Clinical Physician (Full-time or Part time)

Optexity is a product-driven research lab building clinical reasoning and computer use models on data no other lab can reach. We deploy directly inside clinics and hospitals including systems with no APIs using integration infrastructure weve built and open-sourced and in return become their preferred partner. That gives us proprietary clinical reasoning trajectories from practicing physicians and a feedback loop between real patient encounters our models and the products built on top of them.

Were a small fast-moving founding team with multiple published papers in NeurIPS ICML CVPR and backgrounds from Apple Amazon Microsoft CMU and IIT.

We are backed by world-class investors and leaders including Jeff Dean Neotribe VC PearVC Together Fund and Zapier Fund.

• Customer obsession we start with the customer and work backwards

• Intellectual honesty ideas matter more than titles; we communicate directly and assume good intent even in disagreement

• Bias for action we build and learn with customers rather than debate in the abstract

• Extreme ownership we own outcomes not just tasks and see problems through

Were building a clinical AI assistant that sits inside real practices surfacing care gaps assembling pre-visit prep flagging risk and suggesting treatment plans. None of that works without physicians defining what correct means.

Most clinical advisor roles are a monthly call where someone reacts to a demo. This one isnt. Youll be in the product loop weekly: deciding what the assistant should flag what a good summary actually looks like at 7:50am before a 15-minute visit and grading where the model is wrong and why. Your judgment becomes our ground truth and our evaluation standard.

Were looking for physicians across internal medicine cardiology oncology and other specialties both to go deep in your own domain and to help us understand where workflows diverge across specialties.

• Define what the assistant should surface. Which care gaps matter which risk signals are worth an interruption and which are noise that erodes trust. Translate clinical shorthand into precise checkable criteria.

• Shape the pre-visit summary. What belongs in it in what order at what length and what a physician actually reads versus scrolls past.

• Specify clinical search. What youd want to pull from the chart before a visit how youd phrase it and what a complete answer looks like.

• Judge the AI. Review model-generated risk flags differentials and treatment plans against your own reasoning. Score them explain the gap and tell us whether a miss is dangerous or merely different.

• Build ground truth. Help us construct real-case evaluation sets and rubrics that reflect actual standard of care not textbook answers.

• Pressure-test the product. Sit in on design decisions and tell us when something wouldnt survive contact with a real clinic day.

• Contribute to publications. We publish benchmarks and technical reports; clinical co-authorship is available and encouraged.

• MD or DO board-certified or board-eligible

• Currently practicing or recently practicing active clinical context matters more than titles

• Internal medicine cardiology oncology or an adjacent specialty; primary care and multi-specialty experience especially welcome

• Day-to-day fluency in an EMR (Epic eClinicalWorks Athena ModMed or similar) and an honest view of where it fails you

• Opinionated about clinical workflow and able to explain why something is right not just that it is

• Comfortable with ambiguity direct feedback and being asked how do you actually know that

• Genuinely interested in AI in medicine including its failure modes

• Clinical informatics training or CMIO-adjacent experience

• Experience with quality measures and value-based care programs (HEDIS MIPS CPT Category II HCC coding)

• Prior work advising or building health tech products

• Research or publication background

• Experience training residents or fellows the skill of articulating clinical reasoning out loud transfers directly

• Part-time: 515 hours/week flexible around clinical schedules. Async-friendly with a recurring weekly working session.

• Full-time: for physicians ready to step into a founding clinical role and own clinical direction end to end.

Remote is fine. Occasional in-person time in San Francisco or at partner clinic sites is a plus.

• Direct daily work with the founders no layers between your input and what ships

• Real influence over a product that practicing physicians will use not a pilot that dies in committee

• Competitive hourly rate for part-time engagements; competitive salary and meaningful equity for full-time

• Co-authorship on benchmarks and technical reports

• Visa sponsorship available for full-time roles
