Referment is working with a global financial services business seeking a Software .NET Developer to build enterprise applications supporting client onboarding and shared workflows across the organisation.

You will join an engineering team responsible for low-latency, business-critical systems and contribute across the full application stack. The remit covers the complete development lifecycle, from architecture and proof of concept through implementation, testing and release. It offers a strong fit for an experienced .NET engineer who enjoys combining backend depth with modern web development and contributing technical direction to a wider team.

The Role

• Design and develop scalable enterprise applications across frontend, backend and data layers.
• Contribute throughout an Agile development lifecycle, from concept and architecture through testing and production release.
• Write efficient, testable code and ensure designs meet agreed technical specifications.
• Build proofs of concept to evaluate new technologies and architectural ideas.
• Review pull requests and help strengthen engineering standards and delivery practices.
• Mentor other engineers and provide practical technical guidance.
• Investigate alternative approaches and present recommendations for architectural review.
  
  

What We're Looking For

• At least five years' experience building enterprise-grade systems.
• Strong hands-on development experience with C#, .NET Core and .NET 8 or later.
• Experience creating large, scalable web applications using React ideally, or Angular, with TypeScript.
• Practical knowledge of event-driven microservices and distributed systems.
• Experience with Docker, Kubernetes and a cloud platform such as Azure or AWS.
• Exposure to Apache Kafka or a comparable distributed messaging or streaming platform.
• Sound testing practice, including TDD or BDD and relevant testing frameworks.
• Strong knowledge of relational SQL and NoSQL databases.
  
  

A computer science, engineering or related degree is required. Financial-markets knowledge is useful, although a strong desire to learn the domain can also work.

This could suit a senior full-stack or backend-focused .NET engineer who wants to work on complex onboarding workflows while remaining hands-on across architecture, delivery and mentoring.
