C++ Software Engineer (Market Data & Execution) – APAC
Location: Hong Kong / Shanghai (Relocation support available) Type: Full-Time Compensation: Highly competitive (Base + Performance)
About the Client
Our client is a premier global proprietary trading firm and active market maker, operating at the highest tier of high-frequency and systematic trading. They are currently making a massive, greenfield investment to scale their APAC trading architecture.
This is a highly confidential search. Client details will be disclosed to qualified candidates upon initial screening.
The Opportunity
We are seeking elite, high-agency C++ engineers to take direct ownership of market data ingestion and ultra-low-latency execution platforms. This is not a maintenance or back-office role. You will work directly alongside the trading desks to build systems that drive PnL.
We are looking for two specific profiles:
- The Market Specialist: An engineer who doesn't just build connectivity for maintenance, but deeply owns, optimizes, and exploits quirky exchange features and protocol micro-syntax for low-latency advantages.
- The Front Office Generalist: A high-agency engineer who thrives sitting directly on the trading desk, collaborating with Tier 1/Tier 2 execution traders to drive business outcomes.
What You'll Do
- Greenfield Development: Design and build next-generation low-latency market data feed handlers and order execution gateways from scratch.
- APAC Market Connectivity: Manage high-performance connectivity for APAC exchanges (HKEX, SGX, JPX, ASX, etc.), including protocol parsing, multicast sequencing, and order book reconstruction.
- Direct Desk Collaboration: Work shoulder-to-shoulder with quants and traders to understand market microstructure and translate business needs into rapid technical solutions.
- Performance Tuning: Push the limits of modern C++ (C++17/20), using lock-free data structures, kernel bypass networking (VMA/DPDK), NUMA awareness, and CPU pinning to eliminate microseconds of latency.
- Production Ownership: Monitor, troubleshoot, and optimize systems in a live production environment under strict exchange deadlines.
The Hard Requirements (Strict Filters)
To be considered, you must meet the following criteria:
- Firm Type: You must currently (or recently) work at a Tier 1/2 Prop Shop, Top HFT firm, or a smaller proprietary shop with active high-frequency/execution trading. Note: We cannot consider candidates from Investment Banks, Platform Providers, Commercial Vendors, or pure Mid-Frequency (MFT) / Back-Office HFT roles.
- Experience: 6 + years of hands-on C++ development. (We are not considering junior candidates <6 years, nor overly senior/legacy candidates who are removed from day-to-day hands-on coding).
- Asset Class: Execution trading experience in APAC Single Stocks, ETFs, or Futures. Alternatively, we will consider candidates with execution experience across 2 asset classes (e.g., Crypto + FI, FX + FI) who are eager to adapt.
- Location: Open to Hong Kong or Shanghai. We are also fully open to candidates in US/EU markets with high ownership and desk-facing experience who are willing to relocate to APAC.
Why This Role?
- True Greenfield: Join at an inflection point. Build rapid, build-to-market systems without legacy friction.
- Broad Scope: No rigid silos. Expand your scope from pure connectivity into pricing, strategies, and execution.
- Flat Culture: Led by an active, hands-on IC manager. A collaborative, highly technical desk culture where high agency is rewarded.
