Amidon Heavy Industries (Amidon) is a venture-backed company transforming America’s maritime capabilities. We specialize in autonomous underwater vehicles (AUVs) designed to address modern maritime challenges. By leveraging breakthroughs in manufacturing, energy systems, and autonomy, we deliver scalable solutions tailored for the evolving needs of naval operations.

For years, legacy companies have struggled to advance subsea technology, leaving critical gaps in innovation and capability. Amidon takes a fresh approach, breaking away from outdated practices to design affordable, high-performance systems that enhance naval security and fleet logistics.

We’re looking for a Junior Mechanical Engineer who’s excited to take ownership over the full lifecycle of a project—from idea to CAD to the machine shop to the ocean. This is a hands-on role, ideal for someone who loves building things, rapidly iterating, and solving real-world problems. You’ll work closely with a small, fast-moving team and get exposure to every part of the product development process.

What You'll Do

Assist in the design of AUV mechanical systems, including housings, propulsion systems, internal structures, and test fixtures
Fabricate and assemble prototypes using in-house tools and equipment (CNC, lathe, composites, etc.)
Test mechanical systems in the lab and in the field; analyze results and iterate on designs
Support integration of mechanical components with electronics and software
Help with sourcing parts, managing inventory, and improving shop workflows
Contribute to basic mechanical analysis, including stress checks and hydrostatics/hydrodynamics (a plus, not a must)
Collaborate with a small, interdisciplinary team that values speed, quality, and creativity

What We’re Looking For

Bachelor’s degree in Mechanical Engineering or a related field
Passion for hands-on engineering, prototyping, and making things work in the real world
Some experience with CAD (we use SolidWorks), 3D printing, machining, or fabrication tools (personal projects or internships count!)
Curious mindset and a willingness to learn quickly and figure things out
Comfortable in a fast-paced, ambiguous startup environment where responsibilities evolve quickly
Strong communicator who works well in teams and isn’t afraid to ask questions
Bonus: Exposure to mechanical analysis, FEA, hydrostatics, hydrodynamic calculations, or robotics

Compensation Range: $90K - $110K
