• AI adopter — comfortable with parallel pipelines and agentic tooling, and understands that good agents come from systems-thinking, testing, and validation, not just code generation
• Experience building performant microservices with frameworks like Express or NestJS
• Familiarity with MongoDB or another NoSQL database, including common design patterns and trade-offs
• English level - at least Upper-intermediate and higher

About You

• Product-minded and user-obsessed

• Enhanced parental leave (maternity, paternity, adoption)
• A MacBook and everything you need to do your best work

• Design, build, and maintain scalable, reliable AI systems.
• Drive technical decisions and provide context-aware solutions for AI systems in biological research.
• Leverage and pioneer evaluation methodologies to ensure continuous product improvement.
• Experiment with cutting-edge industry solutions—orchestration patterns, fine-tuning, specialized monitoring, feedback loops, etc.
• Lead core stack component development focusing on sustainability, scalability, security, reliability, and performance.
• Foster team growth by sharing expertise and mentoring colleagues through code reviews, technical discussions, and knowledge sharing.
• Participate in a team wise shared on-call rotation.

Example Of Scope

• Lead Agent Development: Drive the development of Owkin agents and actively contribute to the core components of our platform, "K-Pro."
• Optimize Analytical Workflows to feed the agents with the data they need when they need it — e.g. analytical DBs (DuckDB), distributed computing (AWS Athena, Trino, etc), integration with data platforms (Snowflake, Databricks, etc).
• Deployment and Integration: Manage the seamless integration and deployment of agents within Owkin's broader Data Platform infrastructure.

About You
Required qualifications / experience:

• You’re driven by impact — excited to empower biomedical researchers with intuitive, AI-driven tools that unlock scientific discovery.
• Strong collaborative skills with an open, pragmatic mindset; you thrive in multidisciplinary environments that involve people with diverse backgrounds.
• Clear and effective communicator who can translate technical complexity into actionable decisions for the team.
• Deep understanding of system architecture, infrastructure design, and building resilient distributed systems - including complex analytical workflows.
• Extensive experience with production environments: continuous deployment, high availability, observability, and security.
• Curiosity and ideally hands-on experience with AI systems — from integrating LLMs to evaluating their performance in real-world workflows.
• Passion for user experience and product thinking: you consider not only the system’s internals but how the end user interacts with and benefits from your work.
• Proficiency with Claude Code and other AI software engineering tools
• Fluent English, both written and spoken.
• Stack: Python, Kubernetes, AWS

Preferred Qualifications/bonus

• Experience working with spatial transcriptomics data.
• Knowledge of different technologies for distributed computing, databases, and serialization.
