Principal Product Engineer - Evinova

AstraZeneca is seeking a Principal Product Engineer for their Evinova division. This hands-on technical leadership role involves designing and building AI-powered product features, mentoring engineers, and making key architectural decisions to ensure product scalability.

Responsibilities:

• Design and build AI-powered product features — agent architectures, RAG pipelines, model orchestration, evaluation frameworks, and guardrails — with the same engineering rigor as any production system: testable, observable, gracefully degrading
• Own the full stack for the features you build — application code, data, infrastructure — making end-to-end decisions about deployment, observability, cost, and security
• Make architectural choices that optimize for reversibility early and durability when the problem is actually understood
• Mentor and coach engineers on your team, transferring judgment and mental models, not just answers. Calibrate involvement to stakes: get out of the way for cheap-to-reverse work, lean in for load-bearing decisions
• Read existing systems as accumulated knowledge before treating them as debt. Understand why things are shaped the way they are before proposing changes
• Identify and manage the blast radius of technical decisions — the dangerous ones at this level aren’t bad deployments, they’re bad directions
