Senior Mechanical Design Engineer, Mechanisms

About Mach Industries

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.

The Role

Mach Industries is seeking a Senior Mechanisms Engineer to design, analyze, prototype, and deliver mechanical mechanisms for next-generation aerospace and defense platforms.

In this hands-on role, you will own mechanism development from initial concept and kinematic architecture through detailed design, prototyping, testing, and production release. You will develop moving assemblies that meet demanding requirements for performance, reliability, mass, packaging, and environmental survivability while optimizing for manufacturability, assembly, cost, and production scalability.

You will work closely with mechanical, structures, avionics, controls, manufacturing, and test engineering teams to integrate mechanisms into larger vehicle systems. The ideal candidate combines strong mechanical fundamentals with practical experience designing, building, and troubleshooting complex moving hardware in a fast-paced development environment.

Key Responsibilities

• Own the mechanical design and development of mechanisms, from early CAD concepts to functional prototypes, drawing releases including GD&T, and eventually mass production.

• Design and analyze linkages, pivots, joints, bearings, shafts, gears, cams, latches, hinges, deployable assemblies and other mechanisms to meet program requirements.

• Define requirements for and select actuators, motors, and other drive systems to meet required profiles, torques, speeds, and positioning requirements.

• Drive manufacturability, part selection, and tolerance stack-up decisions (GD&T) for scalable production.

• Design fixtures and tooling to manufacture, assembly, inspect, qualify, and test mechanism assemblies

• Perform analytical modeling and simulation (kinematics and FEA) to evaluate mechanism system performance, guide design decisions, and inform trade studies.

• Work cross functionally to establish mechanism requirements, schedules, and interface control documents (ICDs)

• Ability to support critical development and test milestones, including occasional extended hours and weekends as needed

Required Qualifications

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

• 5+ years of experience in mechanical engineering, with a focus on designing and prototyping moving, mechanism systems

• Strong skills in 3D modeling with CAD tools (e.g., NX, SolidWorks, etc.) including expertise in drafting and GD&T per ASME Y14.5

• Strong understanding of mechanical design fundamentals, including kinematics, force and torque transmission, bearings and joints, fits and clearances, tolerance stack-ups, and structural load paths.

• Demonstrated experience taking mechanisms from concept through detailed design, prototyping, functional testing, and design iteration.

Preferred Qualifications

• Advanced degree (Master’s or PhD) in Mechanical Engineering, Aerospace Engineering, Mechatronics, Electrical Engineering, or a related field.

• Experience developing mechanisms for aerospace vehicles, UAVs, robotics, deployable systems, flight controls, or other mass- and volume-constrained applications.

• Experience analyzing mechanism kinematics, dynamic loads, friction, wear, fatigue, and tolerance sensitivity.

• Experience with mechanism reliability, life-cycle testing, environmental qualification, vibration, shock, and temperature extremes.

• Experience integrating mechanical mechanisms with electric, electromechanical, hydraulic, or pneumatic actuation systems.

• Experience designing for cross discipline impact including aerodynamics, fluid dynamics, or thermal management

• Experience with programming or scripting in Python, MATLAB, C++, or equivalent tools for engineering calculations, kinematic modeling, simulation, or test data analysis.

Additional Requirements

• Available to work extended hours and weekends as needed
