About the job

Requirements
  • A bachelor's or advanced degree in aerospace engineering, manufacturing engineering, materials engineering, mechanical engineering, or engineering physics.
  • At least 1 year of engineering experience in manufacturing, design, test, or development; internship and project team experience is applicable.
  • A strong understanding of engineering first principles, specifically thermodynamics, fluid dynamics, and solid mechanics.
Responsibilities
  • Develop build methodology from industry standards and conduct research and development to improve component manufacturing processes and enable new methods.
  • Oversee assembly and manufacturing procedures for new and existing hardware.
  • Own design-for-manufacturability changes to part drawings and make drawing changes as needed to eliminate repeat failures.
  • Conduct development campaigns for new manufacturing methods and write specifications on manufacturing best practices based on real-world data for design engineers to follow.
  • Evaluate purchasing commercial build and manufacturing capabilities off the shelf against designing and developing capabilities in-house.
  • Serve as the information source for design engineers on manufacturing methods, machine operation, and optimizing parts for different methods.
  • Develop and implement tooling to enable high-quality builds of company hardware.
  • Identify, plan, and execute capital equipment, machine, and layout upgrades to meet changing needs.
  • Partner with engineering and production teams to generate ideas, designs, and improvements for current and next-generation vehicles.
  • Assist design engineers in guiding new designs from concepts to qualified, production-capable aerospace components.
  • Prototype new components at the in-house research and development lab and participate closely in prototype development.
Desired Qualifications
  • At least 2 years of professional experience in aerospace or mechanical engineering.
  • At least 2 years of experience with geometric dimensioning and tolerancing concepts.
  • Experience building and testing fluid and/or electrical systems.
  • Experience building and testing pneumatic, hydraulic, and structural assemblies.
  • Experience with scientific computing languages such as Python or MATLAB.
  • Experience with Siemens NX or a similar computer-aided design package.
  • Experience with design-for-manufacturing improvement projects.

Simplify's Take

What believers are saying

  • May 20, 2026: Amca raised $300 million Series B at over $1 billion.
  • The round backed factory acquisitions nationwide and RAPID deployment across its network.
  • Amca's El Segundo prototyping hub and six U.S. factories support faster delivery now.

What critics are saying

  • Amca depends on integrating acquisitions like BC Systems, Cal-Draulics, Electrocube, and Payne Magnetics.
  • Aerospace quality failures or AS9100 gaps would instantly block Boeing and Lockheed orders.
  • Customer concentration and defense-program delays can crush demand and valuation within 2027.

What makes AMCA unique

  • Amca unifies engineering, qualification, and manufacturing through RAPID, cutting timelines 67%.
  • By May 2026, Amca operated seven factories and 123,000 square feet across three states.
  • Boeing, Lockheed Martin, Northrop Grumman, Airbus, and Raytheon already buy from Amca.
