Senior Software Engineer (C#, .NET, SQL, Azure)
Project - the aim you'll have
We are looking for an experienced Senior Software Engineer to join an engineering-led team building scalable, cloud-native backend systems that power data-driven products at scale. This role focuses on designing, developing, and operating production-grade services in Azure, emphasizing event-driven architectures, automation, and long-term maintainability. Engineering decisions are driven by technical quality and automation rather than process or hierarchy. As a senior engineer, you will shape system architecture, set engineering standards, and ensure solutions are robust, scalable, and fit for purpose. This is a hands-on role with real ownership and influence over technical decisions.
Position - how you'll contribute
- Design, develop, and maintain scalable backend services using cloud-native and serverless patterns
- Build and operate message-based systems to handle high-throughput data flows (Event Hubs or Service Bus)
- Develop containerised services and Azure Functions
- Implement and manage infrastructure as code using Terraform
- Contribute to architectural discussions and guide technical direction through experience and best practices
- Collaborate closely with other engineers, influencing technical decisions and raising engineering standards
Expectations - the experience you need
- Knowledge of C# 14.0
- Azure cloud services: CosmosDB, Function Apps, Container Instances, Container Registries, Blob Storage, Event Hubs, Key Vault
- SQL within application contexts
- GitHub, Azure DevOps, and Datadog
- CI/CD pipeline development using YAML and Terraform
- Experience with AI development tools (e.g., GitHub Copilot, Claude Code)
Additional skills - the edge you have
- Ownership mindset: take systems from design through production
- Strong architectural thinking: scalability, reliability, maintainability
- Comfortable making technical decisions and explaining trade-offs
- Continuous improvement mindset; willing to challenge existing solutions
- Collaborative and pragmatic senior engineering approach
- Nice to have: experience with AI developer tools (e.g., GitHub Copilot, Claude Code)
