About the Company

The company is building AI-powered clinical workflows that eliminate administrative burden for home health clinicians.

Already deployed across thousands of clinicians serving tens of thousands of patients daily, the platform automates documentation, streamlines workflows, and allows healthcare providers to spend more time delivering patient care.

Founded by experienced AI researchers and operators with backgrounds in large-scale AI systems, the company has rapidly gained traction within healthcare and recently completed a Series A financing round to support aggressive growth.

As the first dedicated AI hire, this Senior AI Engineer will own the intelligence layer of the platform, building the systems responsible for model accuracy, evaluation, inference, monitoring, and production AI workflows.

This is a rare opportunity to join an early-stage healthcare AI company with real-world deployment, proprietary clinical datasets, and significant ownership over the future of the AI organization.

What You'll Do

• Train and fine-tune open-source foundation models using proprietary healthcare datasets
• Build evaluation frameworks, benchmarks, and monitoring systems that continuously improve model quality
• Design metrics, feedback loops, and accuracy measurement systems tied to real-world clinical outcomes
• Build scalable and cost-efficient inference infrastructure for production AI systems
• Develop agentic AI workflows that clinicians rely on daily
• Improve model accuracy, latency, reliability, and observability across production environments
• Partner closely with founders and leadership on AI strategy and technical direction
• Prototype new AI capabilities and rapidly transition them into production systems
• Stay current on frontier AI research and incorporate new techniques into production workflows
• Help establish the long-term AI roadmap and eventually build and mentor the AI team
