About The Position

Mach Industries is seeking a Build Engineer to transform new product designs into physical builds. Working closely with Product Engineering and Manufacturing, this hands-on role will build first articles, enable rapid design iteration, and capture lessons that help products mature into production. The engineer will help prove design concepts through initial manufacturing, bridging design and manufacturing to support manufacturability, cost-efficiency, and mission-critical reliability. The role requires resourcefulness, speed, and technical rigor, with daily work alongside technicians on the production floor.

Requirements

  • Bachelor’s degree in mechanical, aerospace, or manufacturing engineering, or equivalent experience.
  • At least 1 year in production manufacturing, process engineering, or industrialization; internship and school project experience qualifies.
  • Strong troubleshooting, problem-solving, and communication skills.

  • Willingness to work on the floor daily alongside technicians.
  • Availability to work extended hours and weekends as needed.

Nice To Haves

  • Experience in aerospace, defense, automotive, or other high-rate production environments.
  • Ability to work autonomously in ambiguous situations with minimal documentation.
  • A “get it built” mindset and bias for speed.

Responsibilities

  • Act as the engineering owner for prototype builds across multiple products.
  • Translate design intent into practical build steps, processes, and checklists for technicians.
  • Debug and resolve design and manufacturability issues directly with design engineers.
  • Participate in design reviews to ensure design concepts are manufacturable.
  • Capture lessons learned and feed them back into the design and production system.
  • Source and coordinate quick-turn parts and prototype tooling.
  • Partner with technicians to train, enforce standard work, and improve safety and ergonomics.

Benefits

  • Healthcare, dental, and vision plans.
  • Retirement savings plans.
