December 2026 New Graduate Engineer, Mechanical

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.

Responsibilities

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

Requirements

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 December 2026 or January 2027

Nice to have

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.

Benefits

highly competitive equity grants; health insurance; retirement plans; opportunities for professional development
