- Partner closely with traders, quantitative researchers, infrastructure teams, and other engineers to gather requirements and deliver production‑ready solutions
- Provide production support, troubleshooting, and incident ownership for mission‑critical systems
- Contribute to architecture decisions, technical standards, and best practices for a central platform used firm‑wide
- Clearly communicate technical trade‑offs, progress, and risks to senior stakeholders
What we're looking for:
- Strong experience building production‑critical C++ systems on Linux
- Background in real‑time, performance‑sensitive, or distributed systems
- Experience with exchange protocols (e.g. FIX, FAST, ITCH, OUCH or similar)
- Experience working with market data feeds, tick data, or data distribution platforms
- Solid understanding of networking, messaging, and low‑latency system design
- Proven ability to own systems end‑to‑end, from design through production support
- Clear communication skills and a pragmatic, delivery‑focused mindset
