We are expanding our Datacentre Operations team in Singapore and are seeking an experienced datacentre engineer, ideally with a background in networking and/or systems administration, and proven low-latency trading infrastructure experience, to help run the physical layer of XTX’s datacentre infrastructure.

The role combines hands-on physical datacentre work including server racking, cabling, power management, component integration, supporting network deployment, APAC colocation project management in close collaboration with the Trading Development and Procurement teams.

The position is based in our Singapore office but will require occasional international travel to datacentres predominantly based Asia.

• You will lead and execute deployment of physical infrastructure in APAC datacentres primarily, and support datacentre operations activities globally.
• You will supervise and execute large projects (e.g., colocation setup and expansions, moving large amounts of equipment between sites) and maintain our datacentres (e.g., replacing failed components). 
• You will be responsible for installing and maintaining a well-ordered datacentre infrastructure (e.g., designing, installing, and maintaining labelled, structured cabling, or power, space and cooling capacity monitoring and expansion). 
• You will perform server integration work (e.g. fitting PCIe cards, NICs, etc into servers), hardware refreshes and failed component replacements. 
• You will coordinate with third parties regarding infrastructure support. 
• Produce and maintain operational runbooks, install guides, test plans and post-change verification; review and approve changes. 
• Assist with inventory and logistics tasks as needed to support deployments (secondary responsibility, not a primary focus). 

• 5+ years working in datacentres or infrastructure operations. 
• Hands-on experience with switches/routers and low-latency network design (experience with Cisco, Mellanox, and Arista preferred). 
• Proven experience building/operating low-latency trading infrastructure and APAC colocation projects. 
• Network routing knowledge: BGP, OSPF and multicast routing (implementation and troubleshooting). 
• Comfortable working inside servers: component installs, PCIe cards, firmware updates, and hardware diagnostics (experience with Dell servers a plus). 
• Hands-on experience with fibre optics, transceivers (SFP/SFP+/QSFP/DWDM) and optical networking fundamentals. 
• Strong change management, documentation and verification discipline. 
• Excellent communication skills for vendor coordination, exchange/Broker integration and remote-hands instruction. 
• Due to the nature of our trading, some work would necessarily have to happen during weekends, as such flexibility to work on Saturdays (with time-off in lieu) or a willingness to work a shifted week (for example Tuesday through Saturday) would be necessary. 
• Fluent in both Mandarin & English.
