About the Role
We're seeking full stack engineers to expand our platform's API and service capabilities. You'll design, implement, and support high-performance, maintainable code that integrates cleanly across multiple modules and external systems. This role is hands-on: building production-grade code, reviewing pull requests, and helping shape our architectural standards. You'll work closely with DevOps, QA, and UI teams to ensure seamless delivery. This is an ONSITE role in Phoenix with genuine flexibility. Core collaboration hours are 10 AM–3 PM — manage your schedule around that. We don't track hours or micromanage — we hire professionals and treat them accordingly. You'll work with experienced engineers who value clean design, accountability, and getting things done right.
