Job description

Job Description – Quant Systems Developer (Low Latency Trading)

Overview

We are looking for a highly skilled Quant Systems Developer to design, build, and optimize mid- to high-frequency trading systems for US equities and cryptocurrency markets.

This is a hands-on engineering role where you will work closely with quant researchers, traders, and infrastructure engineers to deliver production-grade, ultra-low latency trading systems operating at microsecond-level performance.

Key Responsibilities

System Design & Development

• Build and optimize ultra-low latency trading systems using modern C++ (C++17/20).
• Develop market data handlers, order execution gateways, and risk management modules.
• Create backtesting and simulation frameworks to support quant research and strategy validation.

Performance Optimization

• Profile and tune code for sub-millisecond execution and high throughput.
• Eliminate network, kernel, and serialization overheads in execution paths.
• Optimize order routing and feed handling across multiple venues and protocols (FIX, ITCH, OUCH, WebSocket, native APIs).
• Partner with quant researchers to bring strategies from research into production.
• Work with infrastructure teams on bare-metal deployments, low-latency networking, and time synchronization (PTP).

Monitoring & Reliability

• Build fault-tolerant, high-availability systems with real-time logging, monitoring, and alerting.
• Implement robust disaster recovery mechanisms for mission-critical trading operations.

Requirements

Technical Skills

• Expert in C++17/20, including multi-threading, lock-free data structures, and template metaprogramming.
• Strong experience with low-latency optimizations (NUMA, kernel bypass, RDMA, DPDK, TCP/UDP tuning).
• Deep knowledge of market microstructure for US equities and crypto.
• Familiar with market data protocols (ITCH, OUCH, FIX, WebSocket) and exchange APIs.
• Skilled in Linux systems programming and network programming.
• Hands-on experience with build systems (CMake, Bazel), profilers, and debuggers (perf, gperf, valgrind).
• Experience with real-time data processing and event-driven architectures.
• Understanding of mid-/high-frequency trading strategies and execution algorithms.
• Familiarity with risk management and real-time position tracking.

Education & Experience

• Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, or related field.
• 3–7 years of experience in low-latency trading systems or high-performance computing (HPC).

Preferred (Nice to Have)

• Experience with GPU acceleration (CUDA) or FPGA programming for ultra-low latency workloads.
• Proficiency in Python for integration scripts or data analysis.
• Knowledge of cryptography and blockchain protocols.
• Exposure to distributed systems and microservices architectures.

Soft Skills

• Strong problem-solving and debugging skills.
• Ability to thrive in a fast-paced, iterative development environment.
• Clear communication and teamwork across cross-functional teams.
• High ownership mentality with focus on reliability and performance.

What We Offer

• Opportunity to work on cutting-edge trading systems for global markets.
• Competitive package with performance-based bonuses.
• High-impact role in a fast-growing quantitative trading firm.
• Collaborative environment with quants, engineers, and researchers.

Work Schedule

• Must be available during US trading hours: 3 PM – 12 AM, Kuala Lumpur time.
