THE ROLE: You'd own agent orchestration, monitoring, and ML operations as founding technical leader. We have agents built by external agency launching in 2-4 weeks.

THE TRIAL: Week 1: Evaluate third-party agent code, build monitoring infrastructure, or pivot to corrective strategy if code needs work. Testing judgment + execution + communication.
LOOKING FOR: - Production experience with LLM agents or ML systems - Can leverage AI tools (Claude/Cursor) to accelerate safely - Comfortable with ambiguity, short runway, high ownership - Wants equity upside, sees potential in healthcare transformation - CTO-level strategic thinking
NOT A FIT IF: - Need structured W2 role with benefits - Want low-risk established company - Optimizing for maximum cash vs. equity potential - Need multiple approval layers for decisions
TO APPLY: Email mark@evercred.com with: 1. Your approach to the trial problem (3-5 sentences) 2. Why 20% equity interests you vs. full cash 3. How you'd use AI tools to accelerate the week
We respond within 24 hours. Strong candidates start immediately.
