🚀 C# Software Engineer | £160k+ | Quant Trading | London

I’m working with an elite quantitative trading firm that’s looking for strong C# Software Engineers to join a highly technical team.

This is a particularly interesting one for anyone who enjoys building things where performance actually matters.

You’ll be working on genuinely challenging engineering problems, using some of the newest technology in the industry and working alongside some seriously smart people.

It’s also a very flat structure, which means far less of the usual corporate nonsense.

You won’t be spending half your week in meetings about meetings, waiting for someone three levels above you to approve an idea you had two weeks ago. You’ll have real ownership, direct access to senior people and plenty of freedom to make technical decisions.

The role

Build high-performance software

You’ll be working with C# in a highly performance-focused environment, building and improving systems where speed, reliability and scalability genuinely matter.

🧠 Solve difficult engineering problems

This isn’t a role where everything has already been figured out. You’ll be tackling interesting technical challenges and working out how to make things faster, more efficient and more robust.

⚡ Work with seriously good tech

The firm invests heavily in technology and infrastructure, giving engineers the opportunity to work with modern tooling and solve problems at a scale you simply don’t see in most environments.

Have genuine ownership

You’ll be trusted to make decisions and take projects from idea through to implementation. Less hand-holding, more opportunity to actually build.

Progress quickly

The structure is deliberately flat. Perform well, take on more responsibility and your career and compensation can move quickly with you.

😎 Work hard, have a life

High standards, smart people and interesting problems, without the 80-hour weeks being worn as a badge of honour. Good work/life balance, a fun culture and a supportive office.

Who we’re looking for

🧑 Strong C# Software Engineers with a genuine passion for engineering.

🧠 Engineers who enjoy solving complex problems and getting into the detail of how systems work.

⚡ People who care about performance, scalability, clean code and building things properly.

Experience in high-performance, low-latency or technically demanding environments would be interesting, although the wider engineering background is important too.

🚀 Ambitious engineers who want responsibility, technical ownership and the opportunity to progress quickly.

🤝 People who enjoy working with very smart teams without needing a huge hierarchy around them.

If you’re a strong C# engineer and fancy working somewhere where the technology is genuinely interesting, the money is serious and the bureaucracy is minimal , this is one worth taking a closer look at.
