Job description

Mechanical Design Engineer | Rate: £38.00 – £40.00p/h (Outside IR35)

Sheffield Rotherham Derby Worksop Mansfield

Are you an experienced Mechanical Design Engineer with strong fundamentals in mechanics, stress analysis and detailed design? Do you enjoy taking ownership of sub‑assemblies, progressing designs from concept through to final detailing, and delivering practical engineering solutions within a fast‑moving project environment?

My client is a global engineering manufacturer supplying specialist process‑equipment solutions to customers across industrial sectors. Their systems operate in demanding environments where reliability, safety and mechanical integrity are essential.

This is a hands‑on mechanical design contract, joining at a stage where the main system design is already at a mature level, and the project is now entering finalisation, detailing and sub‑assembly completion. You’ll work closely with a small, focused engineering team, taking ownership of key mechanical sub‑assemblies and progressing them through to finished design.

You will be responsible for progressing the mechanical design of multiple sub‑assemblies, producing detailed drawings, performing quick engineering calculations and ensuring all bolt‑on assemblies integrate correctly with the main machine.

Your responsibilities:

• Progress mechanical sub‑assemblies through to completion.
• Produce detailed mechanical drawings and supporting documentation.
• Standardise bolt‑on assemblies to ensure correct fit and interface.
• Carry out hand calculations and basic stress assessments.
• Interpret existing designs quickly using strong visual and technical understanding.
• Attend design reviews and technical meetings.
• Work closely with the wider engineering team to resolve issues and progress the design.
• Ensure designs are practical, manufacturable and mechanically robust.

You should be able to:

• Get up to speed quickly with an existing design.
• Work independently and make sound engineering decisions.
• Confidently answer technical questions and justify design choices.
• Interpret drawings and technical information with minimal guidance.
• Progress detailed design work efficiently within agreed timescales.
• Understand aluminium, conveyor systems, foundry or similar environments.

Why Apply?

This is a chance to take ownership of meaningful mechanical design work within a high‑integrity engineering environment, contributing directly to sustainability and advanced industrial technology.

You’ll join a close‑knit engineering team, working directly with senior technical leadership, with clear deliverables and the autonomy to drive your own sub‑assemblies to completion.
