Our client is building the next generation of execution and order management (EMS/OMS) infrastructure for global commodities trading. You will join a small, fast-moving engineering team designing and delivering a cloud-native trading platform from the ground up, tightly integrated with risk, pricing, and market data systems to support high-performance trading environments.
This is a senior, hands-on role for an engineer who wants end-to-end ownership — from low-level protocol integration through to distributed execution services and trader-facing tooling.
- Develop low-latency, distributed execution services with a strong focus on correctness, resilience, and performance under load.
- Collaborate closely with traders, quants, and risk engineers to translate trading workflows and execution strategies into robust production systems.
- Ensure seamless integration with risk systems, including pre-trade checks, position tracking, and post-trade processing.
- Proven experience building execution systems and/or order management systems in production.
- Strong systems engineering fundamentals, including concurrency, distributed systems, networking, performance, and correctness under pressure.
- Production experience in at least one of C++, Rust, or Python, with willingness to work across multiple languages.
- Demonstrated ability to deliver production systems with a strong bias towards shipping, iteration, and user feedback.
- Familiarity with distributed data and event-driven systems.
- Experience with observability, monitoring, testing, and production incident response in live systems.
- Experience in commodities markets (energy, metals, agriculture, freight) or other complex, multi-venue asset classes.
- Exposure to real-time risk systems, including pre-trade controls and position/PnL infrastructure.
- Experience with columnar databases such as ClickHouse.
