Senior Python Backend Engineer (AI-First, High-Scale Image Processing)

Referment is partnering with an innovative, AI-first technology company transforming how visual content is processed at scale. Their platform powers millions of image enhancements globally for major enterprise clients, combining cutting-edge infrastructure with real-world impact.

This is an opportunity to join a small, highly skilled team where your work directly shapes a product used around the world.

Why This Role Stands Out

• Work on genuinely high-scale systems processing millions of images
• Tackle complex performance challenges across GPU and cloud infrastructure
• Be part of a modern engineering environment that embraces AI-assisted development
• Join a team where your contributions are visible and impactful from day one
  
  

What You Will Be Doing

• Designing and building robust Python APIs handling high-volume workloads
• Scaling and optimising backend systems across AWS infrastructure

The Details

• Fully remote within the EU, with a preference for UK-based candidates
• Permanent role
• Collaborative, product-driven team with an AI-first approach to development
  
  

If you enjoy solving challenging scaling problems, optimising real-world systems, and working with modern tooling, this is a fantastic opportunity to take ownership and make a meaningful impact.
