About the Role
We are seeking a Head of Engineering, Decision Support to lead the productization of ML/LLM models in mission-critical healthcare contexts. This role will own the design and delivery of decision support systems that are reliable, explainable, and trusted by clinicians. You will build and scale a team focused on inference pipelines, observability, and safety while ensuring measurable improvements in throughput, latency, and quality. As a technical leader, you will work cross-functionally with leadership, compliance, and integration teams to ensure our AI-driven decision support delivers real-world clinical impact.
Key Responsibilities
Lead the productization of ML/LLM-powered decision support systems with strict quality, safety, and latency benchmarks.
Build and scale engineering teams with a strong observability and reliability culture.
Design and launch inference pipelines with fallbacks, caching, A/B evaluation, and rollback capabilities.
Collaborate with clinicians, compliance experts, and cross-functional leaders to ensure interpretability, auditability, and clinical trust in deployed systems.
Drive innovation in agentic workflows (e.g., recommendations, triage, treatment support) that balance automation with safety.
Hard Requirements
Proven leadership in shipping ML/LLM systems with measurable quality, latency, and reliability outcomes.
Deep experience in decision support contexts, including agentic or recommendation systems.
Expertise building production-grade inference pipelines with safety, caching, and evaluation frameworks.
Exceptional communicator able to align technical and clinical stakeholders.
Team builder with a track record of establishing observability-first engineering practices.
Nice-to-Have
Familiarity with healthcare data standards (FHIR, HL7) and clinical reasoning patterns.
Experience working with EHR integrations and compliance-sensitive systems.
Background in explainable AI, interpretability, or audit trails for clinician-facing tools.
First-Month Focus
Audit existing decision support infrastructure and identify reliability/latency bottlenecks.
Establish engineering standards for observability, fallbacks, and A/B evaluation pipelines.
Partner with the EHR Integrations team on upcoming FHIR-driven workflows (Q4 2025).
Success OKRs (90 Days)
Launch and monitor production inference pipelines with measurable improvements in latency and throughput.
Deliver first decision support use case with clinical interpretability and audit features enabled.
Hire and onboard core engineering talent to scale decision support initiatives.
Culture Fit
Persistent, driven problem solver
Willing to push back on leadership to defend quality/timelines
Thrives in high-ambiguity, fast-paced startup environments
