BMS Engineer

Janus Digital Global; Milton Keynes; On-site; GBP 45,000 - 65,000; Full time

Job summary

Janus Digital is seeking a BMS Delivery Engineer to turn physical buildings into structured data models. You will work with Project Managers and BIM Modellers to deliver static and dynamic data on live projects, and hand over platform operation through structured training.

You will train client and partner engineers to configure, operate and maintain the platform after handover, including recertification programs and ongoing support across multiple sites.

Qualifications

• HANDS-ON experience in building MEP, BIM delivery, or smart building tech.
• Ability to read mechanical/electrical drawings and identify equipment on site.
• Proficiency with BIM tools and CAD/IFC drawing interpretation.

Responsibilities

• Deliver end-to-end building data models and collect as-built drawings.
• Configure IoT data points and integrate with building models.
• Train client and partner engineers to operate the platform.
• Certify partners and run annual recertifications.
• Collaborate with PMs, BIM Modellers and Solution Architects on delivery.
• Troubleshoot BIM-to-reality discrepancies and IoT issues.
• Ensure data quality benchmarks before client submission.

Job description

About Janus Digital

Janus Digital™ is the agentic AI platform that runs the world's real assets: enterprise-grade AI agents that sense, reason, decide and act across building environments in real time. Built on 15+ years of foundational R&D and over $100M invested in platform development, we're scaling commercially on an outcome-based model with property managers, hotel operators and shopping centre administrators across the UK. From our London base, we're growing across the UK, Europe and beyond.

The Opportunity

As a BMS Delivery Engineer, you're the engineer who turns physical buildings into the structured, high-fidelity data models our agentic AI operates on, and increasingly, the engineer who trains and certifies the client and partner teams who take over platform operation after you. Working hands-on with Project Managers and BIM Modellers, you'll own delivery of both static building data and dynamic IoT data on live projects, then hand off your expertise through structured training and certification. Your work determines whether a building can run autonomously, and whether the partners who take it from there are equipped to keep it that way.

What You'll Do

• Own end-to-end delivery of building data models: as-built drawing collection, BIM verification against physical sites, spatial and MEP equipment registration, relationship mapping, QR code tagging and final client acceptance
• Execute the full IoT delivery workflow: point list encoding, binding table preparation, gateway configuration and protocol commissioning across BACnet, Modbus, MQTT, OPC UA and KNX
• Bind IoT data points to their building models, verify data accuracy and connectivity, and commission complete subsystems: energy metering, lighting, chiller/AHU controls and environmental monitoring, end to end
• Train and certify client and partner engineers — including property managers, hotel operators and shopping centre administrators — to configure, operate and maintain the platform independently after handover, through a mix of virtual, in-person and hands-on lab sessions
• Own recertification for every partner team you've trained, running annual refreshers to keep operational and data-quality standards consistent across sites
• Meet global quality benchmarks (data precision ≥95%, completeness ≥98%, IoT connectivity ≥95%, accuracy ≥98%) through rigorous self- and peer-review before client submission
• Collaborate daily with Project Managers, BIM Modellers and Solution Architects on delivery planning, model accuracy and platform configuration
• Diagnose and resolve field issues, including BIM-to-reality discrepancies, multi-protocol IoT integration problems and data-modelling edge cases, escalating complex cases to Tier-3 support

Requirements

MUST-HAVES

• Hands-on experience in building MEP design, construction, building digitalisation, BIM delivery, Building Management Systems, IoT deployment, or smart building technology
• Solid understanding of building MEP systems (HVAC, electrical, plumbing, fire protection, security, building automation/DDC), with the ability to read mechanical/electrical drawings and identify equipment on site
• Working proficiency with BIM tools (Revit) and CAD/IFC drawing interpretation
• Strong attention to detail and ability to maintain consistent data-quality standards across large data volumes
• Understanding of IoT communication protocols (BACnet, Modbus, MQTT, OPC UA) and practical experience with IoT deployment or device commissioning
• Strong collaboration and communication skills in cross-functional, multicultural project teams
• Professional fluency in English
• Right to work in the UK
• Diploma or Bachelor's degree in Engineering (Electrical, Mechanical, Building Services), Facilities Management, Information Technology, or a related field

NICE-TO-HAVES

• Experience designing or delivering technical training or certification programmes to external or non-technical audiences
• Coaching, presentation and training-delivery skills, comfortable teaching technical content clearly to partner audiences, including those who don't have English as a first language
• Working knowledge of UK building standards and CIBSE guidance (Part L, Part F, TM44)
• Wire-level IoT protocol debugging experience (BACnetScan, Modbus Master, UAExpert, MqttInsight or similar)
• Facility management or building operations experience
• Strong structured-data thinking: translating complex MEP hierarchies into clear, machine-readable classifications
• Prior field delivery experience on construction sites or in commissioning environments

Benefits

Why Join Janus Digital

Every building on the planet is running below its potential. You'll be one of the engineers closing that gap, building by building, as part of Janus Digital's first UK cohort. Compensation is competitive and performance-based, tied to delivery quality and outcomes. You'll get comprehensive training through Janus Digital's newly developed platform certification programme — helping shape it as part of the first cohort, ahead of its rollout to other regional offices — and hands-on experience across commercial offices, hotels, shopping centres and mixed-use developments. Your scope grows with you: as you take on more training and certification ownership for partner teams, your seniority and career path grow with it, from Delivery Engineer to Senior Engineer, with routes into regional lead or specialist roles, plus certification sponsorship for BIM, IoT and related credentials.
