High-growth Product Engineering Team
Build and evolve core Back End services powering a large-scale property technology platform
We're supporting a well-established, product-led technology business that's continuing to modernise and scale the Back End services behind its core platform. This is a critical engineering role within a mature but evolving environment, focused on building robust, cloud-native services that support real-world, high-volume usage.
This role suits an experienced contractor who enjoys owning Back End systems end-to-end, working in production environments, and influencing how services are designed, built and shipped, not just delivering tickets.
You'll operate as a Staff-level, hands-on engineer, embedded within a product squad and working closely with senior engineering leadership to set technical standards and deliver meaningful outcomes.
The role
This is a product-focused Back End engineering position, not a support or maintenance role:
- Design, build and ship cloud-native Back End services using C# and .NET (Core 8/9)
- Own features end-to-end, from early problem discussions through to production delivery
- Build and evolve event-driven systems using AWS serverless technologies
- Design and optimise data models across relational and NoSQL databases
- Create clean, well-documented APIs with a strong focus on developer experience
- Partner closely with BAs, Principal Engineers and delivery teams to shape solutions
- Influence architectural decisions and raise engineering standards across the squad
- Mentor engineers through code reviews, pairing and technical guidance
- You'll be joining a collaborative engineering group with strong technical leadership, clear ownership, and the space to make real impact.
- Senior/Staff-level Backend Engineer with strong ownership mindset
- Deep hands-on experience with C# and modern .NET in production environments
- Strong background in AWS serverless architecture (Lambda-first)
- Experience building distributed, event-driven systems
- Comfortable designing data models across SQL and NoSQL
- Able to work from high-level business problems to pragmatic technical solutions
- Confident communicator who can explain trade-offs to both technical and non-technical stakeholders
- Pragmatic and outcome-focused, values shipping, quality and maintainability over perfection
- AI-assisted/agentic development workflows
- Experience with AWS, Lambda and AWS serverless
