Mechanical Engineer DFMA

Department: Design

Employment Type: Permanent - Full Time

Location: Alternative Heat Head Office

Reporting To: Head of Engineering DFMA

We are a leading engineering and construction partner specialising in the design, manufacture and delivery of high-performance offsite modular MEP solutions. Our expertise spans mission-critical infrastructure, renewable energy and decarbonisation projects, supporting clients across the UK and Europe.

By combining innovative engineering, digital design and advanced offsite manufacturing, we deliver high-quality solutions that accelerate project delivery, improve efficiency, and provide greater certainty for our clients. We build long-term partnerships through technical excellence, collaboration, and a shared commitment to delivering resilient, sustainable infrastructure for the future.

The role is responsible for delivering engineering outputs within the DFMA Engineering function, developing plant rooms, MEP skids and pipework systems that are manufacturable, modular and ready for assembly. The successful candidate will take ownership of models, drawings and Bills of Materials (BOMs) with minimal supervision, applying DFMA principles to improve buildability, efficiency and cost-effectiveness. They will also support the Lead Mechanical Engineer - DFMA with technical delivery, coordination and the maintenance of engineering standards.

• Produce and manage Solid Works models, fabrication drawings and assembly packs, pipe spool drawings, and BOMs for assigned work packages
• Develop skid layouts, plantroom configurations, pipework arrangements, spool strategies, and modular breakdowns
• Produce technical submittal content and maintain revisions through 4P
• Check and correct own outputs before issue; minimise rework into manufacturing and site

• Apply DFMA principles in all design and modelling activities
• Develop parametric and reusable Solid Works models to support efficient and consistent design
• Carry out fabrication detailing, assembly definition, and engineering checks/calculations as required
• Support engineering validation, including FEA where required (under guidance where needed), verification of supports, frames, and lifting arrangements

• Support integration of Solid Works outputs with BIM platforms (Revit/Navisworks/IFC)
• Produce coordination-ready exports and ensure outputs are usable in the coordination environment
• Identify and propose improvements to data exchange workflows, export consistency, and interoperability

• Deliver fabrication-ready information for manufacture: drawings, assembly packs, BOMs
• Design with manufacturability, access, lifting, transport, and build sequencing in mind
• Apply a cost and material efficiency mindset: reduce waste, standardise components/lengths, and simplify fabrication
• Use appropriate Solid Works features such as weldments, routing, piping, and cut lists This hard copy is uncontrolled. Printed for reference only.

• Use Solid Works PDM in line with defined workflows and standards
• Ensure correct structure, version control, and release discipline (no uncontrolled files)

• Comply with project requirements, client specifications, and internal DFMA standards
• Resolve day-to-day engineering and assembly issues; escalation complex issues with options and impacts
• Contribute to templates, standard libraries, and continuous improvement of modelling and fabrication workflows

• Strong working capability in Solid Works (modelling, assemblies, fabrication drawings, BOMs)
• Solid understanding of DFMA principles, fabrication methods, and modular assembly
• Working knowledge of Solid Works PDM and revision/release control.
• Understanding of BIM coordination principles and Solid Works BIM interoperability
• Ability to produce accurate, buildable engineering outputs independently and solve practical problems
• Strong attention to detail, and clear communication across Design/BIM/Manufacturing/Site
