About the Job

Requirements

  • A bachelor's degree in Mechanical Engineering or a related field, or equivalent practical experience.
  • More than 15 years of experience in mechanical design, with a strong focus on fixture, jig, and tooling design.
  • Strong knowledge of manufacturing processes, including machining, sheet metal fabrication, welding, assembly, and precision mechanical components.
  • Strong understanding of design for manufacturability and practical engineering design.
  • Proficiency in computer-aided design software for 3D modeling and detailed drawing creation.
  • Ability to independently develop designs from concept to final release.
  • Strong problem-solving and troubleshooting skills.
  • Ability to communicate clearly and work with engineers, technicians, suppliers, and manufacturing teams.
  • Ability to balance technical requirements, cost, schedule, and manufacturability.

Responsibilities

  • Design and develop fixtures, jigs, tooling, and mechanical support equipment for manufacturing and engineering applications.
  • Create detailed 3D models, 2D drawings, bills of materials, and design documentation using computer-aided design tools.
  • Ensure designs meet requirements for functionality, manufacturability, cost, quality, safety, and reliability.
  • Apply design for manufacturability and design for assembly principles to optimize designs for machining, fabrication, assembly, and production use.
  • Work with manufacturing, process, test, quality, and engineering teams to understand needs and convert them into practical design solutions.
  • Select appropriate materials, tolerances, surface finishes, and standard components based on application and manufacturing methods.
  • Support prototype builds, design reviews, debugging, and design improvements based on shop floor feedback.
  • Coordinate with internal and external fabrication suppliers to ensure designs are producible and delivered on schedule.
  • Solve problems involving fixture performance, durability, ergonomics, and usability.
  • Manage multiple projects independently and complete tasks with little or no day-to-day oversight.
  • Provide technical guidance and share best practices with junior team members when needed.
  • Lead design activities from concept through implementation.
  • Identify risks early and propose practical solutions.
  • Communicate across functions and influence design direction through technical judgment.

Desired Qualifications

  • Experience designing tooling or fixtures for high-volume manufacturing, test processes, or automation environments.
  • Familiarity with tolerance stack-up, geometric dimensioning and tolerancing, and mechanical design standards.
  • Experience working directly with machine shops, suppliers, and contract manufacturers.
  • Knowledge of fixture validation, ergonomic considerations, and continuous improvement in production environments.
