Quantitative Developer – Early London Hire (Front Office) - London - Multi-Strategy Hedge Fund - Up to £400k TC

A leading global investment manager (~$25bn+ AUM) is building out its London technology platform and hiring a key Quantitative Developer as part of that expansion.

This is a front-office role reporting directly to the Head of Development, working closely with portfolio managers and trading desks across London and Europe.

Today, the majority of the engineering team sits in the US. London is a strategic growth hub — and this hire is expected to become the go-to engineer on the ground, owning relationships with PMs and traders and driving the build-out of local capability.

The Role

This is a highly hands-on role focused on rebuilding and scaling core trading and risk infrastructure.

Key areas of focus:

  • Building and evolving real-time PnL and risk systems (moving away from slower, batch-driven workflows)
  • Designing pricing and risk infrastructure (scenario analysis, stress testing, margin replication)
  • Working directly with PMs and quants to productionise trading signals across asset classes
  • Developing data pipelines and interactive tooling for portfolio managers
  • Play a critical role in designing, implementing, enhancing, monitoring and supporting a research, back-testing and analytics platform for discretionary and systematic trading desks
  • Collaborate with Quants/researchers to understand their framework and infrastructure needs and translate them into technical solutions.
  • Acting as the primary technical counterpart for London-based desks, bridging trading and engineering

You’ll be solving problems around data scale, latency, and system reliability, in an environment where requirements are often loosely defined and speed of iteration matters.

What They’re Looking For

  • 5+ years in a front-office or trading-aligned engineering role
  • Strong Python (NumPy, Pandas) with solid software engineering fundamentals
  • Experience working with market data, time-series data, or real-time systems
  • Strong stakeholder skills — comfortable working directly with traders and PMs
  • SQL proficiency; exposure to additional languages (C#, R, etc.) beneficial
  • Background in a quantitative discipline (CS, Maths, Physics, Engineering, etc.)

Why This Opportunity

  • True ownership in London – front‐office build‐out, not a satellite support role
  • Direct impact on trading – systems you build are used daily by PMs and traders
  • Clear mandate – become the key engineering contact for European desks
  • High autonomy – low bureaucracy, fast iteration with direct desk feedback
  • Strong global platform – backed by an established US engineering team
  • Design and implement a firm‐wide, service‐oriented research and analytics platform for discretionary and systematic desks
  • Monitor and tune infrastructure for performance, efficiency and cost‐effectiveness
  • Integrate new technologies and tools to push research capabilities forward
  • Provide technical support and guidance to quant, research and PM teams
  • Leverage existing expertise while expanding your skill set on a firm‐wide research platform

Why Join

  • Opportunity to move legacy or batch workflows toward real-time systems
  • Work with large-scale, multi-asset time-series data
  • Blend of quant dev + systems engineering + stakeholder-facing work
  • Early-stage London build with real influence over architecture and tooling decisions
