Standard Job Description

Designs major components, or major portions of a functional system, or technically advanced protoype, promotional or specific products. Develop or improve products and facilitate manufacturing operations. Develops basic data and makes preliminary layouts, sketches, and notes necessary to present design proposal. Investigates pertinent design factors such as ease of manufacture, availability of materials and equipment, interchangeability, replace ability, strength-weight efficiency, and contractual specification requirements and cost. Coordinates with other organizations affected by design development. Makes layouts of assemblies and details parts of devices, mechanisms, structures, and products. Checks completed layouts and drawings for clarity, completeness, conformity to standards, procedures, specifications, and accuracy of calculations and dimensioning. Identifies design errors, omissions, and other deficiencies, and recommends revisions and/or improvements in design layout to responsible engineers or designers.

About the role

The Mechanical Design Engineer will be responsible for carrying out the duties of the Engineering department, including design, prototyping, design proving, engineering documentation, and supporting calculations.

A key requirement of this role is the ability to obtain and maintain a high‑level security clearance. If you do not currently hold the required clearance, we can support you through the application process. DV Clearance will be required for the role - applicants should either already hold a DV or being prepared to go through an application immediately.

This position will require an on-site presence in Ampthill, Bedfordshire.

The role demands a high level of innovative thinking and the ability to synthesise ideas into functioning and manufacturable products that are compliant to design specifications and applicable legislation.  Working within a team of engineers and Design Authorities to design and develop high integrity components, complex mechanisms and linkages that will function and be durable in challenging environments.

Responsibilities and Duties

  • Use requirements specifications and a design brief to develop innovative yet robust design solutions that are compliant and fit for purpose.
  • Use CREO Parametric CAD to produce both concept and detail designs.
  • Produce supporting calculations and analysis to justify design decisions.
  • Work with SMEs, Users and  Design Authorities to develop concept design solutions.
  • Work with a team of Design Engineers with agreed interfaces to develop a single sub-system design solution.
  • Work with CAD engineers to enable the production of drawings and design data pack.
