New Year, new challenge? If you are a Lead or Senior software engineer with a track record of using C#, and the .NET framework we would love to talk to you. We have been retained by our London client to help them find a senior leader for their engineering team as they look to re-engineer a highly successful platform relied on by some of the biggest names in asset management and banking. Core to the solution is their selection of C# / .NET framework to build the next generation of their software.
This is a rare opportunity to join a greenfield project as the company looks to design their runaway success application from the ground up. New stack (C#, .NET) and new architecture - this represents a great chance to put your design and programming skills to work right at the start.
Our client is a successful Fintech, underwritten by P.E. investment, growing 30% YoY, which has a very strong balance sheet and highly focused and motivated leadership team.
We are looking forward to speaking to senior and lead C#, .NET engineers with the following profile:
- A minimum of 8 years of professional software engineering experience, with extensive experience working with C# and the .NET framework.
- Comfortable working in cloud environments; our client has selected AWS, but experience with other cloud technologies - Azure, GCP is also of interest.
- Proven track record as a hands-on senior frontend engineer - you design and deliver production features while supporting team development.
- Strong software engineering fundamentals: Object-oriented programming, design patterns, SOLID principles, automated testing, CI/CD.
- API integration: Experience consuming REST APIs, handling asynchronous data, error handling, and loading states.
- Modern database knowledge: Strong SQL skills, database design, and optimisation.
You will be happy producing high-quality code and collaborating closely with key stakeholders, including Product. As a senior C# developer, you will also be comfortable guiding and mentoring more junior engineers. This is a role that comes with a high degree of autonomy and there is an expectation that you will be passionate about your craft and build that culture around you.
If this sounds like the move you are looking for in 2026, please get in touch with us and we would be happy to share further details with you.
