THE ROLE

We’re looking for a Data Scientist to help us understand and optimize how our marketplace performs and how our talent behaves, from first touch to long-term retention.

You’ll sit within a centralized Analytics & Data Science team but cross-functionally work across Marketing, Sales, Product & Engineering, and Ops. Your job is to bring clarity: defining the right metrics, building reliable data models, and turning complex analyses into decisions that move the business forward.

This role covers three core areas

• Marketing effectiveness: how channels and campaigns contribute to growth

• Talent lifecycle: understanding user behavior from acquisition and activation through retention and lifetime value

• Marketplace performance: how supply and demand interact across our platform

WHAT YOU WILL BE DOING

• Define and maintain key metrics across the marketplace and user lifecycle, supported by reliable dbt models that teams can trust.

• Build self-service dashboards, reporting layers, and playbooks that make data accessible and actionable across internal teams.

• Develop attribution and measurement models (multi-touch attribution, data-driven attribution, Marketing Mix Models) to understand channel contribution to acquisition and engagement.

• Model talent behavior including conversion, retention, and Customer Lifetime Value to help the business focus on sustainable marketplace growth.

• Design and analyze experiments (A/B tests, incrementality tests) to measure the causal impact of marketing and product changes.

WHAT YOU BRING

• 4+ years of experience in analytics, data science, or marketing science/analytics, ideally in a marketplace or platform business

• Expert-level SQL and strong experience with dbt or similar transformation tools

• Proficiency with BI and visualization tools/frameworks (e.g., Metabase, Tableau, Streamlit)

• Deep understanding of digital marketing ecosystems (e.g. Google, Meta, TikTok, CRM tools like Salesforce)

• Hands-on experience with attribution modeling, experimentation, and performance measurement

• Python experience is a strong plus, especially for statistical modeling

• AI-first mindset, leveraging modern AI tools to improve workflows and impact

• High ownership: proactively identifying problems and driving solutions end-to-end

WHAT WE OFFER

• Innovative mission: Together we create something new. Work in a dynamic set-up where you learn a lot and your every idea is heard.

• Unique team spirit: We can rely on each other blindly and celebrate all successes together as a team.

• Vacation: Recreation and further education is important, which is why we offer 28 days of paid vacation (increased by 1 day for every 2 calendar years of service with us, up to a maximum of 30 days), 1 day of special leave for community service, 5 days of paid educational leave, and the possibility of unpaid leave

• Hybrid working model: We love our brand new office in Prenzlauer Berg. But sometimes you need a little more flexibility. Zenjob’s flexible working model combines the best of both worlds, so you can work remotely up to 2 days / week (1 day, during the first 6 months, so we can guarantee you the best onboarding).

• Dog-lover: If you have a dog, feel free to bring it with you. We don’t bite and always have a bowl of water in our range of drinks

• Personal growth: Ongoing focus on your personal development (annual training budget of EUR 750, mentoring opportunities, constant career development conversations)

• Healthy mind in a healthy body: With us you will receive a 30 EUR Urban Sports Club grant to keep you fit. In addition, we have a small sports room in the office ourselves.

• Always mobile: You will receive EUR 40 credit per month for NAVIT, https://www.navit.com/ a sustainable mobility tool for public transport, bike sharing and much more.

• Legendary Events: Quarterly team events, winter and summer parties, budget for birthdays and anniversaries of our employees
