastructure
• Stay close to the work: review designs and code, and step in hands-on when it matters
• Represent data science to leadership and customers

What we're looking for

• 8+ years in data science or machine learning, including 3+ years managing data scientists or ML engineers as direct reports, ideally at a high-growth startup or an established tech company
• A track record of building great teams: hiring well, developing people, and creating the standards and rituals that make a team more than the sum of its individuals
• Experience taking ML products from research to production, and building the practices that keep them reliable: evaluation, monitoring, reproducibility
• A solid understanding of LLMs and strong instincts for measurement and statistics when outputs are noisy
• Strong technical depth to review architecture and modeling decisions, ideally in cloud-native environments (GCP a plus)
• Clear communication with executives, engineers and customers, including being honest about uncertainty
• Good judgment under ambiguity, and the ownership to deliver outcomes despite blockers

Our stack

A standard Python and SQL stack on GCP. We work with all the major LLM providers (OpenAI, Anthropic, Google, Perplexity) as well as open-weight models.

Bonus points

• Contributions to open-source projects or ML tooling
• Public side or research projects that show technical depth
• Publications or talks at ML or AI conferences
• Founder experience or senior technical leadership at a high-growth startup

What we offer

• A defining leadership role with real impact and ownership at one of Europe's fastest-growing Series A startups
• Regular team events and off-sites
• Aggressive equity compensation package
• Paid dinner & Uber home when working late
• The most beautiful office space and work environment in Berlin
