Senior Back End Engineer

We're working with a global digital organisation helping brands build meaningful, high-impact digital products. Their teams sit at the intersection of creativity, technology, and insight - designing and engineering platforms that scale, perform, and genuinely make a difference.

They're now looking for a Senior Back End Engineer to join a cross-functional delivery team working on modern, content-driven web applications.

As a senior engineer, you'll play a key part in shaping and delivering secure, accessible, and high-performing digital solutions. You'll work closely with designers, product specialists, and clients - contributing not just code, but ideas, leadership, and technical direction.

This is a hands-on role with real influence, ideal for someone who enjoys mentoring others and modernising platforms while still being close to delivery.

• Designing, building, and maintaining web applications using C#, .NET Framework, ASP.NET MVC, and Web API
• Building and integrating CMS-driven solutions (e.g. Umbraco, Sitecore or similar)
• Providing technical leadership within your team, including code reviews and mentoring
• Supporting platform modernisation, including adoption of .NET Core, Azure, and modern front-end frameworks
• Collaborating with Product, UX, Strategy, and DevOps to deliver end-to-end solutions
• Championing best practices around accessibility, performance, security, and maintainability

• 5+ years' experience as a Software / Back End Engineer
• Strong experience with C# / .NET, ASP.NET MVC, and Web APIs
• Solid background working with CMS platforms (Umbraco, Sitecore, or similar)
• Working knowledge of front-end technologies (HTML, CSS/Sass, JavaScript; React experience a plus)
• Exposure to Azure, cloud-hosted infrastructure, and modern DevOps practices
• Confident communicator, comfortable working with both technical and non-technical stakeholders
• A collaborative mindset and passion for mentoring others

You'll be part of a supportive, learning-focused engineering community within a large global organisation. We invest heavily in our people - offering opportunities to grow, experiment, and work on meaningful digital products at scale.

Benefits include:

• Competitive salary and benefits package
• Generous paid time off
• Hybrid working and flexible culture
• Access to global learning, development, and career opportunities
• Employee wellbeing and mental health initiatives
• Regular team and community events

If you're an engineer who enjoys combining strong back-end expertise with collaboration and impact, we'd love to hear from you.
