Our client, a leader in aerospace simulation, is seeking a Mechanical Design Engineer to join their advanced team in Southampton, PA.
 
They design and build high-fidelity aircrew cockpits and aerospace motion simulation systems — fully functional, multi-axis robotic platforms used in professional aerospace and defense training. These platforms are not static enclosures, they replicate real-world aircraft dynamics through complex, integrated mechanical systems. Think motion rigs on the scale of Mission: SPACE in EPCOT, or the astronaut centrifuge systems often depicted in films, where structural weldments, sheet metal, multi-axis drives, planetary gearboxes, pneumatic actuation, sensors, and electromechanical components all work together in assemblies exceeding 15,000 parts.
 
In this role, you'll design across multiple subsystems — developing motion mechanisms, specifying gearboxes and drives, optimizing structural frames for stiffness-to-weight performance, and breaking large assemblies into manufacturable subassemblies. You'll integrate commercial off-the-shelf components with custom-designed parts, collaborate closely with in-house fabrication teams, coordinate with vendors, and support prototyping and testing to ensure designs perform as intended.
 
If you're an engineer who enjoys dynamic machinery, robotics, and systems-level design — and who thrives on variety and technical challenge rather than repetitive product iteration — this role offers broad technical exposure and meaningful engineering ownership.
 
Key Responsibilities

• Design and develop large-scale mechanical assemblies for motion-enabled cockpits and aerospace simulation platforms
• Engineer multi-axis motion systems, including planetary gearboxes, DC/AC drives, couplings, and supporting structural frames
• Develop pneumatic actuation systems and integrate electro-mechanical components to achieve precise motion control
• Design structural weldments, sheet metal assemblies, and dynamic mechanisms for motion fidelity and structural integrity
• Break complex assemblies into manufacturable subassemblies, ensuring clarity for internal fabrication and vendor production
• Select, evaluate, and integrate commercial off-the-shelf (COTS) components alongside custom-designed mechanisms
• Conduct design analysis for weight optimization, load-bearing performance, and motion system dynamics
• Generate and maintain bills of materials (BOMs), technical drawings, and CAD documentation within collaborative Vault environments
• Collaborate closely with in-house fabrication teams, external vendors, and cross-functional engineering teams to resolve design, assembly, and manufacturability challenges
• Participate in design reviews, providing constructive technical feedback and iterative improvements
• Support prototyping, testing, and refinement of motion platforms and subsystems during build and assembly

Requirements

• 7+ years of mechanical design experience in complex, multi-subsystem environments
• Bachelor's degree in Mechanical Engineering, Mechatronics, Robotics, or related field
• Experience designing motion systems, robotics, and dynamic mechanisms
• Strong knowledge of pneumatic actuation, electro-mechanical drives, and gearboxes
• Proficiency in structural weldments and sheet metal design for dynamic loads
• Experience managing large assemblies and creating manufacturable subassemblies
• Skilled in integrating commercial off-the-shelf (COTS) components with custom designs
• Proficiency in Autodesk Inventor or other collaborative CAD tools
• Understanding of GD&T and manufacturing processes
• Comfortable collaborating with fabrication teams, vendors, and cross-functional engineers
