About the Company

We’re a stealth-mode, mission-driven startup transforming how healthcare is delivered through applied AI. Backed by experienced founders and tackling real-world inefficiencies in clinical workflows, we’re building agentic AI systems that automate doctors’ administrative tasks, reduce misdiagnosis, and enhance patient outcomes at scale.

What You’ll Do

As a Senior Full Stack Engineer and early technical leader, you’ll work directly with the founding team to shape core infrastructure, implement AI-driven solutions, and lay the foundation for a product used by clinicians across the U.S.

• Lead by example with clean, testable code and mentor future hires.

• Own development of APIs, documentation, and backend architecture.

• Drive implementation of security and data protection protocols.

• Collaborate with product and AI teams to integrate cutting-edge LLMs in production.

What We’re Looking For

• Proven experience building and scaling agentic AI systems (hands-on, not theoretical).

• Experience with LLMs, including fine-tuning and deploying in production-grade environments.

• Deep knowledge of at least one agentic framework (e.g., LangChain, AutoGen, CrewAI) and exposure to others.

• Experience at fast-moving startups and working across global teams.

• Strong communication and leadership instincts – you’ve led projects or small teams.

• Expertise in React and Python is a must.

• Bonus: Background in healthcare, ML, or data privacy/security.
