Backend Developer (mid-level), PHP / Node.js

• Work across our two main stacks: a PHP API and Node.js microservices.

• Design and evolve database structures, and care about how queries behave at scale.

• Debug real production issues and help make the system more reliable over time.

• Around 2-4 years building backend applications you can talk about in depth.

• Solid grounding in at least one object-oriented language. PHP or Node.js is a plus, but strong fundamentals plus a real willingness to learn our stack matter more.
