Mechanical Design Engineer

Job Description

Role Purpose

Own the end-to-end design process for OSCABE’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 OSCABE’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.



Requirements

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.

Experience:

  • Autodesk Inventor: 1 year (required)

  • Piping systems and standards: 1 year (required)

  • Pressure vessels: 1 year (preferred)

  • Vacuum systems: 1 year (preferred)

Work Authorisation:

  • United Kingdom (preferred)



Benefits

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

Job Type: Full-time
Pay: £42,000.00–£48,000.00 per year

Ability to Commute/Relocate:

  • Cranfield MK43: reliably commute or plan to relocate before starting work (preferred)
