  • Strong with REST APIs, JSON, HTTP, and webhooks — you read API docs and integrate without hand-holding

  • JavaScript/TypeScript proficiency (Node.js); Python is a plus

  • Comfortable with formal/boolean logic and state management — the same thinking that makes an AI agent behave correctly

  • Located in Colombia and available during US Central business hours

  • Build and maintain the platform behind our AI voice agents: Supabase/PostgreSQL backend, REST APIs, and webhooks

  • Direct work with the founder; your code and configurations ship to paying customers within days

  • Hands-on experience across production voice AI, Supabase, workflow automation, and enterprise low-code
