Senior Software Engineer, Research

About Us

, We’re Building the Most Impactful Healthcare Company on Earth. We believe that access to a great doctor is a basic human right. Today, that’s not a reality. Delays, misdiagnoses, administrative chaos, and burnout plague the system.

One Human, One Doctor.

We enable our customers to staff 30% of their workforce with AI by creating a shared agent architecture for scale and efficiency. All powered by our own patented, world-class models and deployed in real-world care.

• Build and optimize core research infrastructure: evaluation pipelines, agent workflows, hallucination detectors, coding benchmarks, and research→production integrations.
• Design, implement, and scale agentic systems across backend, frontend, and model integrations, collaborating closely with research and co-founders.
• Own reliability, observability, and performance across agents (logging, tracing, instrumentation, safety checks).
• Ship research-proven features into production within 7 days, end-to-end.
• Develop shared tools, SDKs, and internal products that accelerate iteration across Research, QA, and Engineering.

• Senior-level full-stack engineering experience in React, Type Script, and Node.js.
• Proven ability to design, ship, and scale LLM-powered applications.
• Expertise in API design, streaming, and CI/CD pipelines.
• Strong cloud infrastructure background (AWS, GCP, or Azure).
• Track record of building reliable systems with measurable performance and error budgets.

• Audit all cross-agent flows for UI/UX consistency, correctness, and performance gaps.
• Implement shared components, typed schemas, and contract-driven interfaces for reliability.
• Establish instrumentation for frontend performance, agent consistency, latency, and model round-trip tracing.
• Improve or replace brittle evaluation or agent pipelines identified during onboarding.
• Partner with Research to product ionize at least one new capability.

• Deliver production-grade agentic workflows with
