• API Contract Design: Establishing integration boundaries with the rest of the backend team.

Requirements:

• 5+ years of Java / Spring Boot experience in production.
• Proficiency in setting conventions for Maven, Flyway, and Spring Security.
• Deep experience with Stripe or equivalent payment gateways.
• Strong background in webhook management and failure-handling logic.
• Experience with PostgreSQL and AWS at the application level (managing secrets, endpoints, and config changes).
• We need someone who can step in as the strongest Java integration engineer on the team from day one.
