Head Of Engineering

We're hiring a Head of Engineering to own the technology end to end. You will be the senior-most technical leader for Elyx, responsible for architecture, delivery, reliability, security and healthcare-grade compliance, and the engineering team. This role builds the engineering capability that lets Elyx find what works efficiently: high-throughput prototyping, instrumented so the team learns from what clients do, not only from what they say. You'll set technical direction, hire and grow the team, and stay hands-on in the hardest technical and architectural decisions. This is a high-ownership role for someone who has built complex, AI- and data-driven systems before and wants to do it in a domain that matters. The work is held to two standards at once: it has to be sound, and it has to change what a client actually does. Sound means evidence-based and reasoned from mechanism—and, because no two clients are the same, tested against the individual rather than assumed from the population. Key Responsibilities Own the architecture, delivery, reliability, and security of Elyx. You will collaborate with the product team to understand user needs, set the engineering roadmap, and lead the team of engineers to execute the roadmap in a timely manner. You will also be responsible for building an engineering culture leveraging the changing AI landscape. The core components of the Elyx product are: The reasoning engine. Elyx runs continuously across everything known about a client—labs, biomarkers, wearable streams, imaging, meal photos, self-reports. The engine identifies the real patterns in one client's noisy data while excluding the false ones, and monitors and validates the evolving scientific literature for the findings relevant to that client. The econometric search engine. This is the module to use the client’s medical and health telemetry to search against the pool of scientific knowledge, biased by the client’s preferences, to generate a list of interventions and diag…
