Full-Stack Engineer - Clarion : Job Details

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 drowns in administrative tasks. We believe AI agents should handle these workflows-scheduling, billing, prescription refills-so healthcare teams can focus on actual patient care. We're building the communication infrastructure that modern healthcare desperately needs. Our AI agents don't just answer calls; they complete entire workflows end-to-end, giving providers back their time and ensuring patients never go unheard. We've already handled hundreds of thousands of patient interactions across virtual care companies, health systems, and a $5B health insurance company. Founded by a Stanford/Harvard-trained physician who built Two Chairs and Ophelia, and an ex-Amazon Alexa engineer who led AI/ML at Salesforce, we uniquely understand both the clinical and technical challenges of transforming healthcare communication. We've raised $5.4M from Accel, Y Combinator, Sequoia (scout), and healthcare founders from Ophelia, Medallion, and Counsel Health. We're an in-person team based in New York, moving fast to ensure no patient call goes unanswered. Why Join Us?

• Early-stage with strong market validation: We have dozens of paying customers with rapidly growing revenue and strong market signals, while offering the high-impact environment of an early-stage startup.
• Solving a massive healthcare challenge: We're addressing a critical problem in healthcare communication that affects millions of patients and providers daily, with technology that can truly transform the patient experience.
• Technical founding team: You'll work directly with experienced founders who deeply understand both healthcare operations and technical development, enabling faster decision-making and better product outcomes.
• Cutting-Edge Tech Frontier: You'll harness the latest generative AI models-LLMs, voice synthesis, and real-time transcription-to craft conversational agents that transform healthcare communication, while driving innovation to push these technologies beyond their current limits.
• In-person collaboration advantage: We've built in-person since day one and maintain this as a strategic advantage-we move faster, build stronger bonds, and create a cohesive culture.

What you'll be working on

• Embed with customer teams to deploy and optimize AI agents in live healthcare environments.
• Collaborate with engineering and product teams to customize solutions based on client feedback.
• Troubleshoot and iterate on healthcare integrations to ensure seamless performance.
• Drive customer success through onsite training, support, and relationship management.
• Contribute to product roadmap by identifying real-world challenges faced by customers

Requirements

• Technical excellence: 3+ years of engineering experience, with a proven track record of shipping production systems.
• Healthcare systems experience: Familiarity with healthcare workflows, EHR integrations, or regulated environments (HIPAA compliance is a plus).
• Full-stack engineering skills: Deep expertise in our tech stack (Node.js, TypeScript, React, PostgreSQL), with the ability to build reliable integrations and debug complex systems.
• High agency and ownership: Comfortable in ambiguous situations, making independent decisions, and taking full responsibility for customer success.

You are a good fit if

• You build with intensity and excellence-shipping solid code fast, tackling tough problems from start to finish, and holding steady under pressure.
• You take full ownership of your work, acting with high agency in unclear, shifting situations.
• You bring technical passion and a team spirit-driven to solve hard challenges and lifted by working closely with customers and teammates.

Interesting Technical Challenges

• Generative AI at Scale: Deploy at-scale production systems using generative AI models, tackling safety, alignment, and real-time monitoring.
• AI for Healthcare Conversations: Build voice agents that understand medical terminology, navigate complex clinical workflows, and make real-time decisions with accuracy comparable to trained medical staff.
• Real-time Voice Infrastructure: Create a system that processes speech in milliseconds, handles multiple concurrent calls, and maintains high availability for mission-critical healthcare communications.
• Integration with Fragmented Systems: Connect seamlessly with diverse healthcare platforms-from modern cloud APIs to decades-old legacy systems-creating a unified communication layer.
• Highly Personalized Experiences: Develop AI that remembers patient preferences, adapts to individual communication styles, and creates natural conversations that feel remarkably human.

What we offer

• Transformative impact: Build technology that directly improves healthcare for millions-your code will liberate medical staff from administrative burden and give patients seamless access to care
• Growth trajectory: Join our founding team, grow into leadership, build your team, and shape the technical direction of a rapidly scaling company
• Technical frontier: Work at the bleeding edge of AI and voice technology, solving problems most engineers never get to tackle
• Career opportunity: Position yourself at the convergence of healthcare and conversational AI, building solutions that healthcare organizations desperately need
• Exceptional compensation: Competitive salary, meaningful equity, and comprehensive benefits including 100% covered healthcare, flexible time off, 401(k)

Interview Process At each stage, we decide within 24hrs and update you shortly after:

• First Chat (30 min) [Virtual]: A casual conversation about the role and your experience to see if there's a good initial fit.
• Technical Assessment (1 hr) [Virtual]: Work through a system design exercise with our CTO.
• Team Day (Half-day) [In-Person]: Visit our New York office to meet the team, collaborate on real engineering challenges, and see if we're a good match for each other.

If you're ready to transform how millions of patients connect with their healthcare providers, we'd love to hear from you.
