Software Engineer (Fullstack)

About Clarion

At Clarion, we’re rebuilding how healthcare communicates in the age of AI.

Today, clinics miss 30–40% of patient calls, while staff are overwhelmed by administrative work. We believe AI agents should handle workflows like scheduling, billing, prescription refills, and follow-ups so healthcare teams can focus on patient care.

We’re building the communication infrastructure modern healthcare needs. Our AI agents don’t just answer calls—they complete workflows end-to-end, ensuring patients never go unheard. To date, we’ve handled hundreds of thousands of patient interactions across virtual care companies, health systems, and a $5B health insurance company.

Clarion was founded by a Stanford/Harvard-trained physician (founding team at Two Chairs and Ophelia) and an ex-Amazon Alexa engineer who led AI/ML teams at Salesforce. We’ve raised $10M from Accel, Y Combinator, Sequoia (Scout), and leading healthcare founders. We’re an in-person team in New York, moving fast to solve one of healthcare’s most critical problems.

WHY THIS ROLE IS SPECIAL

• High-impact ownership: You’ll own meaningful features and systems used daily in real healthcare environments.

• Strong signal, early traction: Dozens of paying customers and growing revenue, with room to shape core product decisions.

• Learn from experienced builders: Work closely with founders and senior engineers operating at the intersection of healthcare, AI, and real-time systems.

What You’ll Work ON

• Build and operate production full-stack features powering AI-driven healthcare communication.

• Integrate with EHRs, legacy healthcare systems, and real-time voice infrastructure.

• Collaborate closely with product, design, and senior engineers to turn customer needs into shipped software.

• Debug and improve reliability, performance, and scalability across live systems.

• Contribute to technical discussions, code reviews, and evolving engineering best practices.

• INTERESTING TECHNICAL CHALLENGES

• AI-powered workflows: Support and extend LLM-driven systems used in real-time healthcare interactions.

• Real-time systems: Work on low-latency services that process live voice and patient data.

• Healthcare integrations: Build resilient abstractions across fragmented, regulated systems while maintaining security and compliance.

What We’re Looking FOR

• 3–5 years of experience building and shipping production software.

• Strong full-stack experience with Node.js, TypeScript, React, and PostgreSQL.

• Comfort working in ambiguous environments and learning quickly.

• A strong sense of ownership—you care about quality, reliability, and real-world impact.

• Clear communication and a collaborative mindset.

• You’ll be a great fit if you enjoy shipping real software, learning from experienced teammates, and growing your technical judgment while working on meaningful problems.

• INTERVIEW PROCESS

• We move quickly and communicate clearly at every stage:

• Intro Chat (20–30 min, Virtual): Background, role context, and mutual fit.

• Technical Interview (1 hr, Virtual): Practical system design and coding discussion with an engineer.

• Onsite Team Day (Half Day, NYC): Collaborate on real problems, meet the team, and assess mutual fit.

• Decisions are typically made within 24 hours of each stage.
