Senior Mechanical Engineer

Senior Mechanical Engineer

Location: UK (with site visits as required)

Salary: £35,000 to £52,000

Are you a mechanical engineer who thrives on variety, hands-on design, and complex assemblies? At Ranheat Engineering, we’re a forward-looking SME specialising in industrial biomass boilers, conveyor systems and sheet-metal fabrication. We believe our 3D-scan + 3D-model approach gives us a world-leading edge in our sector.

We’re looking for a Senior Mechanical Engineer to join our design team. In this hybrid role you’ll:

• Design sheet-metal fabrications, boilers, combustion chambers, conveyor systems and silos.
• Adapt our existing 3D CAD assemblies for individual client layouts – including on-site surveying and modification.
• Use your mechanical engineering background and sound understanding of thermodynamics to optimise performance (particularly for biomass boilers/dust extraction systems).
• Work in Autodesk Inventor (primary) and AutoCAD (legacy drawings) to create detailed models and drawings for manufacture.
• Collaborate with manufacturing and installation teams to ensure accurate delivery, ease of install and full system integration.
• Occasionally visit client sites for surveys, commissioning and system adaptations.
• Ideally contribute to automation / industrial control panel design (not essential, but a plus).
• Join a dynamic SME environment where your role remains varied, impactful and visible across the business.

What we’re looking for:

• A degree (or master’s) in Mechanical Engineering (or equivalent).
• At least 2 years’ relevant experience in mechanical design (sheet-metal design/fabrication a strong advantage).
• Good working knowledge of thermodynamics and mechanical system performance.
• Proven CAD skills – preferably Autodesk Inventor and AutoCAD.
• Must be comfortable working in a mixed role: product-development (refining our standard designs) and project-based (customising for each client).
• Willingness to go on-site for surveys and commissioning.
• Interest in industrial automation and control systems (we’ll train the specifics).
• A self-starter mindset, ready to work in a smaller company environment where roles overlap and flexibility is key.

Why join Ranheat?

• You’ll work in an industry-leading niche: converting wood waste into energy, designing for real sustainability.
• A varied role – one day you’re refining a boiler design, next you’re adapting a conveyor layout and liaising with a client.
• A collaborative, motivated team where each person’s work is visible and valued.
• Opportunity to grow your skills – fabrication, site visits, 3D-scan modelling, system commissioning.
• The chance to make a real difference in a growing engineering business rather than being a small cog in a large corporation.

If you’re ready to step into a senior role where you can genuinely contribute, work across the design/manufacture/install chain, and enjoy the variety and challenge of an SME environment, we’d love to hear from you. Please send your CV and a short covering note explaining your experience with sheet-metal design, thermodynamics applications, CAD (Inventor/AutoCAD) and any automation/industrial control exposure.
