C# Developer – Elite Systematic Hedge Fund – London – Multiple Headcount – Up to £350k TC

One of the world’s most progressive systematic hedge funds is scaling a core engineering function and hiring multiple C# developers to build the platforms that power research, trading, and firm-wide decision making.

This is not a narrow “support” seat. You’ll be writing production-grade software that sits close to the investment process, working with quantitative researchers, engineers, and stakeholders across the firm to deliver high-impact tools at speed. With a new growth mandate in place, the team is expanding materially — multiple hires, real greenfield builds, and visible ownership.

The Role

As a C# Developer, you’ll help design and build modern systems across the fund’s technology estate, including:

• Core platform services supporting systematic research and live trading workflows
• High-performance data & analytics tooling (pipelines, APIs, services, internal frameworks)
• User-facing applications for researchers, PMs, and senior stakeholders (dashboards, micro-apps, visualisations)
• Automation & engineering enablement: improving developer experience, reliability, and speed of iteration

You’ll operate in a lean, high-calibre environment where engineers ship meaningful work, get direct feedback, and see the impact of what they build.

Tech Stack

• Backend: C# / .NET
• Frontend: React / Angular (depending on team)
• Data: SQL Server (plus broader data tooling in the stack)
• Engineering: modern CI/CD, strong testing culture, clean architecture patterns

What They’re Looking For

• Strong software engineer with C#/.NET experience (full-stack experience welcome, not mandatory)
• Solid fundamentals: clean design, performance awareness, testing, maintainability
• Comfortable partnering with technical and non-technical stakeholders
• Experience in finance is helpful, but not required — they hire for engineering excellence
• Strong academic backgrounds (CS, Maths, Physics, Engineering, etc.) are valued

Why This Role Stands Out

• Build software that directly supports a top-tier systematic investment business
• Multiple headcount due to growth — real expansion and greenfield work
• High ownership, low bureaucracy, fast iteration
• Work with genuinely top-end engineers and quantitative teams
• Market-leading compensation in a high-performance environment

If you’re looking for a high-impact C# role in a world-class systematic fund — with modern engineering, serious ownership, and strong comp — this is one of the best seats in London right now.
