C# Developer - Front Office Trading

Are you a C# developer who enjoys being close to the action rather than several layers removed from the people using your software?

What about working directly alongside a trading desk, where you can see the impact of what you build - sometimes immediately?

You''ll be joining a front-office technology environment supporting traders, combining software development with the kind of rapid problem-solving that comes from sitting alongside your users.

This isn''t a role where every requirement arrives neatly packaged in a ticket.

A trader may come to you because an application isn''t behaving as expected, they need a tool adapting for a particular trade, or something needs investigating quickly. You''ll need to understand what they''re trying to achieve and work out the technical answer.

Alongside this, you''ll spend time developing and improving the tools used by the desk, predominantly using C#/.NET, with Python, VBA and Excel also forming part of the wider environment.

If you enjoy understanding the why behind what you''re developing, you''ll get plenty of that here. You''ll be working with the people making the trades rather than simply receiving requirements further down the line.

You''ll need previous experience within a trading or front-office environment and enough financial markets knowledge to comfortably understand conversations around Swaps, Bonds and/or Equities.

You''ll also need to be comfortable with pressure. When a trader has an issue affecting what they''re trying to do, they''ll want an answer quickly. This will suit someone who enjoys that immediacy rather than wanting to work quietly through a development backlog.

Technically, C#/.NET is the key requirement. Experience with Python, VBA or Excel would add to your suitability, but your ability to understand trading environments, solve problems and communicate directly with traders is equally important.

This role is a hybrid position based in central London.

We''re looking to move quickly, so if you''ve worked in front-office development and this sounds like your kind of environment, send over your CV and I''ll be in touch.
