Our client, a leading global investment firm, is hiring a Senior Market Data Engineer (C++) to join a core technology group supporting live trading systems. This is a hands‑on role focused on building and operating high‑performance, real‑time market data infrastructure used by multiple trading teams across asset classes. You will take ownership of critical market data components, working on feed handling, data normalisation, distribution, and integration with downstream trading and risk systems in a latency‑sensitive environment.
What you'll do:
- Design, build, and evolve low‑latency market data systems in modern C++
- Build and maintain feed handlers for both direct exchange connections (e.g. FIX, FAST, ITCH, OUCH) and vendor feeds
- Own key parts of the market data lifecycle, from ingestion through distribution and consumption
- Implement robust data quality, monitoring, alerting, and validation frameworks to ensure integrity of tick data
- 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
- 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
