Founding Data Scientist

We're looking for a Founding Data Scientist to work directly with leadership on zero-to-one measurement and growth problems. This is not a role for maintaining existing systems - it's for someone who can take an ambiguous, high-stakes question and build the data infrastructure to answer it reliably, then own what comes next.

We value people who combine measurement rigour with builder instincts: someone equally comfortable designing a causal experiment and shipping the pipeline that operationalises its output.

What You'll Do

• Own incrementality testing across marketing, product, and rewards - proving its value from hypothesis to business impact.
• Build the data pipelines and measurement stack behind it, tying experiments to real shifts in user behaviour, monetisation, and multi-touch attribution.
• Drive experimentation strategy across growth and product: design, run, and interpret tests with a sharp focus on causal validity - not just p-values.
• Own data products end-to-end: scoping, architecture, implementation, rollout.
• Partner with C-level, engineering, and business stakeholders to turn measurement into live operational decisions.
• Set the frameworks and practices the team can scale on.

• Deep expertise applying causal inference and experimental design in practice, in real business contexts.
• Hands-on experience building and operationalising attribution models in a real business context - not just running models, but making them useful.
• Proven zero-to-one experience: ambiguous problem, built the infrastructure, shipped something production-ready.
• Proficiency in Python and SQL; GCP preferred; comfortable with modern data stack tools (dbt).
• Experience with programmatic advertising, ML pricing, or mobile measurement - MMPs, probabilistic attribution, or similar - is a strong plus.

You Are

• A builder with a strong ownership mindset - you don't wait for a spec.
• Rigorous but pragmatic: the stats matter, but the business question matters more.
• Someone who, if they have to debug something twice, automates it.
• A clear communicator - you can translate model outputs into decisions that non-technical stakeholders can act on.

• Own Our Growth: Competitive package with meaningful equity.
• High Impact: Work on company-defining projects, not tickets in a queue.
• Scale With Almedia: Join a profitable, high-growth startup early.
• Great Environment: Central Berlin office, transport subsidy, breakfasts and lunches, language learning, Urban Sports Club, and more.

At Almedia our mission is to engineer the future of user acquisition and revolutionize the advertising technology landscape.
