Descripción de la vacante

Sourceability is seeking a Senior PHP Application Engineer to maintain, stabilise, and modernise PHP-based applications and integrations within a hybrid, local-office setup. You will work with cross-functional teams to reduce production risk and improve legacy code.

The role emphasizes safe changes, quality, and long‑term engineering ownership. The ideal candidate has strong PHP/Symfony expertise, production experience with RabbitMQ and PostgreSQL, and a passion for robust testing and API

Formación

• 5+ years of professional PHP experience, 3+ years with Symfony
• Modern PHP 8.x with strict typing discipline
• Deep Symfony knowledge (6.x LTS): Dependency Injection, Security, Workflow, and Messenger
• Hands-on production experience with RabbitMQ / AMQP and message-driven architectures
• Strong Doctrine ORM + PostgreSQL skills: query optimisation, batch processing of large datasets, migrations, custom DBAL types
• Strong REST API design - API Platform, FOSRest/JMS, or equivalent, with OpenAPI documentation
• Frontend development with Vue (2 or 3) and Twig; TypeScript proficiency
• Authentication and security: JWT, SAML/SSO
• Third-party API integration with resilience patterns (retries, rate limiting)
• ETL-style data pipelines: streaming processing of large CSV/XML/JSON files
• Strong testing culture: PHPUnit and Behat, comfort with strict PHPStan rules and CI quality gates
• Docker-first development workflow

Responsabilidades

• Maintain, stabilise, and improve existing PHP applications, backend services, and integrations that support Sourceability business operations.
• Diagnose and resolve production defects, application issues, performance problems, data inconsistencies, and integration failures.
• Develop new features and enhancements when needed, while keeping changes safe, maintainable, and aligned with business priorities.
• Read, understand, and improve legacy PHP code without creating unnecessary rewrites or production disruption.
• Refactor problematic areas of the codebase where practical to improve maintainability, reliability, security, and testability.
• Build and maintain integrations between PHP applications, internal systems, third‑party platforms, APIs, ERP systems, and data stores.
• Partner with Product / Delivery Managers to clarify requirements, acceptance criteria, defects, enhancement requests, and business impact.
• Partner with Product Group Team Leads / Architects to align implementation decisions with technical direction, modernisation plans, and engineering standards.
• Work with QA to improve test coverage, regression validation, defect reproduction, and release readiness for PHP applications.
• Work with DevOps, DBA, Infrastructure, and Security teams to troubleshoot deployment issues, environment problems, database performance concerns, and operational risks.
• Participate in code reviews and help raise code quality, documentation discipline, and maintainability across PHP systems.
• Document existing behaviour, integrations, known risks, support procedures, and technical decisions where documentation is missing or outdated.
• Support L3 technical escalation for PHP applications and contribute to root cause analysis after production incidents.
• Identify technical debt, fragile integrations, single points of failure, and modernisation opportunities, then propose practical remediation steps.
• Mentor less experienced engineers when needed and share knowledge about application behaviour, codebase structure, and safe change practices
