Job Description:

BMS & OT Systems Engineer - London - £90,000
Critical Environment / Financial Services

Are you a BMS engineer who's ready to step up into a resilience & security-focused role, without losing the hands-on controls work you enjoy?

I'm working with a major real estate services provider on a newly created role supporting the BMS/OT estate across a critical, high-profile London portfolio (banking & financial services client). This isn't a desk-based cyber role - it's a controls engineering role with cyber-awareness built in.

What you'll be doing:

• Acting as engineering lead for BMS/OT platform health across a multi-site portfolio
• Fault diagnosis, performance optimisation and lifecycle work (upgrades, controller refresh, server/workstation replacement)
• Commissioning, tuning and validating control strategies and alarms
• Owning OT/BMS network documentation, topology, panel drawings, asset registers
• Embedding practical security controls: patch coordination, access management, backup/recovery assurance
• Managing vendor delivery and technical governance (change control, method statements, as-built docs)

What's on offer:

• £90,000 + comprehensive benefits
• Funded professional development / technical training
• Leadership responsibility across three flagship London properties
• Exposure to premium commercial real estate across London/UK
• A genuine shot at shaping OT engineering strategy for a global real estate leader

What we're looking for:

• Strong hands-on BMS/industrial controls background, ideally multi-site
• Working knowledge of BACnet, Modbus, OPC, LonWorks or similar
• Comfortable owning platform lifecycle, servers, databases, backups
• Vendor certs a bonus (Trend, Siemens, Schneider, Honeywell, Tridium Niagara)
• IEC 62443 / NIST / CIS awareness advantageous, not essential
