Job Details
Contract Mechanical Design Engineer – Solid Edge
Contract Mechanical Design Advanced Engineering Solid Edge
We are currently seeking an experienced Contract Mechanical Design Engineer to join a specialist engineering team working on complex, high–performance systems within the advanced energy and technology sector.
This is an excellent opportunity for a hands–on mechanical designer with strong Solid Edge experience to contribute to technically challenging projects involving complex mechanical assemblies, cryogenic systems, superconducting technologies, test equipment and associated engineering infrastructure.
The Role
As a Contract Mechanical Design Engineer, you will be responsible for developing mechanical components and assemblies from concept through to manufacture, working closely with engineers, technical specialists, manufacturing teams and suppliers.
You will use Solid Edge as a key design tool, producing accurate 3D models and detailed engineering drawings that communicate design intent, manufacturing requirements and operational information.
Key Responsibilities
- Create and develop 3D mechanical models and engineering drawings using Solid Edge.
- Produce detailed drawings suitable for manufacture, assembly and inspection.
- Develop mechanical components and complex assemblies from initial concept through to delivery.
- Lead or contribute to mechanical design activities across engineering projects and programmes.
- Work with engineering stakeholders and subject matter experts to define requirements and develop practical design solutions.
- Carry out engineering calculations, design verification and analysis, including FEA where appropriate.
- Work closely with manufacturing teams, technicians and suppliers to resolve technical issues and optimise designs.
- Select appropriate materials and manufacturing processes, including advanced and emerging technologies.
- Participate in design reviews and ensure actions are followed through to completion.
- Produce technical documentation, calculations, reports and engineering procedures.
- Ensure safety, reliability, manufacturability and maintainability are considered throughout the design process.
- Work within appropriate engineering standards, regulations and design codes.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
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.

Essential: Solid Edge Experience
Strong, demonstrable experience using Solid Edge is essential for this position.
The successful candidate will be confident using Solid Edge for:
- 3D part modelling
- Complex assembly design
- Engineering drawings
- Design modifications and configuration control
- Creation of manufacturing–ready documentation
- Managing complex mechanical design data
- Communicating design intent through detailed CAD models and drawings
Experience working within a PLM, PDM or controlled engineering data environment would be highly advantageous.
About You
We are looking for a Mechanical Design Engineer who combines strong CAD capability with sound practical engineering judgement.
You Should Have
- HNC/HND or degree–level qualification in Mechanical Engineering, or equivalent relevant experience.
- Strong professional experience using Solid Edge in a mechanical engineering/design environment.
- Experience designing complex mechanical components and assemblies.
- Strong understanding of mechanical engineering principles, materials and manufacturing processes.
- Experience producing detailed engineering drawings to a high standard.
- Experience with engineering calculations and analysis/FEA software.
- Experience working on complex engineering projects where problem–solving and attention to detail are critical.
- Excellent communication skills and the ability to work effectively with engineers, technicians, suppliers and other stakeholders.
- The ability to work independently while also contributing effectively within a multidisciplinary team.
- A structured approach to design, documentation, configuration control and revision management.
- Awareness of relevant engineering standards, regulations and safety requirements.


Get help with your application
Your very own career expert that helps elevate your application to the next level.
Knowledge of electromagnetic principles and their mechanical implications in high–current or superconducting systems would be beneficial, as would experience with cryogenic, vacuum, pressure or other highly engineered systems.
Working Environment
The role will support technically demanding engineering programmes involving areas such as:
- Fusion and advanced energy technology
- High–temperature superconducting magnet systems
- High–current mechanical systems
- Cryogenic equipment
- Vacuum systems
- Complex mechanical assemblies
- Advanced manufacturing
- Engineering test rigs and facilities
The role includes significant interaction with engineering, manufacturing and testing teams, so a practical, hands–on approach to mechanical design is highly valued.
Rullion celebrates and supports diversity and is committed to ensuring equal opportunities for both employees and applicants.
