Senior C++ Low-Latency Developer | UK, Netherlands or France|Remote

  • Locations: United Kingdom, Netherlands, or France
  • Work model: Fully remote
  • Employment: 12-month contract

  • Conversion: Opportunity to convert to permanent by mutual agreement
  • Level: Senior Individual Contributor
  • Work authorization: Existing right to work in one of the listed countries of residence required

About the opportunity

  • Join a sophisticated financial technology environment building high-performance trading infrastructure
  • Work on greenfield systems processing high-throughput financial market data
  • Design and develop performance-critical software using modern C++
  • Own technical delivery from architecture through testing and production deployment
  • Solve complex latency, networking, concurrency, and distributed-systems challenges
  • Work in a senior hands-on engineering position rather than a management role

What you'll own

  • Design and build low-latency distributed systems for financial market data
  • Develop performance-critical components using modern C++
  • Own architecture, implementation, testing, optimization, and deployment
  • Build systems supporting high-throughput and latency-sensitive workloads
  • Optimize application performance across CPU, memory, networking, and concurrency
  • Work with TCP, UDP, multicast, messaging, queuing, and Pub/Sub architectures
  • Translate complex or ambiguous requirements into practical engineering solutions
  • Balance rapid delivery with production-grade reliability and scalability
  • Build comprehensive unit, integration, end-to-end, stress, and performance tests
  • Collaborate with technical and business stakeholders throughout the development lifecycle

What we're looking for

  • Approximately 6+ years of professional C++ engineering experience
  • Genuine production experience building low-latency systems
  • Strong expertise in C++17 or newer, with C++20 strongly preferred
  • Excellent understanding of modern C++ fundamentals and performance characteristics
  • Strong computer science fundamentals
  • Deep understanding of algorithms, data structures, and complexity
  • Experience designing high-performance or distributed systems
  • Strong knowledge of networking and communication protocols
  • Experience with latency optimization and performance tuning
  • Production experience within traditional financial markets
  • Background in a proprietary trading firm, market maker, hedge fund, investment bank, or comparable electronic-trading environment
  • Strong communication and stakeholder-management skills
  • Ability to operate independently in technically demanding environments

Particularly valuable experience

  • Direct market-data engineering experience
  • Feed-handler or ticker-plant development
  • Electronic or automated trading systems
  • Exchange connectivity
  • FIX or ITCH protocols
  • Order-book infrastructure
  • Smart order routing
  • Tick-to-trade optimization
  • Lock-free programming
  • Kernel-bypass networking
  • Solarflare / Onload
  • DPDK
  • NUMA-aware architecture
  • Cache-aware system design
  • High-availability and failover systems
  • Idempotency and ACID guarantees

Strongly preferred background

  • Proprietary trading
  • Market making
  • High-frequency trading
  • Systematic hedge funds
  • Investment-bank electronic trading
  • Production market-data infrastructure
  • Performance-critical financial systems

This role may not be the right fit if you

  • Do not have genuine production low-latency C++ experience
  • Have primarily academic or research-based C++ experience without production systems ownership
  • Have no professional exposure to trading or financial-market infrastructure
  • Have low-latency experience primarily within cryptocurrency trading environments rather than traditional financial markets
  • Prefer management responsibilities over hands-on engineering
  • Are not comfortable joining through an initial 12-month contract
  • Are currently based outside the United Kingdom, Netherlands, or France
  • Require visa sponsorship to work from your country of residence

What you'll get

  • Greenfield engineering ownership
  • Exposure to highly sophisticated financial systems
  • Challenging modern C++ development
  • Complex low-latency and distributed-systems problems
  • High-throughput financial market-data workloads
  • End-to-end ownership from architecture to production
  • Fully remote work across the UK, Netherlands, and France
  • Potential transition into a permanent position after the initial contract
  • Opportunity to work on technically demanding systems where engineering performance directly matters
