About The Position

We are seeking a Process Engineer – Micro-Machining to lead the design, operation, and optimization of all micro-machining processes within our fast-growing magnet manufacturing start-up. This role will oversee high-volume precision material slicing, component shaping, and finishing operations, ensuring tight dimensional tolerances, surface quality, and process stability. You’ll play a key role in developing and maintaining efficient, repeatable processes while supporting consistent product quality and reliable downstream operations in a dynamic, high-growth production environment.

Requirements

  • Bachelor’s degree in Mechanical Engineering, Chemical Engineering, Materials Science, or a related field (advanced degree preferred).
  • Experience in micro-machining, precision part manufacturing, or related processes.
  • Strong analytical and problem-solving skills, including data analysis and SPC.
  • Proficiency in operating and optimizing micro-machining equipment and processes, emphasis on diamond abrasive slicing and grinding for shaping.
  • Knowledge of dimensional tolerances, surface finish, and precision inspection.
  • Familiarity with SOPs, process documentation, FMEAs, and quality control.
  • Ability to collaborate effectively with cross-functional teams in a fast-paced start-up environment.

Nice To Haves

  • Experience with automation, part handling, and training operators or junior engineers is a plus.

Responsibilities

  • Own operation and design of micro machining equipment and processes.
  • Ensure small parts meet strict dimensional, surface finish, and edge preparation requirements.
  • Implement and maintain automation systems to maximize throughput and minimize handling.
  • Oversee pre-inspection cleaning, tumbling, slicing, grinding, and chamfering.
  • Maintain SOPs, process documentation, and FMEAs for micro machining.
  • Collaborate with maintenance for preventive maintenance and troubleshooting.
  • Monitor quality metrics and SPC data to ensure process control.
  • Participate in equipment procurement, FAT/SAT, and vendor evaluation.
  • Train operators and junior engineers in precision machining, inspection, and safety protocols.
  • Interface with downstream coating engineers to ensure parts are ready for plating.
