PHP/Symfony Developer (Middle / Senior)

Our client US based IT product company is looking for PHP/Symfony Developer (Middle / Senior).

Required:

• Solid hands-on experience with PHP 8 + Symfony 6/7 — 5+ years
• Experience with legacy PHP code: able to work through an undocumented, older codebase and refactor without breaking existing behavior
• Understanding of Symfony architecture: controllers, services, the DI container, event subscribers, voters
• Symfony's Security component: custom UserInterface implementations, JWT authentication (Lexik JWT Bundle or equivalent), custom authorization checks implemented at the service level (not just #[IsGranted])

• Designing and implementing REST APIs: routing, serialization, input validation, structured error handling

   

Databases

• Doctrine ORM — entities, repositories, DQL, migrations
• PostgreSQL — queries, indexes, optimization, transactions
• MongoDB + ODM — working through the ODM on the backend; writing direct queries and aggregation pipelines, MongoDB Compass or shell (the primary store for DLP events)

Nice to Have

• Experience with MCP (Model Context Protocol) or any similar "LLM calls a backend tool" protocol — understanding why that contract can't be changed silently on one side
• WebSockets / SSE — implementing real-time communication on the backend
• Python — reading-level understanding: FastAPI services, async code, Pydantic schemas; no need to write Python
• Redis — understanding of caching, TTLs, session storage
• LLM / AI integrations — understanding of tool-calling, system prompts, and why a fail-closed approach matters when handling someone else's data
• Background in cybersecurity or compliance (DLP, SIEM, SOC) — strong advantage
