Lead Mechanical Engineer - Space Mechanisms

Barrios Technology Ltd.; Glen Burnie (MD); On-site; USD 110,000 - 170,000; Full time

Job summary

Barrios Technology is seeking a Mechanical Engineer (Mechanisms) to lead the design, development, integration, and verification of spacecraft mechanisms for NASA and commercial spaceflight programs. You will own requirements, drive design maturation, PROCUREMENT, and delivery while coordinating across engineering teams.

The role emphasizes CAD/PLM proficiency, GD&T expertise, and experience with bearings, geartrains, actuators, and testing across multiple life-cycle stages.

Qualifications

• BS degree in Mechanical Engineering; 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.
• 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, geartrains, 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 written, verbal, and technical communication skills.

Responsibilities

• Lead 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.
