Senior Software Engineer C#, Azure, Event-Driven Systems

Senior Software Engineer (C#, Azure, Event-Driven Systems)£75,000-£8,000 + Bonus + Shares St Albans (Hybrid)

A long-established, high-growth technology business is beginning a major architectural rebuild following several acquisitions. They are unifying multiple systems into a single source of truth and preparing to scale their platform significantly over the next five years.

They are hiring a Senior Software Engineer to play a key role in designing, building, and delivering the next-generation event-driven platform.

You'll help break down a large monolith into a distributed, event-driven system processing several million events per day, scaling further as new markets open. This role is hands-on: building services, solving technical challenges, and contributing to the engineering standards that will define the new platform.

Key Responsibilities Build scalable, resilient, event-driven services using C# and Azure. Work on distributed systems that support high-throughput, high-availability environments. Deliver features end-to-end with a focus on performance, reliability, and maintainability. Collaborate with Engineering Leads, Architects, and Product to refine designs and deliver roadmap goals. Contribute to the multi-year shift towards microservices and cloud-native architectures. Participate in design reviews, pair programming, and code quality initiatives. Support improvements to CI/CD, testing practices, and production reliability.

What You Bring Solid experience building distributed systems or event-driven architectures. Strong C# and Azure engineering background. Understanding of microservices, messaging, and modern architectural patterns. Track record of delivering secure, stable software into production. Comfort working in a large-scale transformation environment. Willingness to learn, collaborate, and influence engineering best practice.

Why JoinThis is an opportunity to help rebuild a major platform from the ground up, working with modern cloud tooling and a roadmap that values engineering excellence. You'll make a visible, long-term impact while developing your technical depth alongside experienced engineering leaders.
