We are looking for a highly experienced Senior PHP Developer to join our team and take ownership of key backend components in a dynamic, product-driven environment. You will play a crucial role in shaping the architecture, scaling the platform, and mentoring less experienced developers.

- Participate in system architecture design, refactoring, and performance optimization.
- Collaborate with Staff Software Engineers to ensure technical consistency and scalability across the platform.
- Work closely with Engineering Managers to align technical delivery with product and business goals.
- Engage in cross-team discussions to improve engineering standards and share best practices.
- Translate business requirements into scalable, reliable technical solutions.
- Write clean, maintainable, and testable code in adherence to best practices.
- Act as a technical leader in the team, mentoring mid-level and junior developers.
- Ensure security, performance, and reliability of backend components.
Qualifications
- 7+ years of hands-on experience in backend development with PHP.
- Proven experience with one of the PHP frameworks (Laravel, Symfony, Phalcon).
- Deep understanding of OOP, design patterns, and architectural principles.
- Experience with PostgreSQL (or other RDBMS), including performance tuning and optimization.
- Strong Git workflow knowledge and experience working in a collaborative Git environment.
- Solid grasp of SOLID, DRY, KISS principles and Domain-Driven Design.
- Experience working in agile, cross-functional product teams.
- Strong communication skills and ability to explain technical topics clearly across both technical and non-technical audiences.
- Self-motivated with ability to independently drive tasks to completion.
- Proficient in writing clear technical documentation.
- Experience with CI/CD pipelines (e.g., GitLab CI, Jenkins, GitHub Actions).
- Ability to model and communicate architecture using C4 diagrams or similar.
- Exceptional experience with PHPUnit or other test frameworks.
Nice to Have
- Experience with AWS (e.g., EC2, S3, RDS, CloudWatch, Lambda).
- Familiarity with event-driven architecture, message queues (e.g., RabbitMQ, SQS).
- Skills in frontend technologies: basic JavaScript, HTML5/CSS, or exposure to Vue/React.
What We Offer
- Opportunity to build quality infrastructure for a platform used globally in the live events industry.
- Fast-paced environment with a growing international team.
- Competitive salary and performance-based incentives.
- Flexible work hours and remote work options.
- Professional development and learning budget.
