Research Engineer / Research Scientist, Health

We are seeking an exceptional, hands-on researcher who wants to build frontier health capabilities and turn them into impact at scale. As a Research Engineer / Research Scientist, Health, you will own a high-leverage research direction end to end,from deciding which problem matters and how to measure it, to designing and running experiments, to integrating successful work into frontier models.

The Health team, within OpenAI’s broader Personal AGI organization, has a mission to ensure AGI improves health for all humanity. Improving human health will be one of the defining impacts of AGI. Hundreds of millions of people already turn to ChatGPT for questions about their health and millions of clinicians use it weekly to support care delivery.

Responsibilities:

• Own a high-leverage research direction end to end,from deciding which problem matters and how to measure it, to designing and running experiments, to integrating successful work into frontier models.
• Develop scalable methods across pretraining, midtraining, reinforcement learning, and post-training to improve health reasoning, knowledge, reliability, calibration, and behavior.
• Build and study RL environments grounded in real health problems; understand which data and training setups produce robust, generalizable improvements rather than just higher benchmark scores.
• Create meaningful, trustworthy, and unsaturated evaluations that tell us whether our models are actually getting better at what matters for patients and clinicians.
• Advance new 0→1 capabilities in health that may have an increasing impact with upcoming increases in model intelligence and test-time compute.
• Develop models and agents that can work over longitudinal, multimodal health data to produce useful predictions, surface new scientific insights, and support better individual- and population-level decisions.
• Work closely with researchers, engineers, clinicians, and product teams to bring health capabilities into the models and products used by hundreds of millions of people.
• Help establish that AI improves real health outcomes, not just that it can produce impressive answers or demos.

Requirements:

• Care deeply about using increasingly capable AI to improve human health, and take seriously the responsibility of deploying it safely.
• Have an unusually strong track record in machine learning or AI research, with the depth to push at least one important area forward: pretraining, reinforcement learning / post-training, evals (not necessarily specific to health); or substantial depth in a relevant frontier health / biomedical AI problem.
• Are a hands-on builder: you can design experiments, write and debug code, work directly with data and training infrastructure, and move quickly from an idea to evidence.
• Have strong research taste and can distinguish an important problem or a promising approach from an interesting one.
• Own ambiguous problems end to end, and are willing to learn whatever is missing to get the job done.
• Stay goal-oriented rather than method-oriented, and don’t shy away from unglamorous work if it is the highest-leverage path to impact.
• Care about whether a capability will scale, generalize, and make it into the real world,not just whether it can be shown in a paper or prototype.
• Enjoy working with low-ego, ambitious people across research, engineering, medicine, and product.

Benefits:

• Medical, dental, and vision insurance for you and your family, with employer contributions to Health Savings Accounts
• Pre-tax accounts for Health FSA, Dependent Care FSA, and commuter expenses (parking and transit)
• 401(k) retirement plan with employer match
• Paid parental leave (up to 24 weeks for birth parents and 20 weeks for non-birthing parents), plus paid medical and caregiver leave (up to 8 weeks)
• Paid time off: flexible PTO for exempt employees and up to 15 days annually for non-exempt employees
• 13+ paid company holidays, and multiple paid coordinated company office closures throughout the year for focus and recharge, plus paid sick or safe time (1 hour per 30 hours worked, or more, as required by applicable state or local law)
• Mental health and wellness support
• Employer-paid basic life and disability coverage
• Annual learning and development stipend to fuel your professional growth
• Daily meals in our offices, and meal delivery credits as eligible
• Relocation support for eligible employees
• Additional taxable fringe benefits, such as charitable donation matching and wellness stipends, may also be provided.
