ABOUT THE ROLE:

We're looking for a Senior Software Engineer to help build and run the cloud-native back-end systems behind our data products. You'll design and operate production services in Azure, with a focus on event-driven architectures, automation, and keeping systems reliable as they grow. You'll join an engineering-led team of 7 people where decisions are driven by technical quality rather than process or hierarchy, working closely with other engineers and the Team Lead. Success looks like well-architected services running dependably in production, engineering standards the team can build on, and a genuine say in our technical direction.

WHAT YOU'LL BE DOING:

• Design, build, and operate scalable back-end services using cloud-native and serverless patterns
• Build and run high-throughput, message-based systems on Azure Event Hubs
• Develop containerised services, Container Apps and Azure Functions
• Manage infrastructure as code with Terraform
• Work with data primarily through SQL, writing queries and lightweight database-level logic that support application functionality
• Own services in production, from deployment through to monitoring, observability, and operational stability
• Shape system architecture and technical direction, and help raise engineering standards across the team
• Identify and resolve technical debt, performance issues, and reliability risks before they escalate
• Act as a trusted technical partner to the Team Lead, providing continuity and support when needed.

WHAT WE'RE LOOKING FOR:

• Experience building and operating production back-end services in C# / .NET
• Strong SQL skills, with experience across relational or analytical databases
• Hands-on experience with Microsoft Azure and cloud-native architectures and AI or ML technologies in a production context
• Experience designing event-driven or distributed systems
• Comfortable working with infrastructure as code (Terraform or similar) in CI/CD-driven environments
• Strong architectural thinking, with attention to scalability, reliability, and maintainability, and the ability to own work from design through to production
• Comfortable making technical decisions and explaining the trade-offs behind them
• A continuous-improvement mindset, happy to question existing solutions and to mentor others through code reviews and shared problem-solving
• Fluent English (B2 or higher).

If you don't meet every requirement but feel excited about this role, we'd still love to hear from you.

🚀            A progressive, non-hierarchical culture where innovation drives everything we build
