Were supporting a leading UK-based client on a major digital transformation journey and theyre looking for a Senior Software Engineer to join one of their most forward-thinking teams.

This role offers the chance to be part of something genuinely transformative: moving from legacy systems to a modern, cloud-native platform built with .NET 8, AWS, Docker, GraphQL and Terraform. The systems you\’ll help build are critical to the daily operations of a large-scale, high-throughput business environment used across the UK and Europe.

Why This Role Stands Out

• You\’ll be part of a genuinely greenfield transformation not maintaining, but modernising.
• Work on scalable, event-driven architecture using the latest in cloud-native engineering.
• Join a high-trust, agile team that values quality, autonomy and continuous improvement.
• Collaborate across engineering, product and DevOps to shape solutions end to end.

What Youll Be Doing

• Designing and building robust, scalable services in .NET 8
• Helping drive the shift from monolithic systems to distributed, microservices-based architecture
• Writing clean, maintainable and well-tested code
• Actively contributing to code reviews, knowledge sharing and mentoring
• Working with a modern engineering toolset including AWS, Docker, GraphQL, DynamoDB and Terraform

The Tech You\’ll Use

• Languages & Frameworks: .NET 8, C#, JavaScript/React
• Cloud & Infrastructure: AWS (Lambda, ECS, DynamoDB, Aurora), Docker, Terraform
• Eventing & APIs: Kafka, GraphQL, REST
• CI/CD: GitHub Actions
• Data: PostgreSQL, DynamoDB, DocumentDB

What We\’re Looking For

• Solid experience building modern, cloud-based systems using .NET and AWS
• Strong understanding of software design principles, clean code, and TDD
• Exposure to infrastructure-as-code and cloud automation (ideally Terraform)
• A collaborative mindset and the ability to work across technical and non-technical teams
• A passion for engineering excellence and delivering high-impact software

Looking for a step up into a truly modern engineering environment? This is a brilliant opportunity to work at the heart of a major platform transformation, using the latest tech in a setting that values autonomy, quality and growth.
