Greenjets Limited; Wolverton; On-site; GBP 45,000 - 65,000; Full time

Job summary

Greenjets Limited in the UK is seeking a Mechanical Design Engineer to turn engine concepts into precise, buildable hardware. You’ll own detailed designs of rotating assemblies, shafts, bearings and housings for high‑speed propulsion systems.

Collaborating with propulsion engineers, manufacturing and test teams, you’ll move from CAD through manufacture and testing, applying GD&T, material selection and tolerance analysis to ensure robust, repeatable production.

Qualifications

• Bachelor's or equivalent in Mechanical Engineering or related field.
• Strong experience in detailed mechanical design using 3D CAD.
• Proficient with GD&T, tolerance stack-ups and manufacturing drawings.
• Experience designing precision machined metallic components with tight tolerances.
• Ability to translate engineering requirements into manufacturable hardware.

Responsibilities

• Develop detailed mechanical designs for engine components, rotating assemblies and supporting hardware.
• Design precision machined metallic parts, including shafts, bearing housings, casings and bladed rotating components.
• Produce high-quality 3D CAD models, manufacturing drawings and GD&T with clear datum strategies and tolerance stack-up analysis.
• Define fits, clearances and interfaces accounting for manufacturing variation and thermal expansion.
• Select materials, finishes and treatments for operating temperatures, fatigue and wear.
• Design for manufacture and assembly with suppliers to balance performance, cost and repeatability.
