• 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.

‍

• 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.

‍

• 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.
