Network Engineer — Ultra-Low-Latency Trading Infrastructure

Location : Singapore · Type : Full-time · Team : Trading Infrastructure / Networking About the Role Dharmacapital Pte. Ltd. is a proprietary high-frequency trading firm seeking a Network Engineer to design, build, and operate the ultra-low-latency network infrastructure that underpins our trading systems. You will own the network path end-to-end — from exchange cross-connects and colocation switching to NIC tuning and kernel-bypass — where latency is measured in nanoseconds and every hop matters. This is a hands-on engineering role with direct, measurable impact on trading performance. Key Responsibilities Design, deploy, and operate low-latency network infrastructure across multiple exchange colocation facilities and data centers. Optimize end-to-end latency across the full stack and continuously hunt down nanoseconds. Manage exchange connectivity, cross-connects, and market data delivery, including UDP multicast feed handling, gap/arbitration, and feed redundancy. Deploy and tune Layer 1 / low-latency switching and low-latency L2/L3 networks. Implement and maintain precision time synchronization and ensure accurate, traceable timestamping across the environment. Work with kernel-bypass and accelerated networking technologies and support FPGA-based networking where applicable. Build and maintain latency monitoring, nanosecond-resolution packet capture, and analysis tooling. Coordinate and validate long-haul, microwave, and millimeter-wave connectivity between trading venues with carriers and vendors. Automate configuration, provisioning, and deployment and maintain infrastructure-as-code. Provide capacity planning, change management, and 24×7 on-call incident response for trading-critical systems. Required Qualifications Bachelor's degree in Computer Science, Electrical Engineering, or equivalent practical experience. 3+ years of network engineering experience, ideally in low-latency, financial, or HFT environments. Deep, practical knowledge of TCP/IP, UDP multi…
