• Own agent orchestration, tool use, memory, and retrieval patterns, choosing between hosted and self-managed models based on safety, cost, and latency.
• Stay current on advances in LLMs and agentic systems and translate them into a practical roadmap.
• Establish guardrails so agent responses stay within approved product and regulatory claims, including no unapproved dosing or treatment advice.
• Build evaluation frameworks with clinically grounded test sets, co-owned with data science and clinical teams, covering accuracy, safety, and user impact.
• Ensure every agent response is traceable and auditable in line with design controls and regulatory requirements.
• Partner with regulatory and quality teams on risk analysis, documentation, and evidence for AI-enabled features.
• Use sound judgement and discretion when handling confidential and personal health data.
• Provide technical leadership and mentorship across the AI engineering team and lead architecture and design reviews.
• Productionize time-series and personalization models for glucose insights, from prototype to scalable, monitored services.
• Build batch and real-time inference services with defined latency, cost, and availability targets.
