You’ll be working inside one of the largest FX franchises in the world, engineering ultra-low latency pricing systems used by traders, quants, and clients across every major currency pair.

What makes this role different

• True low latency engineering - not just “event-driven” on paper
• Front-office exposure - direct interaction with traders & quants
• High-impact systems - pricing engines, market data, execution flows
• Modernisation at scale - re-architecting legacy into high-performance, distributed systems
• Hands-on at SVP level - still coding, still solving hard problems

The work

You’ll lead from the front-both technically and strategically:

• Design and build ultra-low latency FX pricing systems
• Optimise performance across JVM, CPU, memory, and network layers
• Work closely with trading desks & quant teams to deliver real-time solutions
• Drive system re-engineering (legacy → modern, high-performance architecture)
• Mentor and shape a high-calibre engineering team
• Influence architecture across global FX technology

What they’re looking for

• Strong background in low latency / high-performance Java
• Experience in pricing, market data, or execution systems (FX ideal, not essential)
• Deep understanding of:
  • GC tuning / low allocation design
  • Multithreading / concurrency
  • Network protocols / messaging
  • System-level performance optimisation
• Proven track record of:
  • Building or re-engineering business-critical systems
  • Working closely with front-office stakeholders
• Comfortable operating as a hands-on technical leader

You’ll lead from the front-both technically and strategically:

• Design and build ultra-low latency FX pricing systems
• Optimise performance across JVM, CPU, memory, and network layers
• Work closely with trading desks & quant teams to deliver Real Time solutions
• Drive system re-engineering (Legacy - modern, high-performance architecture)
• Mentor and shape a high-calibre engineering team
• Influence architecture across global FX technology

What they’re looking for

• Strong background in low latency/high-performance Java
• Experience in pricing, market data, or execution systems (FX ideal, not essential)
• Deep understanding of:
  • GC tuning/low allocation design
  • Multithreading/concurrency
  • Network protocols/messaging
  • System-level performance optimisation
• Proven track record of:
  • Building or re-engineering business-critical systems
  • Working closely with Front Office stakeholders
• Comfortable operating as a hands-on technical leader

Overview

Currently, delivery teams seeking to build or procure digital products within the Cabinet Office must navigate a highly complex and fragmented assurance landscape. Critical compliance rules and policies are often hidden or difficult to locate, and the manual nature of the process frequently traps teams in frustrating administrative bottlenecks and dependency loops.

To address this, we are developing a “Digital Assurance Navigator” platform that translates these complex policies into an automated, machine-readable rules engine. Because we are currently in the Alpha phase, we are prototyping an intelligent, AI-driven interface that interviews users about their project and dynamically generates a tailored, step-by-step checklist of exactly what is required to achieve compliance.

We are seeking a Lead DevOps Engineer to help us map this complex ecosystem and design an intuitive, user-centred journey that removes friction and guides teams safely from inception to deployment

You thrive in working in tribes and squads that focus on specific products and projects - and depending on your strengths and interests, you’ll have the opportunity to move between them.

While we’re looking for professional skills, culture is just as important to us. We understand that everyone’s unique - and that diversity of thought, experience and background is what makes a good team, great. By bringing people with different points of view together, we can represent everyone and truly reflect the communities we serve. This way, there’s scope for you to make a huge difference - on us as a company, and on our clients and business partners around the world
