Senior Software Engineer (.NET) – Greenfield Project
Location: Leeds (Hybrid – up to 2 days per week in the office)
Salary: Up to £70,000 + Bonus + Excellent Benefits
Type: Full-time, Permanent
We’re supporting a leading UK-based client on a major digital transformation journey — and they’re 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 You’ll 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.
