mechanical design engineer role with room to grow technically
Responsum Global · London, England ·
Last confirmed by our partners on 6 Nov 2026.
You are a mechanical design engineer who wants to keep building technical depth, not get pulled into pure coordination work before you are ready for that trade off. This is a well established, nationally operating building services consultancy with decades of history, known for energy efficient mechanical design across HVAC, public health and controls.
The London base works across commercial offices, healthcare, education and residential projects, and is growing steadily as national client relationships bring more work into the capital. The usual frustration at this stage is being handed a narrow slice of a project rather than following the design through, especially once a firm gets large enough to specialise engineers into single project phases.
Here, growth is bringing more varied London work in rather than more layers, so a design engineer joining now gets breadth across sectors rather than being boxed into one. Working within a nationally established consultancy also means the standards, tools and back office support behind you are more developed than a smaller practice could offer, while the London team itself stays close enough that your work is still visible day to day rather than lost in a much bigger structure.
If you want technical variety without losing hands on design work, this is worth a conversation. Salary is between 42,000 and 52,000, depending on experience.
