Hadrian - Manufacturing the Future

Hadrian is building autonomous factories to reindustrialize America. By combining AI, advanced software, robotics, and full-stack manufacturing, we help aerospace and defense companies build rockets, satellites, aircraft, ships, and other mission-critical systems up to 10x faster and at significantly lower cost.

Following our $1.37B Series D at a $7.87B valuation, Hadrian is rapidly expanding our manufacturing footprint, launching new capabilities across welding, casting, forging, electronics, additive manufacturing, and more, while scaling our Factory-as-a-Service platform to transform how critical products are built.

Backed by leading investors including JPMorgan Chase, Valor Equity Partners, Andreessen Horowitz, Founders Fund, 137 Ventures, Lux Capital, T. Rowe Price, and Morgan Stanley, we’re building the future of American manufacturing—and looking for exceptional people to help make it happen.

If you’re ready to take on the most challenging and rewarding work of your career while helping create American manufacturing jobs for generations to come, you’re exactly who we’re looking for.

The Role

We are seeking a Mechanical Design Engineer to support the development of custom industrial machinery, automation equipment, robotic tooling, and mechanical systems. This role owns mechanical design activities from concept through manufacturing, assembly, testing, and commissioning. The ideal candidate combines strong CAD expertise with hands-on knowledge of fabrication, manufacturing, and automated equipment, while collaborating across engineering and operations teams to deliver reliable, scalable solutions.

Responsibilities

Design mechanical systems, machine assemblies, fixtures, tooling, and robotic end-of-arm tooling (EOAT) using 3D CAD software.

Create manufacturing drawings, bills of materials, and engineering documentation while applying GD&T and design-for-manufacturing principles.

Support fabrication, machining, welding, assembly, prototype builds, and testing activities to ensure successful execution of designs.

Collaborate with manufacturing, controls, project management, suppliers, and technicians to develop and improve equipment and processes.

Support design reviews, troubleshooting, startup, commissioning, and continuous improvement efforts to optimize performance, reliability, and cost.

Requirements

Bachelor’s degree in Mechanical Engineering or a related engineering discipline.

2+ years of mechanical design experience in industrial, manufacturing, automation, or related environments.

Proficiency with SolidWorks or similar 3D parametric CAD software.

Understanding of machining, welding, fabrication, assembly processes, engineering drawings, and GD&T.

Strong problem-solving, organizational, and communication skills with the ability to work effectively in cross-functional teams.

Preferred Qualifications

Experience designing custom machinery, automation equipment, robotics, fixtures, tooling, or EOAT systems.

Experience with pneumatic, hydraulic, vacuum, motion control, or sensor-integrated mechanical systems.

Hands-on experience supporting prototype builds, equipment assembly, testing, and commissioning.

Familiarity with FEA, engineering analysis tools, or mechanical simulation methods.

Experience working in manufacturing, startup, or fast-paced engineering environments.

Compensation

For this role, the target salary range is $120,000 - $165,000 (actual range may vary based on experience).

This is the lowest to highest salary we reasonably and in good faith believe we would pay for this role at the time of this posting. We may ultimately pay more or less than the posted range, and the range may be modified in the future. An employee's pay position within the salary range will be based on several factors, including, but not limited to, relevant education, qualifications, certifications, experience, skills, geographic location, performance, and business or organizational needs.
