Mechanical Design Engineer – Process Skid/Containeri...

Goal of the role

Own the end-to-end design process for Bluemethane's methane recovery and measurement systems, from concept through detailed design, fabrication oversight, and delivery. This includes skid-mounted systems, compliance with standards, and preparation of operating and maintenance documentation. Key outcomes

• Complete skid designs including structural frames, piping, and equipment layouts, optimised for manufacturability and transport.
• Accurate 3D models and drawings using Autodesk Inventor, including GA, isometrics, and P&IDs aligned with process requirements.
• Design compliance with applicable codes (ASME, BS, ISO) and Bluemethane's internal standards.
• Fabrication-ready packages: BOMs, drawings, and specifications delivered to suppliers.
• Quality assurance: Supervise skid manufacturing and assembly to ensure adherence to design and safety standards.
• Operating & Maintenance Manuals prepared for handover to clients.

• Traceable design reviews and documentation maintained throughout the project lifecycle.

• Responsibilities

• Concept to delivery: Translate process requirements into skid designs, manage design iterations, and oversee fabrication and assembly.
• 3D CAD modelling: Develop detailed assemblies and components in Autodesk Inventor; apply Tube & Pipe tools for complex piping systems.
• Drawing production: Generate fabrication drawings, P&IDs, and isometrics; maintain revision control.
• Standards application: Ensure designs meet ASME, BS, and ISO codes for pressure vessels, piping, and structural supports.
• Manufacturing oversight: Liaise with fabricators, monitor build quality, and resolve design queries during construction.
• Documentation: Prepare BOMs, datasheets, and comprehensive O&M manuals for delivered systems.
• Collaboration: Work with process, controls, and experimental engineers to integrate mechanical and electrical requirements.
• Continuous improvement: Incorporate lessons learned from pilot builds and client feedback.

Essential skills & experience

• 5+ years in mechanical/process design for skid-mounted systems or packaged equipment.
• Expert proficiency in Autodesk Inventor (mandatory); familiarity with AutoCAD Plant 3D and Design Review.
• Strong understanding of design standards and codes (ASME, BS, ISO) for piping and pressure systems.
• Experience producing P&IDs, GA drawings, and isometrics.
• Familiarity with manufacturing processes for skids and ability to supervise quality during fabrication.
• Ability to prepare Operating & Maintenance Manuals and manage documentation.
• Collaborative approach and clear communication skills.

Nice-to-have

• Knowledge of HAZOP considerations in design.
• Familiarity with process equipment for water/wastewater systems.
• Exposure to fabrication and assembly practices for modular systems.
• Familiarity with Finite Element Analysis (FEA) will be considered a plus.

Qualifications

• Degree in Mechanical/Process Engineering or equivalent experience.

Working Mode

• Based at Bluemethane's Cranfield office; hybrid work possible with on-site presence for design reviews, fabrication supervision, and pilot integration.
