About this role
Jane Street's London office is seeking a Technical Operations Engineer to oversee the building systems that keep its trading floor and critical facilities running around the clock. You'd own hands-on responsibility for electrical, mechanical and building services infrastructure—from HVAC and power systems to fire prevention and building automation—working to maintain the 24/7 reliability that a high-performance trading environment demands. The role spans routine maintenance and planned upgrades through to emergency response, vendor management, and continuous optimisation of how these systems perform.
This position suits someone with at least five years in mission-critical facility operations, whether in banking, trading floors, data centres or similar environments where downtime is costly. You'll need solid grounding in building services and plant infrastructure, comfort troubleshooting independently, and the ability to read technical documentation and commissioning scripts. Equally important is technical fluency with computer systems and building management platforms, since you'll be learning new software and working in an IT-centric setting alongside colleagues from different departments.
The role includes on-call rotation for nights and weekends to respond to critical emergencies. Jane Street values strong communicators who can explain complex issues clearly to both technical and non-technical audiences, and people who can adapt, prioritise effectively and grow within a collaborative environment. Fluency in English is required.
