Founding Backend Engineer, AI Agents

Tivara

Tivara is building AI agents that take care of the complex, behind-the-scenes operations for large specialty clinics, allowing doctors to focus on delivering optimal care (not phone calls). Demand from clinics is already outpacing our capacity, and every feature you ship directly accelerates our growth.

We’re a 3 person founding team in New York City, backed by Y Combinator, Mischief VC, and Day One Ventures. If you’re excited about building ambitious technology that makes healthcare a frictionless experience, we’d love to talk.

The Role

As a founding engineer, you’ll be working directly with the CTO to design and build the core systems that power our AI agents. You’ll own entire features across the stack and help set the technical and cultural foundation of Tivara.

Some of the problems you might tackle: 

• Voice AI Architecture - Build the core platform connecting telephony, LLMs, and models to power thousands of low-latency patient ↔ agent conversations. You’ll be pushing the limits of Voice AI infrastructure in a fast-evolving space
• AI-Native Post-Call Workflows - Automate what happens after a call, from charting to scheduling. You’ll design evaluation frameworks and ship production-ready AI agents that form the backbone of our “agentic workforce.”

This is a true zero-to-one opportunity: your work will be foundational, highly visible, and directly tied to millions in revenue.

What We’re Looking For

• Builder mindset: You love shipping, iterating, and learning from real users.
• Collaborative Energy: You thrive in-person, working shoulder-to-shoulder with founders in our NYC office (5 days/week)
• Technical craftsmanship: You care about performance, reliability, and building systems that scale.
• Low-ego, high ownership: You’re kind, direct, and solutions-oriented.

Our Values

• Customer obsessed: We build with patient experience in mind.
• Extreme ownership: Things break, we fix them fast, no blame.
• Always learning: Our AI learns daily, and so do we.
• Enjoy the ride: We work hard and genuinely like being together.
