Node.js Backend Developer

Come Back Agency supports US software and technology companies by running their hiring process. We work with delivery and leadership teams to define roles, screen candidates, and manage interviews. Successful candidates are hired directly by the company and become part of its team.

This position is with a US-based software company providing custom development and AI implementation for North American clients. The team builds and maintains production software, including AI-enabled systems, and works in long-term client engagements. Team members operate as part of an internal, distributed team and collaborate directly with client stakeholders.

Design and build REST APIs working with PostgreSQL and Prisma
Implement business logic and integrations with third-party services
Build authentication and authorization flows
Improve performance and stability of production systems
Investigate and fix production issues
Take part in code reviews and technical discussions
