Senior ML Data Engineer

This fast-growing, well-funded health-tech company is on a mission to transform how clinicians understand and treat complex diseases. By combining advanced multimodal AI with real-world clinical data, they are building next-generation tools to help medical professionals see the full picture of a patient’s condition — from imaging to genomics to treatment history.

Working in close collaboration with leading hospitals and research institutes across Europe, the company has doubled in size over the past year to 80+ team members from more than 25 nationalities, with offices in Zurich and Amsterdam.

About the Role

As a Senior Data Engineer, you’ll be at the heart of building large-scale, high-quality datasets that power state-of-the-art foundation models for healthcare. You’ll design and implement advanced data pipelines for sourcing, generating, and curating complex multimodal datasets at massive scale.

You will:

• Build high-throughput pipelines to ingest multimodal data at petabyte scale.
• Develop systems for synthetic data generation to enhance model training.
• Create filtering and rating systems for topic relevance, quality, and compliance.
• Partner closely with ML researchers to steer the development of cutting-edge AI models.

What We’re Looking For

Essential Skills & Experience

• Excellent Python programming skills.
• Strong experience with distributed computing frameworks (Ray, Spark, or similar).
• Proven track record in designing and operating large-scale data pipelines.
• Hands-on experience with synthetic-data pipelines for LLMs.
• Deep familiarity with modern data architectures (Delta, Iceberg) and columnar formats (Parquet, ORC).
• Expertise in core data-processing techniques (hashing, deduplication, chunking) and related performance trade-offs.
• Strong communication skills for presenting technical concepts and experimental results

If you have a passion for building world-class data infrastructure and want to work on AI that genuinely helps people, I'd love to hear from you.

Following your application, Jay Robins, a specialist AI recruiter will discuss the opportunity with you in detail.
