Software Engineer (Fullstack)

Job description

## 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.
