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.

Senior Mechanical Engineer

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.

Application

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.
