Mechanical Engineer Defense Jobs (NOW HIRING)

Kform is a next-generation defense manufacturer helping leading defense and dual-use startups turn advanced technology into producible hardware. We work across design, engineering, prototyping, manufacturing, quality, and production readiness to move critical products from concept to fielded reality.

We are recruiting mechanical engineers who want to build real systems, solve hard physical problems, and move fast enough to meet the timelines defense technology demands. The battlefield waits weeks, not years.

The right person for this role has strong mechanical engineering depth and enough curiosity, range, and practical ability to work across the rest of the product development stack. You may be strongest in mechanical design, product architecture, thermal management, ruggedization, enclosures, fixtures, mechanisms, or manufacturing, but you want to understand how the whole machine works.

At Kform, you will not be trapped in a narrow lane. You will design, prototype, test, troubleshoot, document, and improve real hardware. You will work with engineers, technicians, machinists, suppliers, quality teams, customers, and production teams. You will learn the full scope of product development because you will be close to the work from idea to prototype to production.

This is one of the few places where mechanical engineers get to build things that matter, learn fast, and help strengthen American industrial capacity for defense.

You will lead the mechanical design, prototyping, testing, and production readiness of complex hardware products for defense and dual-use customers.

  • Design rationale

  • Technical trade studies

• Collaborate with manufacturing, quality, supply chain, and program teams to improve designs for:

  • Manufacturability

  • Assembly

  • Inspection

  • Cost

  • Schedule

  • Reliability

• Work directly with machinists, fabricators, vendors, and production teams to close the loop between design intent and physical output.

• Mentor junior engineers by modeling technical rigor, practical problem-solving, strong documentation, and extreme ownership.

• Manage smaller engineering projects independently, driving them from ambiguous requirements to completed outcomes.

• Contribute to continuous improvement across Kform’s engineering and manufacturing systems.
