Market Data Engineer C++

The Client

We’re partnering with a leading global investment firm to hire a senior Market Data Engineer to help build and scale a next-generation real-time data platform supporting systematic and discretionary trading teams.

This is a high-impact role at the core of the trading technology stack, focused on delivering low-latency, high-throughput market data systems used across multiple asset classes.

The Role

You’ll design and develop a centralised market data distribution platform that handles large-scale, real-time data ingestion and delivery across the firm.

Key responsibilities include:

• Building high-performance feed handlers for direct exchange and vendor data feeds
• Designing low-latency data pipelines for firm-wide consumption
• Ensuring data quality, validation, and monitoring across real-time systems
• Developing Python-based APIs and tooling for downstream integration
• Collaborating with trading, infrastructure, and engineering teams to deliver robust production systems
• Supporting and troubleshooting live trading environments

What We’re Looking For

• 6+ years’ experience in low-latency C++ engineering
• Strong background in real-time market data systems
• Experience with exchange protocols (e.g. ITCH, OUCH, FIX/FAST)
• Deep understanding of networking (TCP/UDP/multicast) and data distribution models
• Expertise in performance optimisation, concurrency, and memory management
• Proficiency in Python for APIs and data workflows
• Experience working on high-availability, large-scale platforms

Nice to Have

• Experience with messaging frameworks (e.g. Aeron, Kafka, ZeroMQ)
• Familiarity with modern infrastructure (Docker, Kubernetes, cloud environments)
• Knowledge of financial markets (Equities, FX, Futures, Commodities)
• Exposure to observability tooling (Prometheus, Grafana)

Why Apply?

• Work on mission-critical systems at the heart of trading
• Solve complex engineering challenges in a high-performance environment
• Join a collaborative, high-calibre team with strong technical ownership
• Competitive compensation with strong upside
