Role Overview

Our client, operating in the financial services space, is scaling out a modern, event-driven platform and needs a Back-End Developer who can operate across the full lifecycle.

This is not a narrow coding role. You will take ownership of services from design through to deployment and production support, working in a DevOps-led environment with high standards around reliability and security.

What You’ll Be Doing

• Designing, building, testing, and deploying backend services and APIs end-to-end
• Owning build, release, and operational responsibilities for your services
• Developing cloud-native applications using C# / .NET within Azure
• Building event-driven architectures using Azure-native services
• Deploying and managing containerised workloads via Azure Kubernetes Service (AKS)
• Defining infrastructure using Terraform in line with engineering standards
• Implementing messaging patterns with Azure Service Bus and/or Kafka
• Designing data solutions across Azure SQL, Cosmos DB, and storage services
• Exposing APIs using Azure API Manager (APIM)
• Contributing to CI/CD pipelines and maintaining high standards across security, performance, and reliability
• Working closely with architects and platform teams in an agile delivery setup

What They’re Looking For

• Strong backend engineering experience using C# / .NET
• Proven experience working within Microsoft Azure environments
• Background in financial services (banking, insurance, fintech, or similar)
• Solid understanding of SQL and data modelling
• Experience with distributed systems or microservices architectures
• Hands-on exposure to:
• Azure Kubernetes Service (AKS)
• Event-driven architectures
• Azure Service Bus or Kafka
• Azure API Manager (APIM)
• Monitoring tools such as Log Analytics / Application Insights
• Experience with Terraform for infrastructure as code
• Familiarity with CI/CD tooling and DevOps practices
• Comfortable working in fast-paced, agile delivery teams
• Strong communication skills, able to engage with both technical and non-technical stakeholders

Why This Role

• Direct exposure to a financial services end client with complex, high-impact systems
• Full ownership across engineering and DevOps, not just delivery
• Modern Azure stack with event-driven architecture and containerisation
• Hybrid working model with meaningful in-person collaboration
• Strong likelihood of extension beyond the initial 6 months

If you have a Microsoft stack background and experience delivering within financial services, this is a high-quality contract with immediate impact.
