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.

- 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:
- Designing scalable systems with high concurrency
- Building custom libraries/reusable components
- API architecture and third-party integrations
- Performance optimization & database tuning (MySQL)
- Async processing, queues, and caching (Redis)
- Secure systems (payments, financial data preferred)
Ideal Candidate Profile:
- Has contributed to meaningful open-source projects OR

Interview Process:

Logistics:

- Travel 1–2x/year max
Screening Questions:
