Senior BMS Controls Engineer

We are seeking a highly capable Senior Service & Small Works BMS Engineer to play a key role in the continued growth of our business. This is not a routine maintenance role — it is an opportunity to take ownership of technically interesting systems, build trusted client relationships, work on projects and directly influence the delivery of service and project work across a growing regional portfolio.

The role combines advanced service engineering with responsibility for identifying, pricing, and delivering improvement works. You will operate with a high degree of autonomy, acting as the technical face of the business on site while being fully supported by an experienced operations team.

In addition to maintaining and optimising existing systems, you will own small works opportunities from concept through to completion — developing recommendations, preparing quotations, and delivering solutions that improve system performance, reliability, and energy efficiency. This ownership provides valuable exposure to commercial, sales, and project management disciplines and offers a clear pathway into larger project delivery or technical roles.

This position covers the London region with travel in Central London and the surrounding areas. Participation in a 24/7 on‑call rota is necessary to support critical environments.

We are a growing organisation with ambitious plans, and this role is ideal for an engineer who wants to progress, broaden their skills, and be recognised for their contribution rather than remain in a purely reactive service position.

The role reports to the Regional Service Manager.
