About the Company
Our client is an early-stage, venture-backed healthcare AI company building an AI nurse concierge for Medicare beneficiaries. They pair each patient with a dedicated healthcare advocate who handles appointments, insurance, and care coordination, while AI agents take on the tedious backend work, all covered by Medicare. The long-term vision is to make 24/7 personalized health assistance affordable for everyone, not just the wealthy or the acutely ill. The company reached early revenue traction within its first year and is growing quickly.
Founded 2025 · roughly 9 people · Industry: Healthcare, AI
The Role
You would own and improve the agentic systems that automate healthcare-navigation tasks on behalf of patients, essentially building the "cursor for nurses": automating outbound voice calls, agentic search, and multi-agent orchestration, using reinforcement learning from real interactions to continuously improve quality.
What you'll be doing
- Automating tasks that healthcare advocates currently do manually, including outbound voice calls to insurance, doctors, pharmacies, and patients
- Building and improving agentic search and multi-agent orchestration systems that coordinate across complex healthcare workflows
- Designing evaluation infrastructure to measure and improve the quality of AI automations so advocates increasingly rely on them
- Implementing reinforcement-learning loops that use real actions to train and improve models over time
- Shipping fast and iterating directly with the team that listens to real conversations daily
Tech stack: Streaming STT/TTS, telephony (Twilio/SIP), multi-agent orchestration, RAG, reinforcement learning
Requirements
- Has shipped voice AI to production, not just prototypes or demos
- 1 to 10 years in AI/ML engineering, including hands-on work on voice systems
- A track record with a production voice stack: real-time streaming speech-to-text and text-to-speech, telephony (for example Twilio or SIP), latency tuning, and endpointing
- Strong agentic-systems experience: context engineering, multi-agent orchestration, tool use, and retrieval-augmented generation
- A clear signal of standout achievement, for example building at a high-growth startup, shipping major products, raising funding, or a comparable distinction
- A computer science undergraduate degree from a top-25 university in the US or Canada
- Comfortable operating in ambiguity, the kind of engineer who builds the playbook rather than following one
- Willing to relocate to San Francisco by Q1 2027
Nice to Haves
- Founder experience (for example YC), time at a fast-scaling later-stage company, or big-tech experience paired with an earlier startup chapter
- Experience building evaluation pipelines for voice systems: quality metrics, regression suites, and production-signal monitoring
Why Join
- Voice is the product, not a feature. Phone conversations are how the work gets done in healthcare, so you would own the company's core capability rather than a side project.
- Join at an early stage on a small team, where your decisions set the technical direction.
- A founding team drawn from leading technology companies, with repeat-startup experience.
- Durable moats in progress: reinforcement learning from real interactions, plus compounding local network effects across the care ecosystem.
