December 2026 New Graduate Engineer, Mechanical

About the role

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. You will play a key role in prototyping and refining mechanical systems, optimizing designs for performance and scalability, and collaborating with a multidisciplinary team to shape the next wave of defense technologies, from concept to deployment.

Responsibilities

• Own the mechanical design and development of subsystem-level hardware, from early CAD concepts to functional prototypes, 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.
• Support critical project milestones, including working extended hours or weekends as needed.

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 in 2026 or 2027.

Skills

• Intermediate skills in 3D modeling and CAD tools (e.g., NX, SolidWorks) 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 included in most offers as part of total compensation.
• Health insurance and retirement plans.
• Opportunities for professional development.

Pay

The salary range for this role is an estimate based on a wide range of compensation factors, inclusive of base salary only. Actual salary offers may vary based on work experience, education, training, critical skills, and business considerations.
