PHP/Symfony Developer (Middle / Senior)
First seen by Alion on Nov 10, 2026.
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
