Mechanical Engineers
with expertise in Mechanisms at Barrios Technology. Working alongside our commercial spaceflight partners, our team is positioned to contribute to the future of space exploration. The successful candidate will have the opportunity to play in a role in various commercial space endeavors with our partners that include NASA, Intuitive Machines, Axiom Space, Lockheed Martin, and others.

The Mechanical Engineer (Mechanisms) will:

• Lead the design, development, integration, and verification of mechanisms for spacecraft, mobility systems, payloads, and other spaceflight applications.
• Serve as Product Design Lead (PDL) for assigned mechanism hardware, owning requirements, design maturation, procurement, integration, testing, and delivery.
• Serve as technical lead for mechanism design activities including bearing selection and analysis, geartrain development, lubrication systems, seal systems, and actuator integration.
• Develop performance requirements and specifications for stepper motors, brushless DC motors, controllers, and other motion-control hardware; support supplier selection, procurement, testing, and characterization activities.
• Generate and maintain 3D CAD models, engineering drawings, bills of materials, and associated technical documentation using configuration-controlled engineering processes.
• Perform engineering analyses including bearing and gear calculations, force and torque margin assessments, tolerance analyses, lubricant life evaluations, optimization studies, interference checks, and dynamic simulations.
• Develop and maintain mechanism bills of materials, support hardware procurement activities, and coordinate with suppliers, manufacturers, and internal stakeholders to deliver flight hardware.
• Develop test plans, procedures, support equipment, and data acquisition systems; execute functional, vibration, thermal-vacuum, environmental, deployment, and life-cycle testing of mechanism hardware.
• Identify technical risks, perform trade studies, develop prototypes, troubleshoot hardware issues, and implement mitigation strategies to close design and performance gaps.
• Lead requirements development, subsystem design reviews, verification planning, and customer presentations; interface with systems, structures, thermal, avionics, software, manufacturing, and test organizations and provide technical mentorship to junior engineers.

Skills:

• BS degree in Mechanical Engineering or related engineering discipline from an accredited institution, plus ten (10) years of related engineering experience.
• Experience leading the design, development, integration, and testing of mechanisms or electromechanical assemblies through the complete hardware lifecycle from concept through hardware delivery.
• Advanced proficiency with CAD modeling software, preferably Creo, and experience with Windchill or similar PLM/configuration management systems.
• Applied experience with ASME Y14.5 GD&T standards and development of engineering drawings, bills of materials, work orders, assembly procedures, and test documentation.
• Expertise in mechanism design principles and machine elements, including bearings, gear trains, stepper and brushless DC actuators, motors, lubrication systems, seal systems, release mechanisms, and robotic systems.
• Experience performing mechanism analyses including bearing and gear calculations, force and torque margin assessments, tolerance analyses, and dynamic or motion-system evaluations.
• Experience developing requirements, verification approaches, and performance specifications for mechanical and electromechanical systems.
• Experience planning and executing functional, vibration, thermal-vacuum, environmental, and life-cycle testing of mechanism hardware.
• Familiarity with spaceflight hardware procurement, supplier management, manufacturing processes, and delivery of flight or high-reliability hardware.
• Demonstrated ability to work effectively on multidisciplinary engineering teams with strong…
