Senior CAD Engineer – Autodesk Inventor / AutoCAD – Skid & Containerised Systems
Senior CAD & Mechanical Design Engineer
About Bluemethane
Bluemethane’s mission is to prevent a billion tonnes of methane emissions from water. Our technology measures and captures dissolved methane, turning a harmful greenhouse gas into a clean energy opportunity.
Role Purpose
Own the end-to-end CAD and mechanical design process for Bluemethane’s skid-mounted and containerised methane recovery and measurement systems, from concept through detailed design, fabrication support, assembly, testing, and delivery. This is a hands-on senior CAD engineering role requiring:
- Advanced Autodesk Inventor and AutoCAD capability
- Practical experience with fabricated process equipment
- Clear, proactive communication with internal engineers, fabricators, suppliers, and stakeholders
The successful candidate must independently produce production-ready 3D models, assemblies, drawings, BOMs, and revision-controlled design packages for real fabricated equipment, not just perform basic drafting tasks.
Key Responsibilities
- Complete skid designs including structural frames, piping, and equipment layouts, optimised for manufacturability and transport.
- Produce accurate 3D models, assemblies, drawings, layouts, isometrics, and P&IDs using Autodesk Inventor and AutoCAD, aligned with process, fabrication, and installation requirements.
- Ensure code compliance with ASME, BS, and ISO standards, as well as Bluemethane’s internal design protocols.
- Deliver fabrication-ready packages, including BOMs, drawings, and specifications to suppliers.
- Supervise skid manufacturing and assembly, ensuring adherence to design and safety standards.
- Prepare Operating & Maintenance Manuals for handover to clients.
- Maintain clear design communication, including documented assumptions, decisions, risks, open issues, technical queries, and revision explanations.
- Conduct traceable design reviews and maintain revision-controlled documentation throughout the project lifecycle.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Key Responsibilities (Expanded)
- Concept to delivery: Translate process requirements into skid designs, manage iterations, and oversee fabrication and assembly.
- 3D CAD modelling: Develop detailed assemblies and components in Autodesk Inventor, using Tube & Pipe tools for complex piping systems.
- Drawing production: Generate fabrication-ready drawings, general arrangements, layouts, P&IDs, isometrics, BOMs, and revision-controlled documentation.
- 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.
- Communication: Provide clear, explicit, and proactive updates on:
- Design progress
- Risks and blockers
- Assumptions and changes
- Open actions
- 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.
- Proficient in Autodesk Inventor (advanced):
- Complex 3D assemblies
- Detailed part modelling
- Fabrication drawings
- BOMs and revision-controlled packages
- Proficient in AutoCAD:
- AutoCAD Plant 3D experience (desirable for layouts, P&IDs, piping documentation).
- Strong understanding of ASME, BS, and ISO design codes for piping and pressure systems.
- Experience producing P&IDs, general arrangements (GA) drawings, and isometrics.
- Familiarity with fabrication processes for skids and ability to supervise quality during assembly.
- Ability to prepare Operating & Maintenance Manuals and manage technical documentation.
- Excellent written and verbal communication, with a proactive and explicit reporting style.
- Can clearly document design assumptions, risks, changes, and supplier/fabricator clarifications early.
Get help with your application
Your very own career expert that helps elevate your application to the next level.
Note: Candidates with experience limited to basic 2D drafting, junior CAD support, or product design without fabrication ownership are unlikely to be suitable for this role.
Nice-to-Have
- Knowledge of HAZOP considerations in design.
- Familiarity with process equipment for water/wastewater systems.
- Experience with fabrication and assembly practices for modular systems.
- Exposure to Finite Element Analysis (FEA).
Qualifications
- Degree in Mechanical/Process Engineering or equivalent experience.
Working Mode
- Based at Bluemethane’s Cranfield office.
- Hybrid remote work possible, though on-site presence is required for:
- Design reviews
- Fabrication supervision
- Pilot integration
Application Guidance
Your CV must clearly demonstrate:
- Years of professional experience with Autodesk Inventor and AutoCAD.
- Examples of skid-mounted, modular, containerised, piping, or fabricated equipment projects.
- Types of drawings and documentation (BOMs, P&IDs, isometrics, GA drawings) you have personally produced.
- Role in taking designs from concept to fabrication, assembly, testing, or commissioning.
- Direct experience working with fabricators, suppliers, or multidisciplinary teams, including:
- Handling technical queries
- Managing design changes
- Documenting open actions and project communication.
