.Net Developer

Are you a .NET developer with a passion for building clean, scalable applications-and want your work to make a real-world impact I'm hiring for a .NET Software Developer to join a sustainability-focused eCommerce business that's reinventing how we think about books, logistics, and the circular economy.

They process over 500,000 pre-loved books every week, ensuring they're re-used instead of going to landfill-while funding literacy initiatives around the world. You'll play a core role in evolving the systems that make this possible: from eCommerce platforms to warehouse fulfilment software.

As a mid-level developer, you'll work across the full development lifecycle-designing, building, testing, and optimising core systems across their .NET-based stack. You'll contribute to backend infrastructure and occasionally dip into frontend tools, working closely with product, analysts, and devs in a collaborative and low-ego environment.
