• Serve as the primary owner of all hardware-related lab infrastructure, including equipment, fixtures, tooling, and test assets.
• Design, develop, and maintain mechanical fixtures, tooling, and test equipment, and manage associated 3D models, assemblies, detailed drawings, and engineering documentation.
• Build, integrate, troubleshoot, and maintain robotic hardware systems, sensors, and electromechanical assemblies.
• Operate, maintain, and support large-scale test infrastructure, including gantry systems used to simulate real-world environments and robotic operating conditions.
• Develop and execute test plans to validate hardware performance, reliability, durability, and functionality.
• Analyze test results, identify root causes of failures, and drive effective corrective actions.
• Collaborate closely with a Software Engineer to implement and improve automated test solutions.
• Support prototype development, hardware rework, fixture fabrication, and engineering validation activities.
• Establish and improve test procedures, safety practices, documentation standards, and operational workflows within the lab.
• Manage lab equipment, inventory, calibration schedules, and overall test readiness to ensure consistent availability and reliability of test resources.
• Communicate test status, findings, risks, and recommendations clearly to engineering stakeholders.
• Drive projects and lab initiatives from concept through execution with minimal oversight, demonstrating strong ownership and accountability.

Essential Skills

• Strong mechanical engineering fundamentals with the ability to apply them to robotic hardware systems and test environments.
• Hands-on experience working in a mechanical or robotics test laboratory setting.
• Advanced CAD skills, particularly proficiency in SolidWorks for 3D modeling, assemblies, and detailed mechanical drawings.
• Proven ability to design, develop, and maintain mechanical fixtures, tooling, and test equipment.
• Experience building, integrating, troubleshooting, and maintaining robotic hardware systems, sensors, and electromechanical assemblies.
• Capability to develop and execute structured test plans focused on performance, reliability, durability, and functionality.
• Skill in analyzing test data, identifying root causes of failures, and driving corrective actions.
• Strong communication skills to convey test results, risks, and recommendations to technical stakeholders.
• Demonstrated proactive problem-solving skills and a strong bias for action.
• Ability to work with minimal oversight and take full ownership of lab infrastructure and projects.

Additional Skills & Qualifications

• Experience operating and supporting large-scale test infrastructure, such as gantry-based systems that simulate real-world operating conditions.
• Background in mechanical design for robotics, including fixture and tooling design.
• Familiarity with establishing and improving test procedures, safety practices, and documentation standards.
• Experience collaborating closely with software engineers to develop and refine automated test solutions.
• Ability to manage lab inventory, calibration schedules, and equipment readiness.
• Strong organizational skills and attention to detail in maintaining engineering documentation and lab workflows.

Work Environment

The Mechanical Test Engineer works primarily in a robotics test laboratory environment that houses robotic systems, sensors, electromechanical assemblies, and large-scale gantry-based test infrastructure designed to simulate real-world operating conditions.
