We're looking for a backend engineer who thrives in fast-moving environments and enjoys building robust systems end-to-end. You'll work across data pipelines, APIs and infrastructure, ensuring our platform runs efficiently and scales cleanly as we grow.

Your role

  • Develop and maintain backend features and APIs for our core platform
  • Improve database performance, reliability and real-time data processing
  • Debug, profile and optimise code to keep latency low and systems stable
  • Collaborate with AI, frontend and product teams to integrate new capabilities
  • Contribute to architectural decisions and shape the evolution of our backend stack

You are

  • 3–5 years' experience building production-grade backends (Python preferred; Go, C++, or Java also valuable)
  • Solid in SQL and data modelling (PostgreSQL or similar)
  • Experienced with REST APIs and cloud environments (AWS preferred)
  • Comfortable working independently and taking ownership of a problem
  • Startup mindset — quick to ship, focused on quality, allergic to bureaucracy

Nice to have

  • Linux debugging and performance tuning
  • Familiarity with orchestration (Kubernetes, Terraform, Ansible)
  • Experience with data pipelines or analytical databases
  • Interest in edge/cloud hybrid architectures

Why this role matters

You'll help shape how data moves through our system — building fast, reliable infrastructure that powers every customer interaction.
