• End-to-end delivery ownership from strategic requirements through operational deployment.

Technical:

• Expert in Python and SQL; strong software engineering practices.
• Deep experience with AWS, Azure, or GCP data/AI platforms.
• Strong understanding of distributed systems, cloud-native architecture, MLOps, platform engineering.
• Hands-on with vector DBs, embeddings, retrieval systems, RAG.
• Experience with CI/CD, orchestration, IaC/automation, observability.

Leadership & Communication:

• Exceptional written/verbal communication.
• Able to translate complex AI/data architecture concepts into mission impact, risk, and tradeoffs.
• Demonstrated ability to influence and drive consensus across stakeholders.

What we'd like you to have

• Prior roles as Principal Engineer, Lead Data Engineer, Solutions Architect, Technical Lead.
• Built/operated enterprise vector search/knowledge management / RAG / LLM platforms.
