Job Description

Senior Full-Stack Engineer

EXIT83 AI

• You'll be on a high-impact team building a vertical SaaS platform that thousands of service businesses rely on every day. • This is a hands-on senior role with real influence over product direction, architecture, and the engineering culture as the team scales. • The platform is mid-migration from a mature PHP codebase to a modern Node.js and React stack, with a React Native mobile app already in production. • You'll work across both sides of that transition: shipping features in the legacy codebase while helping architect and build the system that replaces it. • Own features end-to-end, from scoping with product to deployment and monitoring • Partner with product and customer-facing teams to translate real user problems into technical solutions • Contribute to the best practices in the modern stack: testing strategy, code review standards, CI/CD, developer experience • Contribute to architecture and technical direction conversations as a peer, not a reviewer

Job Requirements

  • 5+ years of professional software engineering experience, with a strong full-stack track record
  • Production experience with PHP
  • Solid experience with Node.js and modern JavaScript or TypeScript
  • Working knowledge of React for web
  • Experience with relational databases (MySQL or PostgreSQL)
  • Track record of owning features end-to-end on a small team, including scoping, building, shipping, and supporting in production
  • Result-oriented and proactive, comfortable working with autonomy
  • Nice to Have: Experience leading or contributing to a large-scale codebase migration (PHP to Node/React or similar)
  • REST API design and third-party integrations (payments, mapping, routing, scheduling)
  • Cloud infrastructure experience (AWS, GCP, or similar)
  • Comfort with CI/CD pipelines, automated testing strategy, and DevOps practices

Benefits

  • Remote work options
