About the role
We are hiring a senior, hands-on C++ engineer to build and optimize the low-latency hot path for a top-tier global trading firm (name shared under NDA).
This is a headhunting search for one exceptional engineer, not a volume hire.
You will own performance-critical trading and market-data systems in production, working alongside traders and quant researchers.
Location and eligibility
- Fully remote from the UK (primary), Netherlands, or France
- You must already hold the right to work in your country of residence (no sponsorship offered)
Engagement
- 12-month contract, convertible to a full-time/permanent role after 12 months by mutual agreement
- Employment/engagement vehicle handled per country
Compensation
- Highly competitive, benchmarked to top-of-market trading-firm rates for senior low-latency engineers
- Exact range confirmed at screening
What you will do
- Design, build, and optimize the low-latency hot path for automated/electronic trading in modern C++ (C++17/20)
- Build and maintain market-data infrastructure: feed handlers, ticker plant, order-book construction, and normalization
- Implement exchange connectivity and FIX-based order flow, including smart-order-routing components
- Drive down tick-to-trade latency using lock-free data structures, cache- and NUMA-aware design, and kernel-bypass networking (Solarflare/Onload, DPDK)
- Profile, measure, and eliminate latency and jitter across the full stack
- Translate strategy and execution needs from traders and quants into performant, reliable production code
- Own components end-to-end: reliability, observability, and incident response
- Required
- ~6+ years of professional C++ engineering in production low-latency systems
- Modern C++: C++17 minimum, C++20 preferred
- Low-latency experience from traditional financial services: proprietary trading firm, market-maker, HFT shop, investment-bank e-trading desk, or systematic hedge fund
- Direct market-data, feed-handler, or electronic-trading exposure
- Hands-on with lock-free programming, multicast, low-level networking, and performance profiling
- Comfortable with fully remote work and a 12-month contract structure
- Nice to have
- Kernel-bypass (Solarflare/Onload, DPDK) and NUMA/cache-aware design
- Order book, ticker plant, smart-order-router, and exchange connectivity
- Deep tenure in a single demanding low-latency environment
- Not a fit
- Low-latency C++ experience derived solely from crypto exchanges or crypto market-makers (traditional trading backgrounds required)
- Purely academic or research C++ with no production low-latency systems
- A pattern of very short tenures with no depth in one low-latency environment
- Screening focuses on
- ~6+ years of professional C++ / low-latency engineering
- Low-latency C++ built inside traditional financial services
- Direct market-data, feed-handler, or electronic-trading experience
- Current base in the UK, NL, or FR and openness to a remote 12-month contract
