Are You a Talented Engineer?
Are you a talented engineer who loves building clean, functional code and solving technical challenges in PHP?
Join our team as a Mid-Level Backend Engineer, where you will help evolve our global platform serving more than 20 million users. We value strong engineering fundamentals, a growth mindset, and the ability to deliver reliable features in a fast-paced environment. While we use Laravel, we highly value the core engineering skills of Symfony developers who are eager to adapt their expertise to our ecosystem.

- Contribute to our modular architecture, helping us build resilient, service-oriented systems.
- Write clean, maintainable code by applying SOLID principles, OOP best practices, and design patterns.
- Master the art of debugging, identifying and resolving issues across our stack with precision.
- Integrate asynchronous processes using queues and basic event-driven patterns to improve system efficiency.
- Collaborate closely with Senior Engineers and Product teams to turn requirements into high-quality technical solutions.
Does This Sound Like You
- 3-5 years of professional backend development experience with a solid command of PHP.
- Proven experience building applications in Laravel or a strong background in Symfony with a desire to transition.
- Strong understanding of OOP, interfaces, and code modularity; you know why "clean code" matters.
- Solid knowledge of SQL, including database indexing, migrations, and basic query optimization.
- AI Proficiency: Ability to effectively use AI tools during technical tasks; we value engineers who know how to prompt, validate, and iterate with AI to build better software faster.
- Familiarity with modern infrastructure, including Docker and basic CI/CD pipeline troubleshooting.
- Experience with testing, specifically writing unit and feature tests to ensure code reliability.
- Fluent English with the ability to communicate technical progress and seek support effectively within a remote team.
