AutoScout24 Engine GmbH is looking for a Senior Data Scientist to be a key contributor within our global Data Science organization. You will shape AI and machine learning systems that sit at the core of our marketplace platforms across Europe and Canada, designing, building, and operating production systems that matter to the business.
What You'll Do
- Own ML and GenAI systems end-to-end in production, including problem framing, system design, deployment, monitoring, and continuous improvement.
- Make sound architectural and methodological decisions for ML systems on AWS, balancing robustness, observability, cost, and long-term maintainability.
- Partner closely with Product, Engineering, and Business leaders to turn ambiguous problems into ML-enabled product solutions with clear outcomes.
- Operate and evolve ML systems deployed across multiple countries and markets, accounting for differences in data distributions, regulations, and constraints.
- Mentor other data scientists through hands-on technical guidance, design reviews, and shared ownership of systems.
What We're Looking For
- Advanced degree in Computer Science, Engineering, Mathematics, or a comparable field.
- 5+ years of experience building and owning production ML systems end-to-end in a real-world environment.
- Strong hands-on expertise in Python and modern ML frameworks, with the ability to ship, operate, and evolve ML systems in production.
- Solid experience with AWS and MLOps practices, including deployment, monitoring, and operating ML systems at scale.
- Practical experience applying GenAI / LLMs in applied or production contexts, with a clear understanding of trade-offs and limitations.
- Ability to influence technical decisions through clear judgment and collaboration, not formal authority.
- Experience supporting and guiding more junior data scientists through hands-on collaboration, code reviews, and technical feedback.
- Strong sense of ownership and accountability for outcomes, with a pragmatic approach to trade-offs and delivery.
