## Job description

## About Smart Working

At Smart Working, we believe the right job should do more than strengthen your CV — it should challenge you, inspire you, and feel right every day. We connect experienced professionals with long-term, full-time remote roles where engineering excellence truly matters. Our mission is to remove geographic barriers and match top talent with global teams building high-impact, mission-critical products. We partner with companies that value precision, ownership, and long-term growth, empowering our people to thrive both professionally and personally. Join one of the highest-rated workplaces on Glassdoor and experience what it means to work in a truly remote-first environment.

## About the Role

Important: Laravel-only experience is not qualifying — proven Symfony experience is mandatory!!!

We’re hiring a Senior Symfony Engineer to work on mission-critical backend systems where code quality, reliability, and accountability are non-negotiable. This role goes far beyond feature delivery, it’s about engineering craftsmanship, technical ownership, and building systems you can truly stand behind.

You’ll be part of a highly collaborative Agile team, working closely with product, QA, and other engineers across the full lifecycle — from ticket definition and design through testing, review, and production deployment. This role is ideal for someone who values clean architecture, Test-Driven Development, thoughtful technical decisions, and mentoring others while building robust, scalable solutions.

## Responsibilities

- Design, develop, and maintain high-quality backend systems using PHP and Symfony
- Own features end-to-end, from ticket creation and technical design to production release
- Write clean, strongly-typed, maintainable, and testable code that meets strict quality standards
- Apply design patterns thoughtfully and consistently
- Build and maintain comprehensive automated test coverage using PHPUnit and similar tools
- Follow and promote Test-Driven Development (TDD) practices
- Use static analysis, linters, and code quality tools to ensure reliability and consistency
- Participate actively in code reviews, providing and receiving constructive feedback
- Collaborate closely with product, design, and QA teams to deliver robust solutions
- Break down complex initiatives into well-defined, actionable tasks and guide implementation
- Monitor systems and participate in a rotating on-call schedule when required
- Promote secure coding practices and ensure code is free from known vulnerabilities
- Document architecture, decisions, and processes to support team-wide knowledge sharing
- Mentor junior and mid-level engineers and contribute to a strong engineering culture

## Requirements

- 5+ years of professional experience with PHP (7.4 / 8+)
- 3+ years of hands-on experience with the Symfony framework
- Strong understanding and practical use of design patterns
- Solid experience with unit and integration testing (PHPUnit, Behat, or similar)
- Hands-on experience with Test-Driven Development (TDD)
- Familiarity with static analysis tools (PHPStan, Psalm, or similar)
- Strong understanding of CI/CD pipelines, code coverage, and deployment workflows
- Excellent technical communication skills and ability to explain and defend technical decisions
- High ownership mindset and strong sense of accountability

Nice-to-Have

- Experience working with MongoDB
- Familiarity with JavaScript, React, Node.js, and/or TypeScript
- Experience with Docker and/or Kubernetes
- Experience working on high-availability or mission-critical systems
