In the world of Enterprise SaaS, the Backend is where the battle for stability is won or lost. At DuskByte, we specialize in taking 10-year-old PHP monoliths and transforming them into high-performance, modular engines. As a Senior Backend Engineer, you will use your decade of experience to decouple spaghetti code, modernise database schemas, and build the APIs that power the next generation of our clients platforms.
What You Will Do (The Role)
Monolith Decoupling
Lead the strategic refactoring of massive Symfony or Laravel applications into clean, service-oriented architectures.
API Modernisation
Design and implement robust, versioned RESTful or GraphQL APIs to replace aging, undocumented internal endpoints.
Database Hardening
Audit and optimize complex SQL (PostgreSQL/MySQL) environments, fixing N+1 queries, poor indexing, and data integrity issues.
The Strangler Strategy
Build the middleware and wrappers necessary to transition legacy business logic to modern services without breaking front-end functionality.
Performance Engineering
Implement advanced caching strategies (Redis/Memcached) and asynchronous processing (RabbitMQ/SQS) to stabilize high-traffic B2B platforms.
You are a master of the PHP ecosystem and its infrastructure
The Frameworks
Deep, expert-level knowledge of Symfony (5.x/6.x) and Laravel (9.x/10.x/11.x).
The Language
Mastery of up-to-date PHP 8.x features (Attributes, JIT, Fiber) and how to upgrade legacy 5.x/7.x codebases safely.
Expert SQL optimization and experience with ORMs (Eloquent/Doctrine) vs. raw, high-performance queries.
Strong grasp of Design Patterns (Solid, Repository, Factory) and Domain-Driven Design (DDD).
Comfort with Docker, Linux environments, and CI/CD pipelines.
