Full Job Description
đź“‹ Description
- • Architect and deliver high-impact PHP 8 solutions that power Planner5D’s 90-million-user ecosystem. You will own the full lifecycle of complex features—from whiteboard sketches to production deployment—ensuring every line of code can scale to Antarctica and back.
- • Translate ambitious product visions into robust, maintainable back-end services. Working shoulder-to-shoulder with designers, front-end engineers, and 3D graphics specialists, you will shape APIs that synchronize floor-plans, textures, and real-time renders across Web, iOS, Android, Windows, and macOS.
- • Champion SOLID, STUPID, and Domain-Driven Design (DDD) inside the squad. You will lead code reviews, enforce architectural guardrails, and mentor juniors so that our monolith evolves into a clean, modular domain-oriented codebase without ever slowing delivery.
- • Build bullet-proof REST and GraphQL endpoints that serve millions of concurrent requests. You will profile, cache, and optimize queries until our MySQL/PostgreSQL clusters purr, then document every endpoint in swagger-like clarity for our global developer community.
- • Write PHPUnit tests that reach 80 %+ coverage without becoming brittle. You will set up CI pipelines that run static analysis, mutation testing, and integration suites on every pull request, giving the team confidence to refactor fearlessly.
- • Integrate with message queues (RabbitMQ/Kafka) and containerized micro-services to offload heavy tasks—think photorealistic render farms and AI-driven furniture suggestions—while keeping the core PHP stack lightning fast.
- • Keep security at the forefront: OWASP top-10 audits, dependency scanning, and GDPR-compliant data handling are part of your daily rhythm. You will partner with our InfoSec guild to turn compliance into a competitive advantage.
- • Stay ahead of the curve. Whether it’s PHP 8.3 JIT improvements, TypeScript adoption, or React server components, you will experiment, spike, and present findings that keep Planner5D on the bleeding edge of home-design tech.
- • Collaborate asynchronously across 15+ time zones. You will communicate progress in crisp English, demo features in fortnightly town-halls, and celebrate wins in both virtual and in-person gatherings in Vilnius, Lisbon, or Tbilisi.
- • Own your calendar. As a B2B contractor you decide when and where you work, yet you commit to sprint goals and OKRs that move the needle for millions of dream-home creators worldwide.
