  • Build scalable, reliable systems for LLM orchestration, grounding, evaluation, and agent-like workflows.
  • Create reusable frameworks and patterns that other engineering teams can adopt across the company.
  • Drive multi-quarter technical initiatives and help bridge AI research prototypes with production-grade systems.
  • Partner closely with Product across multiple verticals
  • Work with Pharmacy, E-commerce, Care, and Operations to bring AI-powered features to life, from patient-facing journeys to internal efficiency tools.
  • Collaborate on product strategy, helping translate ambiguous ideas into clear technical plans.
  • Support teams in releasing features quickly through incremental, high-velocity delivery cycles.
  • Ensure user-facing AI experiences meet expectations for performance, reliability and usability.
  • Champion safety, privacy, and clinical integrity
  • Develop evaluation frameworks and observability systems that measure AI behavior, grounding, safety, and quality.
