We are looking for engineers who have experience building or working with custom frameworks, core backend systems, and high-performance PHP applications. If your experience is primarily CMS or standard web development (WordPress, Drupal, basic Laravel apps), this role will not be the right fit.

You must have at least one of the following:

  • Experience building or maintaining a custom framework
  • Contributions to open-source backend libraries/frameworks
  • Experience working on high-load, scalable backend systems

You’ll be working directly with a highly technical CTO who is deeply experienced in PHP and backend system design. We are looking for engineers who think beyond frameworks — those who understand how systems work under the hood and can build them from scratch.

The Role: We’re looking for a top-tier Senior PHP Backend Engineer to help build and scale a custom, high-performance backend infrastructure. This is NOT a standard PHP/Laravel role.

  • Design scalable, high-performance APIs and services
  • Optimize for high concurrency, low latency, and reliability
  • Work closely with the CTO (PHP expert) on system design and architecture
  • Drive best practices in security, testing, and performance

Tech Stack:

  • PHP (custom architecture – not relying on Laravel/Symfony)
  • FrameworkX (async processing)
  • React (frontend)
  • MySQL, Redis, queues

What We’re Looking For (Must-Have):

  • Strong PHP engineering background (7+ years)
  • Proven experience building or working with custom frameworks (ESSENTIAL)
  • Experience building applications/platforms (not just web apps)
  • Ability to work without heavy framework reliance

Strong Technical Experience In:
