Senior .NET Developer Global Tech Company | Agile Delivery Teams | Hands-On | UK-Based Miles of customers, one proprietary platform, infinite possibilities. This global technology business has completed a massive migration to its own platform and is now focused on scale, innovation, and speed. Products are being built at pace, technology is unlocking new capabilities, and the experiences delivered to customers worldwide are next‑level. At the heart of it all is the tech team. They are looking for a Senior .NET Developer to join an agile delivery squad and help shape the future of their platform. What You’ll Do

Build and maintain integrations between web front‑ends, back‑end services, and third‑party systems. Apply software development best practices and design patterns alongside fellow developers and QA engineers. Deliver new features while writing clean, maintainable, high‑quality code. Take ownership of developments from initial implementation through to production support. Collaborate with platform engineering teams to maintain a robust CI/CD pipeline. Ensure all code is testable, covering unit, integration, UI, and performance tests.

Who You Are

Solid commercial experience with .NET and C#. Hands‑on experience with Akka.NET for building distributed, scalable, fault‑tolerant systems. Familiar with N‑Tier architecture and service‑oriented design (SOA). Strong understanding of OOP principles and design patterns. Experienced with Web Services, WebAPI, and WCF. Comfortable with SQL and NoSQL databases. Skilled in performance tuning and optimisation. Confident with Git and source control best practices. Experienced in Agile or Kanban environments. Excellent collaborator and communicator, with a problem‑solving mindset. Flexible for occasional releases or out‑of‑hours support when needed.

Why This Role Stands Out You’ll be joining a team where your work actually matters, helping millions of users around the world interact with cutting‑edge technology every day. You won’t just be maintaining code—you’ll be shaping the platform itself, contributing to a product that is scaling rapidly and innovating constantly.
