Competitive Salary + Bonus + Growth Opportunity

The experience expected from applicants, as well as additional skills and qualifications needed for this job are listed below.

A fast-growth engineering consultancy delivering complex infrastructure systems across the UK is looking for a talented BMS Engineer to join its expanding London team.

This business is already making serious waves within rail and infrastructure, delivering rebuilds, upgrades and extensions from a communications and systems integration perspective. Backed by an inspirational leadership team with a proven track record of scaling businesses successfully, the company has grown rapidly and shows no signs of slowing down.

With a growing project portfolio including major rail frameworks and high-profile infrastructure programmes, this is an opportunity to join a business early in its growth journey and genuinely shape its future.

The Role

This position sits at the intersection of mechanical systems, building management systems and systems engineering.

You’ll focus on the integration of Siemens BMS technologies, ensuring critical mechanical assets can communicate effectively within wider building and infrastructure systems.

This is not a controls algorithm programming role — it’s about understanding system interfaces, protocols and integration requirements early in the design lifecycle.

You’ll be involved in:

• Designing and integrating BMS-connected mechanical systems
• Working with HVAC systems, AHUs, chillers, heat pumps and cooling systems
• Reviewing supplier equipment compatibility with communication protocols such as BACnet and Modbus
• Identifying integration risks early and proposing technical solutions
• Supporting the development of cohesive smart building and energy management systems
• Working closely with mechanical, electrical and project delivery teams across major infrastructure projects

Ideal Background

We’re looking for engineers with experience across:

• BMS / BEMS design and systems integration
• Siemens Desigo or similar BMS platforms
• HVAC and mechanical building systems
• BACnet, Modbus, OPC UA and building automation protocols
• Smart buildings and connected infrastructure
• AutoCAD, Revit, EPLAN or MicroStation
• Energy management and building performance optimisation
• Technical coordination across multidisciplinary teams

Experience within rail, infrastructure, transport or large-scale building projects would be highly beneficial.

Why Join?

• Flexible and hybrid working
• Rapidly growing consultancy with genuine career progression
• Opportunity to influence business growth and technical direction
• Exciting rail and infrastructure project portfolio
• Collaborative and highly entrepreneurial culture
• Strong leadership with a proven history of scaling successful engineering businesses
