Job description

Senior C# Developer – Investment Technology – London

Our client is one of the most exciting technology companies operating within the Investment Management space. Having grown rapidly into an international business, they are now at a particularly exciting stage as they continue to scale their innovative platform, client base and engineering teams.

They are looking for a talented C# Developer to join a highly client-facing engineering team. This isn't a traditional development role – you'll combine hands-on C# engineering with solution design and end-to-end delivery, working directly with sophisticated financial institutions to solve genuinely complex technology and data problems.

Strong Investment Management knowledge is essential. You'll need to understand investment products and Asset Classes, particularly Equities and Fixed Income, together with the trade lifecycle and how these are used within the investment world.

Successful candidates will have significant commercial C# experience alongside genuine Investment Management domain expertise. You should be comfortable discussing different Asset Classes with clients and understand the key characteristics of Equities and Fixed Income. General retail banking experience without this investment knowledge is unlikely to be sufficient.

Experience with Python, SQL, PMS, OMS, EMS, Trade Operations, Risk, Portfolio Compliance, CI/CD and Docker would be beneficial. Exposure to additional Asset Classes beyond Equities and Fixed Income, including ETDs, OTCs and Alternatives, would also be advantageous.

This is a fantastic opportunity for a senior C# engineer who wants to remain technically hands-on while joining an ambitious, innovative FinTech at a genuinely exciting point in its growth. You'll gain significant client exposure, real ownership and the opportunity to use your Investment Management expertise to solve challenging problems across multiple Asset Classes.

Benefits include bonus, comprehensive private healthcare, professional training, gym discounts, 25 days' holiday plus bank holidays, additional holiday purchase, birthday off and hybrid working.

Location: London / Hybrid Working
