Member of Technical Staff, Compiler

About the Role

Join a healthtech team building a production compiler that turns clinical standards into executable, traceable decision logic. This research-focused role combines experimentation with frontier AI models and engineering work that supports clinical use.

What You'll Do

• Build pipelines to parse clinical documents and transform their content into validated executable modules.
• Design and refine a target representation for clinical guideline logic.
• Evaluate open and closed models, fine-tuning approaches, and constrained decoding techniques.
• Develop benchmarks, datasets, metrics, and adversarial cases to assess clinical fidelity and logical completeness.
• Analyze model errors and use findings to guide experiments and improve the production compiler.
• Build deterministic validators using static analysis, constraint solving, or formal methods to surface ambiguity, contradictions, and missing source information.
• Collaborate with clinicians and company leadership to validate system outputs and guide development.

What We're Looking For

• At least 3 years of research or industry experience, or final-year PhD or postdoctoral experience.
• Experience shipping production engineering work and ML or NLP systems.
• A bachelor's degree or higher in computer science, machine learning, mathematics, or a related technical field.
• Production-level experience with Python, PyTorch, and the Transformers ecosystem, plus experience in LLM evaluation, training, or prompt engineering.
• Ability to communicate failed experiments and uncertainty clearly, and to validate model outputs rather than assume they are correct.
• Comfort working across disciplines in an ambiguous environment, with willingness to attend in-person offsites several times per year.
• Experience in compilers, program synthesis, formal methods, static analysis, healthcare, or another regulated or safety-critical domain is relevant.
• Knowledge of intermediate representations, constraint solving, SAT/SMT, domain-specific languages, FHIR, or HL7 v2 is useful.
