Network Engineer

About the Role

We are seeking a skilled Network Engineer to design, build, and maintain the low-latency network infrastructure connecting our trading systems to exchange colocation environments (including NSE colocation). This role operates at the intersection of exchange connectivity, network architecture, and production infrastructure reliability, with a strong emphasis on low-latency design, multicast market data delivery, and hands-on ownership of our colocation rack. You will work closely with our trading infrastructure team to ensure our systems have fast, reliable, and resilient connectivity to the exchange.

Key Responsibilities

• Design, deploy, and maintain network connectivity between our colocation rack and NSE trading systems
• Configure and manage BGP (unicast routing) and PIM-SM (multicast routing) for order entry and market data connectivity
• Troubleshoot and resolve network-related latency and performance issues across production trading infrastructure
• Own physical layer setup and compliance — fiber handoffs, patch cords, switch/transceiver configuration, and NSE audit readiness
• Manage out-of-band hardware management (IPMI/BMC) for remote server administration in the colo environment
• Coordinate with NSE colocation support and remote-hands teams for troubleshooting, circuit migrations, and hardware issues
• Collaborate with the trading/quant dev team on network-level latency optimization (NIC tuning, kernel bypass considerations, etc.)
• Maintain documentation of network topology, configurations, and connectivity architecture for internal reference

Requirements & Tech Stack

• Experience in network engineering, ideally in a trading, fintech, or low-latency environment
• Strong knowledge of routing protocols — BGP (eBGP), and multicast routing (PIM-SM, IGMP)
• Solid understanding of L2/L3 network design and client-server network architectures
• Hands-on experience with Cisco IOS/NX-OS or equivalent network operating systems
• Experience with datacenter/colocation network setups — fiber connectivity, patch panels, SFP/SFP+ transceivers
• Familiarity with IPMI/BMC and out-of-band server management
• Working knowledge of Linux/Unix systems administration
• Understanding of exchange connectivity concepts (market data feeds, order entry, redundancy design) — NSE experience strongly preferred

Preferred (Nice to Have)

• Direct experience with NSE colocation infrastructure or Indian exchange connectivity
• Experience with multicast market data distribution in a trading environment
• Exposure to time synchronization (NTP/PTP)
• CCNA or higher certification
• Familiarity with low-latency network tuning (kernel bypass, NIC offloading) — DPDK/Solarflare exposure a plus

Candidate Profile

• Strong systems thinker with attention to detail and reliability
• Able to work closely with trading/dev teams and leadership in a small, high-ownership environment
• Calm and methodical under pressure — network issues during market hours require fast, precise troubleshooting
• Willing to be hands-on with physical infrastructure (rack visits, cabling, hardware troubleshooting) when needed
