Senior Front-End Engineer - Angular - React - C# - Elite Systematic Hedge Fund - London - Multiple Hires - Up to £300k TC

A world-class systematic hedge fund is expanding a core engineering team in London and hiring multiple Senior Front-End Engineers (front-end leaning, but full-stack capable) to build polished, high-impact web applications used by external clients and senior internal stakeholders.

This is a high-visibility role in a small, high-calibre team (currently 4 developers) with a clear mandate to scale. Engineers will take ownership of specific products and workstreams as the function grows.

The Role

You’ll design and build modern, user-centric web platforms including:

  • Investor portals and external reporting platforms
  • Client-facing dashboards, visualisations, and bespoke reporting tools
  • High-quality UI components and micro-apps used across the business

While the role is front-end focused, you’ll also contribute to backend services and data-driven features in C#/.NET, helping deliver end-to-end functionality.

Who You’ll Work With

You’ll collaborate closely with teams across operations and governance functions (e.g., middle office, accounting, and compliance), alongside engineers in a lean environment where projects move quickly and your impact is highly visible.

Tech Stack

  • Frontend: Angular (React also welcomed)
  • Backend: C# / .NET
  • Database: SQL

What They’re Looking For

  • Strong front-end engineer with proven experience delivering polished web applications
  • Comfortable taking ownership of UI architecture, component design, and user experience
  • Good working knowledge of C#/.NET (or a willingness to deepen backend skills)
  • Experience building external / client-facing platforms is a major plus
  • Finance knowledge helpful but not required
  • Strong engineering fundamentals: clean code, testing mindset, performance awareness

Why This Role Stands Out

  • Build highly visible, front-facing products in a sophisticated engineering environment
  • Multiple headcount due to growth (not backfill)
  • Real ownership and autonomy in a low-bureaucracy team
  • London HQ in Knightsbridge with exceptional onsite amenities (gym, healthcare support, free breakfast/lunch, barista, roof terrace, and regular team events)

If you’re a senior front-end engineer who enjoys building refined user experiences and wants to stay close to high-performance systems—with meaningful ownership and excellent compensation—this is one of the strongest opportunities in London right now.
