December 2026 New Graduate Engineer, Mechanical

Founded in 2023, Mach Industries is a rapidly growing defense technology company focused on developing next-generation autonomous defense platforms. At the core of our mission is the commitment to delivering scalable, decentralized defense systems that enhance the strategic capabilities of the United States and its allies. With a workforce of approximately 350 employees, we operate with startup agility and ambition.

Our vision is to redefine the future of warfare through cutting-edge manufacturing, innovation at speed, and unwavering focus on national security. We are dedicated to solving the next generation of warfare with lethal systems that deter kinetic conflict and protect global security.

Mach Industries is seeking a New Grad 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 manufacturable hardware.

At Mach Industries, we are redefining the future of defense through advanced, scalable platforms. As a Mechanical Engineer, you will play a key role in prototyping and refining mechanical systems, 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.

• Own the mechanical design and development of subsystem-level hardware, from early CAD concepts to functional prototypes, all the way through mass production.

• 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.

• Contribute to test plans, technical documentation, and engineering reviews.

• Perform analytical modeling and simulation to evaluate mechanical system performance, guide design decisions, and inform trade studies.

• Ability to support critical project milestones, including working extended hours or weekends

• 1+ years of experience in mechanical engineering, with a focus on designing and prototyping mechanical systems (can be in a professional, hobby or academic setting)

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, Electrical Engineering, or a related field.

• Graduating with a bachelor’s degree, master’s degree or PhD by end of 2026 or January 2027

• Intermediate skills in 3D modeling and CAD tools (e.g., NX, SolidWorks, etc.) for mechanical design and iteration.

• Experience with programming languages (e.g. python, MATLAB, C++) for analytical modeling, simulation and engineering problem-solving.

• Familiarity with lightweight materials, composites, or additive manufacturing techniques.

• Experience with FEA or multi-physics software packages.

• Knowledge of aerodynamics, fluid dynamics, or thermal management as applied to mechanical systems.
