Senior Developer - musicMagpie

About The Role

musicMagpie is part of the AO family, a company that shares our passion for putting customers first, caring for our people, and making a real difference.

musicMagpie is on a mission to make technology more affordable while helping to protect the planet. By focusing on recycling, refurbishing, and reselling tech and physical media, they offer millions of customers a smart, sustainable, and trusted way to buy, sell, and rent devices. From phones and tablets to games consoles and laptops, everything comes together in one place, making it easier for customers to make better choices for both their wallets and the world.

Since joining AO, we’ve been working closely together, creating exciting opportunities to shape the future of sustainable tech and drive meaningful impact, and together, we’re building something bigger and making a difference that lasts.We’re looking for a Senior .NET Developer, to be a core part of one our cross functional teams. Each of our cross-functional teams owns a series of platforms, from development and infrastructure through to ongoing support, so you’ll be a key part of delivering features, enhancements, and general tech related updates within the team. In addition, our teams maintain their own pipelines and infrastructure using IaC best practices.

You’ll be working in an agile team, supporting and mentoring the team in design, development and making high level technical decisions, whilst also working with Product Owners, developers, and external stakeholders to define and work towards achievable goals.

Here's What You Can Expect To Be Doing

You’ll be getting hands-on with building modern .NET Core applications and helping us move legacy systems over to newer tech (bonus points if you’ve touched Ruby or VB, but it’s definitely not a must). You’ll play a big part in shaping our service‑driven architecture, working with .NET Core, APIs and MySQL, and making sure everything we deliver is clean, secure and easy to maintain. You’ll build and deploy into Azure, keep our cloud infrastructure resilient, and drive technical improvements from idea stage right through to production. Collaboration is a big part of the role too — whether that’s partnering with UI Developers for end‑to‑end solutions, working closely with business stakeholders, or supporting the rest of the team to level up. You’ll be designing and working with RESTful APIs, delivering in a CI/CD environment, and always pushing for high coding standards across the team.
