Senior Backend Engineer (PHP --> TypeScript)

Job Details










Role Overview:


Own the sunset of a large PHP codebase and help build its TypeScript replacement. We're a profitable, fast-growing SaaS company that is transforming how people interact with the web.


What you'll do:




  • Draw the boundaries: Identify seams, design contracts (APIs/queues/adapters), and strangler-fig subsystems out of PHP.




  • Keep it stable: Maintain a complex and beloved PHP 7.4 system in production.




  • Build the replacement: Pair with our TypeScript team to implement new services, migrate data/flows, and retire PHP components.




Our Tech Stack:




  • Core: TypeScript, MySQL, Redis, AWS, Kubernetes, Temporal, GitHub, Grafana




  • AI helpers: Cursor, Claude Code, Codex




You'll thrive if you:




  • Have 5+ years of backend experience with 3+ years in PHP on large systems.




  • Have shipped a migration or can show equivalent systems thinking.




  • Are an exceptional debugger who can isolate root causes in unfamiliar code, use logs/profilers well, and land fixes with minimal guidance.




  • Want to spend increasing time in TypeScript as PHP disappears.




You might not love it if you:




  • Want only greenfield work.




  • Need perfect specs before you start.




  • Prefer polishing code over retiring code.




How we work:




  • Ship often, own outcomes, debate ideas not egos, delete code that no longer serves us.




  • Mentorship, pairing, and a clear path to TypeScript ownership post-cutover.




Location & Lifestyle:




  • Hybrid - located in a downtown core of a major US city, 3 days/week.




  • Walkable to local amenities.




Compensation & Benefits:




  • Competitive base, bonequity based on level.




  • Top-spec laptop, private Health/Dental/Vision + wellness stipend, 401(k) match.




  • 20 days PTO + US holidays; flexible hours; weekly team lunches; monthly outings
