C Software Engineer (Low Latency) – Global Quantitative Trading Firm

Sydney

Why Join Us?

We’re partnered with a leading global quantitative trading firm that is growing its low latency engineering teams in APAC.

You’ll work on the critical path of a world-class trading platform. That covers both how the firm connects to exchanges and the trading logic that runs on that connection. You’ll work directly with traders and quants, and your code can go into live markets quickly, sometimes on the same day.

We’re hiring across two closely linked areas. Engineers with experience in either are encouraged to apply:

- Connectivity & Market Data: exchange gateways, order entry, and market data feed handlers
- Strategy Development: turning trading ideas into rapid, reliable pricing, quoting, and execution logic

This role requires prior trading experience, or experience in a similar industry working on latency critical software.

What You’ll Work On

- Low Latency C systems
- Exchange connectivity, order entry, and real-time market data processing across APAC markets




- Building and tuning trading strategies with traders and quantitative researchers
- Performance work at every level: profiling, kernel bypass, network and hardware optimisation
- End-to-end ownership, from design through to deployment and live production support

Required Skills

- 3 years of commercial software development, with very strong modern C
- Experience building low-latency, real-time, or high-performance systems
- Solid computer science fundamentals: data structures, algorithms, operating systems, and networking (TCP/UDP, multicast)
- Comfortable working in Linux environments

Nice to Have

- Experience with exchange protocols (FIX, ITCH/OUCH, or native binary protocols)
- Knowledge of market microstructure or electronic trading
- Python or another scripting language for tooling and analysis
- Exposure to FPGA, kernel bypass (e.g. Solarflare/OpenOnload, DPDK), or backtesting frameworks
