Description

About the team: At Vintage Cash Cow, technology is how we scale impact. Every customer journey, from sending in pre-loved items to getting paid, is powered by the systems we design, the products we build, and the data we unlock.

Our Technology & Data team is at the heart of this transformation driving greenfield product development, experimenting with fresh ideas, and bringing innovative solutions to life. We’re building modern, scalable, and customer-focused platforms that set the standard for the re-commerce industry.

This is a team where curiosity meets craft: blending creativity, technical excellence, and a product mindset to deliver experiences that feel simple, rewarding, and future-proof.

About the role: We’re looking for a Senior Full Stack .NET Developer to shape the next generation of Vintage Cash Cow’s platforms. This isn’t a “keep the lights on” role, it’s a chance to build fresh, modern solutions from the ground up. You’ll be designing and developing APIs and Blazor applications on .NET 9.0, driving forward greenfield projects, and helping us rethink what’s possible for our customers and teams.

With a product mindset at the core, you’ll collaborate closely with engineers, product managers, and designers to create software that doesn’t just work, but delights. If you’re the kind of developer who’s curious, coachable, and excited to leave your mark on something new—you’ll thrive here.

This role can be based in either the UK or the Netherlands.
