About The Company
Amca is building a new industrial base for America that is faster, distributed, and multi-sourced. We increase competition and capacity for every class of critical component to build and sustain the planes, military vehicles, and core infrastructure America needs. For decades, America’s legacy industrial base for critical components has become increasingly uncompetitive and capacity-constrained. As a result, the gap between what America needs and what it can produce is the largest it has been in generations. To address today’s bottlenecks, Amca is pioneering a faster and more resilient way to develop and manufacture critical aerospace and defense components. Traditional manufacturers often silo design, testing, and production into separate workflows, resulting in years-long timelines and high program risk. Amca brings those functions together into a single, integrated system that pairs rapid design and qualification of components with certified production at scale. By combining rapid prototyping, software-enabled testing, extensive qualification infrastructure, and a growing network of AS9100D-certified factories, Amca can move critical components from requirement to production within weeks. The end result is faster delivery, greater access to technical data, and reduced dependence on a single source of supply. Today, Amca supplies products for major aerospace and defense platforms, including the F-35, F-16, F/A-18, Mk-48, 737MAX, 787, 777, A320, and M1 Abrams. We also support U.S. military sustainment programs focused on readiness-related shortages and diminishing manufacturing sources. We have raised $376M in funding and are backed by leading investors including Caffeinated Capital, Lightspeed Venture Partners, Andreessen Horowitz, Lux Capital and Founders Fund.
About the Role

Amca is building America’s new industrial base. Since the 1990s, our ability to build new aviation and military systems and maintain the ones we already have has eroded. Today, the gap between what the nation needs to produce and what it is capable of producing is the largest it has been in generations.

To help close that gap, Amca rapidly develops and manufactures new critical components and subsystems required to build and sustain the planes, military vehicles, and core infrastructure America needs. Today, we operate seven factories nationwide, including our advanced prototyping and testing headquarters in El Segundo, and deliver avionics, hydraulic, and electrical components for platforms such as the F-35, F-16, F/A-18, 737MAX, 787, A320neo, A321, Mk-48, and M1 Abrams.

 

Overview

The Senior Magnetics Engineer leads the design of Amca's magnetic components and electromagnetic devices. You will design transformers, inductors, solenoids, motors, and magnetic actuators for power electronics and fluid control hardware, pairing magnetic and thermal analysis with manufacturable, high-reliability designs. This is a specialized design role for an engineer who lives at the intersection of electromagnetics, materials, and thermal performance.

Responsibilities

Magnetic Design and Analysis

  • Lead the design of transformers, inductors, solenoids, motors, and magnetic actuators.
  • Perform magnetic analysis and FEA to predict flux, force, inductance, and losses.
  • Model core loss, copper loss, saturation, and thermal behavior across the operating envelope.
  • Select magnetic materials, wire, insulation systems, and core geometries.

Documentation and Data Packages

  • Produce winding specifications, magnetic component drawings, and technical data packages.
  • Author design requirements and interface control documents for magnetic assemblies.
  • Maintain design records and support configuration management.

Integration and Cross-functional Support

  • Partner with electrical, mechanical, and test teams through build and qualification.
  • Lead root cause analysis and corrective action on magnetic design and field issues.
  • Review the work of junior engineers and mentor them on magnetics design methods.

Basic Qualifications

  • Bachelor's degree in electrical engineering, mechanical engineering, or a related technical discipline.
  • 5+ years designing magnetic components or electromagnetic devices in aerospace, defense, or a comparable high-reliability industry.
  • Strong command of electromagnetics, magnetic materials, and thermal fundamentals.
  • Experience with magnetic FEA tools such as ANSYS Maxwell or comparable software.
  • Demonstrated ability to carry a magnetic design from requirements through qualification.

Preferred Qualifications

  • Master's degree in a relevant engineering discipline.
  • Experience designing high-frequency magnetics for power conversion.
  • Experience with solenoid or magnetic actuator design for fluid control hardware.
  • Familiarity with DO-160 environmental qualification and relevant MIL-STD requirements.
  • Experience working across multiple manufacturing sites or factories.
