About the Position

We are looking for an experienced Data Centre Engineer who can help our team keep Jane Street’s data safe and accessible around the clock, involving a mix of hands‑on work in our data and colocation centres, process thinking and project management.

Your work will mostly involve designing, building, scaling and performing daily upkeep in our regional data and colocation centres. You’ll also get to collaborate with really talented people from all different areas of expertise across Jane Street to optimise our data environments and prevent major problems before they happen.

You will join an interdisciplinary team made up of several groups across Jane Street, including our Network, Server, Facilities Engineering, Market Data and Trading teams, along with some external data centre operators, colocation and smart hands service providers, and cabling, hardware and telco vendors. Together, you will:

• Design plans for new equipment deployments using data centre best practices
• Coordinate logistical tasks across locations, including procurement, shipping, moving and keeping inventory of our equipment, cabling and parts
• Install and configure server OS in a PXE environment (fundamental Linux knowledge is required to deploy our network equipment)
• Install, cable, configure and troubleshoot different types of network and server equipment
• Ensure that all our data centres uphold the highest standards in terms of security, organisation, documentation, safety, cleanliness and supply management

This role provides on‑location services that are crucial to our daily operations in London, as well as impact the operations of our remote locations across EMEA.

About You

While there’s no fixed set of skills required for this role (we can teach you what you need to know), here are some of the things we’re looking for:

• Ideally 5+ years of experience working in a data centre environment with a strong understanding of data centre best practices, cabling methodology and managing vendors
• A self‑starter mindset; someone who takes initiative, gets the job done and is always on the lookout for ways we can do things better
• A clear communicator with excellent people and project management skills
• Knowledge of networking fundamentals; including how to switch and rout protocols and troubleshoot Layer 2 and 3 connectivity issues
• Proficiency in a Linux environment (Scripting skills in Bash or Python are a plus)
• Experience deploying a variety of server and network hardware (e.g., Dell, Cisco, Arista, Ciena, Corning, Ortronics products)
• Ability to design, deploy, test and troubleshoot both copper and fibre cabling
• Willingness to travel and work evenings/weekends
• Fluency in English is required
