Second-hand fashion is projected to reach $350bn by 2027.

The hard part isn’t demand - it’s infrastructure.

I’m hiring a Backend Product Engineer for a high-growth consumer business building the infrastructure behind the circular economy for second-hand fashion.

This is not a ticket factory.

What you’ll be working on:

• Rebuilding a core marketplace from first principles
• Turning messy, offline supply chains into scalable systems
• Backend systems tightly coupled to product and commercial outcomes
• Real consumer scale, growth, and experimentation
• Owning decisions end to end — design → build → ship

Tech-wise:

• AWS, TypeScript & Node
• Open to Python, Go, Java, etc.
• Strong fundamentals > language loyalty

This will suit you if you like:

• Ambiguity and ownership
• Product-led engineering
• Systems that directly affect users, supply, and revenue
