Job description
Senior Software Engineer (.NET/React/AWS) £650/day (Inside IR35) Manchester (Hybrid - 1-2 days per week) 6 Month Contract
We're working with a large-scale, technology-led business investing heavily in a greenfield platform build, and they need a Senior Software Engineer to play a key role in shaping it from the ground up.
This isn't a narrow Front End role.
The Front End is central to the product, but you'll be operating across the wider platform, working closely with Back End services, APIs, and cloud infrastructure to deliver a high-performance, scalable system end-to-end.
What you'll be doing:
- Building and scaling a modern React/Next.js application at the core of the platform
- Contributing to micro-frontend architecture (Module Federation)
- Working closely with Back End engineers on API design, data flow, and system integration
- Developing and integrating with .NET/C# Back End services
- Deploying and supporting applications within AWS (CloudFront, S3, etc.)
- Designing performant, scalable user experiences for a high-traffic platform
- Staying hands-on while contributing to technical direction within your squad
What they're looking for:
- Strong experience with React/Next.js in production environments
- Solid exposure to .NET/C# Back End development (APIs, services, integrations)
- Experience working within micro-frontend architectures or similar scalable Front End patterns
- Good understanding of AWS and how applications are deployed and served
- Strong grasp of API-driven architecture and frontend/backend interaction
- Experience building scalable, high-performance platforms
- Comfortable operating as a senior, hands-on engineer within a product-led team
The environment:
- Greenfield build - no Legacy constraints, built properly from day one
- Modern engineering practices across Front End and backend
- Product-led squads with high ownership and autonomy
- Platform being built at genuine scale, not a side project
If you're an engineer who enjoys owning the Front End experience while understanding and contributing to the Back End platform, this is a strong opportunity to get involved in something meaningful from the
