• Demonstrable ability to produce high-quality technical documentation.
  

• 
  
• Bachelor’s degree or higher in Mechanical Engineering or an equivalent engineering qualification.
  

• 
  
• At least five years of experience in mechanical design engineering within the defence or related engineering sector.
  
• Experience working on complex, safety-critical systems.
  
• Proven track record of delivering mechanical designs through full product lifecycle stages.
  

• 
  
• Excellent knowledge of mechanical design methodologies and best practises.
  
• Proficient in CAD modelling and engineering analysis techniques.
  
• Strong problem-solving skills with the ability to work independently and as part of a team.
  
• Effective communication skills, able to present technical information clearly to diverse audiences.
  
• Attention to detail and commitment to quality assurance.
  
• Ability to manage multiple priorities and meet demanding deadlines.
  
• Familiarity with relevant British and international engineering standards.
  

• 
  
• Membership of a recognised professional engineering institution such as the Institution of Mechanical Engineers.
  
• Experience with defence-specific design tools and simulation software.
  
• Security clearance or eligibility to obtain security clearance for work within the defence sector.
  

• 
  
• The role is primarily hybrid office-based (3 days) with occasional visits to manufacturing or testing facilities.
  
• Standard full-time hours are expected, with some flexibility required to meet project deadlines.
  
• The position may involve working within a secure environment requiring adherence to confidentiality and security protocols.
  
• Travel within the United Kingdom may be necessary to support project activities or client meetings.
