Principal Mechanical Design Engineer

We are seeking an experienced Principal Mechanical Engineer to join a high-performing engineering team developing advanced electromechanical products for the automotive sector. This is a senior technical position responsible for leading complex mechanical design activities throughout the product development lifecycle.

The successful candidate will be an experienced and self-motivated engineer capable of independently solving challenging engineering problems while collaborating with multidisciplinary teams including systems, electronics, software, manufacturing, quality, and programme management. This role also provides technical leadership and mentoring to other engineers, promoting engineering excellence and best practice.

• Lead the mechanical design and development of complex automotive components and assemblies from concept through production.
• Create robust 3D CAD models and manufacturing drawings using Solid Works, applying advanced GD&T principles.
• Perform engineering calculations including:
  • Tolerance stack analysis
  • Press and interference fit calculations
  • Thermal expansion (CTE) assessments
  • O-ring and sealing calculations
  • Basic stress and structural approximations
• Conduct finite element analysis (FEA) using Solid Works Simulation and/or Ansys to validate designs against functional load cases.
• Support Design for Manufacturing (DFM) reviews with suppliers and manufacturing teams.
• Participate in Design Failure Mode and Effects Analysis (DFMEA) activities.
• Support structured problem-solving activities using 8D or equivalent methodologies.
• Present design concepts, technical analyses, and engineering recommendations to internal stakeholders, suppliers, and customers.
• Collaborate effectively within cross-functional engineering teams while maintaining ownership of individual work streams.
• Mentor junior engineers and contribute to continuous improvement of engineering standards, processes, and best practices.
• Manage assigned engineering activities, ensuring projects are delivered on schedule and to the required quality standards.

• Bachelor’s Degree in Mechanical Engineering or a related engineering discipline.
• Minimum of 8 years’ experience in mechanical product development within the automotive or comparable engineering sector.
• Strong proficiency with Solid Works CAD.
• Excellent understanding and application of Geometric Dimensioning and Tolerancing (GD&T).
• Experience using structural simulation software such as Solid Works Simulation or Ansys.
• Ability to perform detailed engineering calculations supporting mechanical design decisions.
• Experience conducting DFMEA.
• Knowledge of structured root cause analysis methodologies such as 8D.
• Demonstrated project planning and workload management skills.
• Strong communication and stakeholder management skills, including customer and supplier interaction.
• Ability to work independently while contributing effectively within multidisciplinary teams.
• Knowledge of hydraulic and electromechanical system design.
• Familiarity with Design Verification Plan and Report (DVP&R) processes.
• Advanced experience using Ansys Mechanical.
• MATLAB or scripting experience for engineering calculations and automation.
• Master’s Degree in Mechanical Engineering or a related discipline.
• Practical hands-on engineering experience gained through laboratory, workshop, or prototype development activities.

The ideal candidate is an experienced mechanical engineer who combines strong technical capability with practical problem-solving skills and a collaborative approach. They will be comfortable taking ownership of challenging engineering problems, influencing design decisions, mentoring colleagues, and delivering high-quality engineering solutions within a fast-paced product development environment.
