About Us 

ExpoPlatform is a UK-based company founded in 2013, delivering advanced technology for online, hybrid, and in-person events across 30+ countries. Our platform provides end-to-end solutions for event organizers, including registration, attendee management, event websites, and networking tools.

 

Your Role

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. We need someone who is both technically strong and an effective communicator - capable of working independently and proactively.

 

Key Responsibilities

  • Design, develop and support backend modules for our platform serving exhibitions and conferences.
  • Build, document, and maintain robust internal and external RESTful APIs.
  • 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 SOLIDDRYKISS 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.

 

If this sounds like the right challenge for you, we’ll be happy to connect.
