What is a Mechanical Engineer role?
Mechanical engineers design, analyse and improve mechanical parts and systems. They translate requirements into CAD models and manufacturing drawings, validate designs through calculations and testing, and support production and suppliers to ensure products are safe, manufacturable and meet performance targets. Work spans concept development, prototyping and ongoing product support.
Concept & Detailed Design
Turn requirements into CAD models, drawings and BOMs ready for manufacture.
Testing & Validation
Plan and execute prototype tests, record data and verify performance against specifications.
Manufacturing Support
Work with production and suppliers to resolve assembly issues and improve producibility.
Compliance & Safety
Ensure designs meet relevant standards, regulatory requirements and safety best practice.

Mechanical Engineer job description FAQs
Do I need chartered status to hire a Mechanical Engineer?
Chartered status (e.g. IMechE) is not mandatory for most mechanical engineering roles; it is a desirable marker of senior professional development. Reserve chartership as an essential requirement only where your role requires independent professional sign‑off or statutory responsibilities.
Should I include specific CAD packages in the advert?
Yes. Listing the primary CAD/analysis tools you use helps attract candidates with immediate productivity. If multiple tools are in use, indicate which are essential and which are beneficial.
How do I assess technical competence at application stage?
Ask for a short portfolio of CAD models or drawings, a summary of relevant projects and examples of calculations or test reports. Use a technical interview task or practical review to verify skills before final offers.
What level of manufacturing experience is typical?
Mechanical engineer candidates range from CAD‑focused designers to those with extensive shopfloor experience. Describe the role’s balance of hands‑on versus desk work so applicants can self‑assess fit.
Can I advertise hybrid or flexible working for this role?
Yes, but be explicit about any mandatory on‑site commitments for prototyping, testing or production support so candidates understand when presence is required.
