- Build GDPR compliant systems: encryption, data governance, privacy-by-design across all features.
- Execute our ML/AI roadmap: behavioral models, EU-based LLM integration, chatbot fine-tuning, and MLOps deployment.
- Implement experimentation infrastructure: A/B testing, analytics pipelines, data-driven decisions.
- Recruit, onboard and mentor a Data Scientist, ML Engineer, two Software Developers, UX/UI designer, and Behavioral Scientist.

- Experience with product analytics, A/B testing, multi-tenant architectures, or real-time communication systems. You don’t need all of these, but familiarity with several is valuable.
- Strong GDPR/privacy expertise: privacy-by-design, encryption, data governance.
- Strong communicator: explain technical decisions to both engineers and non-technical stakeholders.
- Pragmatic decision maker: you balance innovation with startup constraints and choose “good enough” over “perfect.”

What we offer

- A fulltime position (36 hours per week).
