Senior C# Developer – Investment Technology – London
(Tech stack: C#, Investment Management, Asset Classes, Fixed Income, Equities,.NET, Python, SQL, OMS, EMS, Docker, CI/CD)
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.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.

Only hits

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.
