[Hiring] Member of Technical Staff, Compiler @deCircle

Role Description

Research role with production stakes: study how far frontier models can be pushed in extracting, structuring and proving clinical logic, design the experiments that settle what works, and ship the winning approach into the clinical compiler, which is live in Canadian public health care today. Ideal for someone who has published in clinical AI, wants out of the demo cycle, and believes clinical decision logic must be inspectable.

What you'll do

• Build the pipeline converting clinical standards into executable modules: parsing with document and layout models, transformation, validation
• Design and iterate the target syntax/representation for guideline logic (exclusions, precedence, recommendations)
• Run experiments: open vs closed models, fine-tuning, constrained decoding
• Co-design benchmarks and adversarial cases measuring source fidelity, logical completeness and recommendation correctness; error analysis
• Develop deterministic validators using static analysis, constraint solving or formal methods to surface ambiguity, contradiction and source silence
• Work directly with the founders and the clinicians who validate the outputs; turn model failures into hypotheses and better system design

Qualifications

• 3+ years of research or industry experience, or final-year PhD / postdoc
• Published in clinical AI (strongly preferred)
• Python, PyTorch, Transformers/LLMs; static analysis, SMT/SAT solvers; FHIR / HL7 v2 a plus
• US or Canada based; US citizen/Green Card (visa exceptions possible for frontier-lab employees)

Requirements

• Compensation: $250,000-$400,000 base + competitive equity (up to 5% for a frontier-lab candidate, from a 15% pool; cash/equity ratio flexible)
• Health, dental, vision, flexible PTO, paid parental leave
• Location: Remote - US or Canada, with offsites several times a year
• Visa: not open to visas (possible exceptions for frontier-lab employees)

Benefits

• Health, dental, vision
• Flexible PTO
• Paid parental leave
