We believe AI agents should handle these workflows-scheduling, billing, prescription refills, and follow-ups-so healthcare teams can focus on actual patient care.\nWe’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.\nClarion 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.\nWhy This Role Is Special\nReal traction, early-stage impact: Dozens of paying customers, rapidly growing revenue, and the chance to shape core systems at an inflection point.\n\nMission-critical problem: Healthcare communication failures affect millions daily-your work directly improves patient access and outcomes.\n\nElite technical context: Work closely with founders who deeply understand both healthcare operations and advanced AI systems, enabling fast decisions and real ownership.\n\nWhat You’ll Own\nLead the deployment, performance, and reliability of AI agents operating in live, high-stakes healthcare environments.\n\nArchitect and scale full-stack systems integrating with EHRs, legacy healthcare platforms, and real-time voice infrastructure.\n\nDrive technical strategy for customer-facing solutions, collaborating with product and engineering to translate client needs into scalable architecture.\n\nMentor engineers and set standards for code quality, testing, security, and HIPAA-compliant development.\n\nShape product roadmap by identifying systemic challenges in customer workflows and proposing high-leverage technical solutions.\n\nInteresting Technical Challenges\nGenerative AI at Scale: Design and operate production systems using LLMs with rigorous safety, alignment, and real-time monitoring at enterprise scale.\n\nReal-time voice infrastructure: Build ultra-low-latency systems supporting thousands of concurrent calls with 99.99% uptime.\n\nFragmented healthcare systems: Design resilient abstraction layers across modern APIs and legacy platforms while maintaining security and compliance.\n\nHighly Personalized Experiences: Develop adaptive AI that retains patient context across sessions, personalizes tone and flow, and delivers conversations indistinguishable from human care.\n\nWhat We’re Looking For\n5+ years of experience designing, building, and scaling production systems in high-reliability environments.\n\nStrong full-stack expertise with Node.js, TypeScript, React, and PostgreSQL, plus solid system design instincts.\n\nHigh ownership and agency-you thrive in ambiguity and take responsibility for outcomes.\n\nProven ability to mentor engineers, lead cross-functional efforts, and communicate technical trade-offs clearly.\n\nYou’ll be a great fit if you enjoy owning complex systems end-to-end, solving hard problems under real-world constraints, and working closely with customers and teammates to deliver mission-critical software.\nInterview Process\nWe move quickly and communicate clearly at every stage:\nIntro Chat (30 min, Virtual): Background, role context, and leadership philosophy.\n\nTechnical Deep Dive (1 hr, Virtual): System design and architecture with the CTO and a senior engineer.\n\nOnsite Team Day (Half Day, NYC): Collaborate on real problems, present a past project, meet the team, and assess mutual fit.\n\nDecisions are typically made within 24 hours of each stage.","description_format":"text","description_chars":3948,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Health
