A leading global hedge fund is building a greenfield financial analytics library and high-performance distributed systems from concept to launch - and is hiring senior C++ engineers to design and own them. Fully remote across the UK, the Netherlands, and France, on a 12-month contract that converts to a permanent role.

You'll build best-in-class distributed systems that process high-throughput financial market data, owning architecture, code, testing and deployment end to end - genuinely cutting-edge modern C++ in one of the most demanding engineering environments in the industry.

What You'll Do

Engine development: design and build best-in-class distributed systems that process high-throughput financial market data.
Full-lifecycle ownership: drive system architecture, coding, testing (unit, integration, end-to-end, stress, performance) and deployment.
Execution & trade-offs: translate complex, ambiguous requirements into clear tasks, balancing MVP vs. enterprise-grade and speed-to-market.

Requirements

Modern C++: mastery of C++20 fundamentals (lambdas, move semantics, reference types, virtual/static functions), with strong CS fundamentals - design patterns and algorithmic complexity across imperative, OO and functional styles.
Distributed systems: solid grasp of load balancing, HA / failover, inter-service communication, idempotency and ACID guarantees.
Networking & protocols: hands-on with messaging / queuing, Pub/Sub, TCP, UDP and multicast. Market-data protocols (FIX, ITCH) preferred.
Optimization & architecture: proven system-architecture design, latency optimization and performance tuning for trading environments.
Collaboration: strong stakeholder management, multi-disciplinary teamwork and a continuous-learning mindset.
A background in a trading firm, hedge fund, or investment bank is strongly preferred.

Nice to Have

Direct market-data / feed-handler / electronic-trading experience.
Kernel-bypass networking, NUMA- and cache-aware design, lock-free programming.

The Details

Location: fully remote - UK (primary), Netherlands, or France.
Engagement: 12-month contract, convertible to a permanent role by mutual agreement.
Level: senior individual contributor - a hands-on, greenfield build role, not a management position.
