* Architecting and optimising scalable backend systems in Ruby on Rails
* Designing and maintaining clean, efficient APIs and integrations
* Improving performance and database efficiency at scale
* Contributing to long-term technical decisions and platform direction
* Collaborating closely with product, DevOps, and other engineers
What We’re Looking For:
* 6+ years of Ruby on Rails experience in production
* Strong grasp of system architecture, performance, and scalability
* Experienced in designing & maintaining APIs
* Comfortable with CI/CD, Docker, and cloud services (AWS preferred)
* Comfortable owning features end-to-end and contributing to direction
Why Join?
You’ll work on meaningful engineering challenges in a modern Ruby environment - with the scale and complexity to keep things interesting, and the autonomy to help shape how they’re solved.
