Substrate, a YC S24 seed‑funded startup, is hiring a Technical Success Manager to shepherd clients through its AI‑driven revenue‑cycle‑management platform. The role centers on turning complex healthcare claim workflows into smooth, data‑driven experiences for physician groups, EMR vendors and BPOs. Candidates must blend technical troubleshooting with client advocacy and delivering value at scale for customers.

Substrate’s solution already processes over 500k claims monthly, aiming to capture a slice of the $14 billion outpatient RCM market. The new hire will own end‑to‑end client relationships, diagnose production anomalies, and prototype tools that expose agent behavior. Deep familiarity with LLM fine‑tuning and SQL is essential for this hands‑on role and technical ownership in healthcare.

Candidates will act as the primary liaison from pilot to expansion, proving solutions before engineering builds them. They must dissect codebases, query production databases, and translate vague client pain points into high‑fidelity use cases. Substrate’s culture rewards extreme ownership; blockers are bypassed by creative detours, and uncertainty prompts independent investigation for long‑term success and client.

Substrate offers a meaningful salary plus equity, reflecting its ambition to replace manual RCM staff with browser‑based AI agents. The Technical Success Manager will shape how the company scales, ensuring clients see faster reimbursements and lower costs. With deep healthcare, AI, and full‑stack expertise, Substrate aims to disrupt a market that has long resisted automation.
