About the role

Key responsibilities & impact

Build and maintain subscription, renewal, and credit logic in a TypeScript service
Own webhook reliability and payment-event correctness end to end

Occasional light React work where your APIs meet the checkout screens

Postgres fluency
Comfort with event-driven systems and async processing

Strong written and spoken English
Availability during US business hours
Go
