Avanti Recruitment is working with a growing, technology-led business based in Slough, that is undergoing a major systems transformation. As part of this programme, they are looking to hire a Senior .NET / C# Developer to play a key role in evolving a large-scale legacy platform and supporting its transition from an on‑premise desktop WinForms environment to a modern, .NET Core, cloud‑based architecture.
This is a great opportunity for someone who enjoys solving complex engineering challenges and has experience moving legacy or desktop‑based applications towards modern web and cloud platforms. You will be joining at an important stage of the transformation, with around 40 projects in the pipeline, giving you the opportunity to influence technical direction and make a genuine impact on the future of the platform.
The role will involve working closely with the CTO, Head of Engineering and the original software author to understand, enhance and evolve a complex application used across the wider engineering team. You will improve and progressively enhance an established C# .NET WinForms Desktop codebase.
The business is open to hybrid working, but they would ideally like someone who can attend onsite regularly during the early stages of the project for collaboration, knowledge sharing, planning and technical workshops. You will be expected in the office 3 times a week to begin with, and the possibility of 1‑2 days in office later down the line.
You could be the ideal candidate if you want to understand the business, enjoy collaborating with stakeholders, can challenge ideas constructively, enjoy solving difficult problems and like being part of a friendly team with regular socials. If you prefer just coding in isolation with very little interest in the wider business or collaboration then this won’t be suitable for you.

- Migrating legacy systems
- React or JavaScript exposure
- Experience introducing testing, deployment improvements or modern engineering practices into existing systems would be highly advantageous.
- AI Exposure / Python would be beneficial (For future plans)
This is an opportunity to shape a long‑term transformation programme, with high‑level of technical ownership and influence. This role will require greenfield thinking within an established business, and you will get direct access to leadership and architecture decisions. You will be part of a small, collaborative engineering team, with long‑term progression opportunity as the technology function grows.
Salary is up to £80,000 (potential flex).
