Mechanical Engineer (Mid-Career)

Mach Industries • Huntington Beach, CA

90d

About The Position

Mach Industries is seeking a Mechanical Engineer to join our team in designing, prototyping, and iterating on mechanical and electromechanical systems that support next-generation defense platforms. In this hands-on role, you’ll contribute to the development of innovative mechanical components, work closely with embedded systems engineers, and help deliver manufacturable hardware. As a Mechanical Engineer, you will play a key role in prototyping and refining mechanical systems, integrating embedded controls, and optimizing designs for performance and scalability. Collaborating with a multidisciplinary team, you’ll help shape the next wave of defense technologies, from concept to deployment.

Requirements

• 3+ years of experience in mechanical engineering, with a focus on designing and prototyping mechanical systems.
• Proficiency in embedded systems development for controlling hardware devices (e.g., actuators, sensors).
• Strong skills in 3D modeling and CAD tools (e.g., NX, SolidWorks, etc.) for mechanical design and iteration.
• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, Electrical Engineering, or a related field.
• Hands-on experience with prototyping, testing, and integrating mechanical and embedded systems.

Nice To Haves

• Experience with C/C++ programming for embedded system development.
• Familiarity with lightweight materials, composites, or additive manufacturing techniques.
• Knowledge of aerodynamics, fluid dynamics, or thermal management as applied to mechanical systems.
• Prior work on defense or aerospace projects, with an understanding of mission-critical design requirements.

Responsibilities

• Own the mechanical design and development of subsystem-level hardware, from early CAD concepts to functional prototypes.
• Integrate mechanical systems with sensors, actuators, and embedded control hardware.
• Lead hands-on testing, including design validation and hardware iteration based on performance feedback.
• Drive manufacturability, part selection, and tolerance stack-up decisions for scalable production.
• Apply mechanical fundamentals (thermal, structural, materials) to inform robust, lightweight designs.
• Collaborate with electrical, embedded, and controls teams to ensure tight integration of hardware and software.
• Contribute to test plans, technical documentation, and engineering reviews.

Benefits

• Health insurance
• Retirement plans
• Opportunities for professional development
