Mechanical Engineer

Mechanical Engineer

This role focuses on sustaining and improving battery testing equipment, test stands, and supporting infrastructure to ensure safe, reliable, and high-performance test operations. The mechanical engineer will diagnose and resolve equipment failures, drive root cause analysis, and implement long-term design improvements in collaboration with cross-functional engineering teams.

• Diagnose and troubleshoot failures in battery testing equipment, test stands, and supporting infrastructure to restore safe and reliable operation.
• Perform detailed root cause analysis on recurring issues and implement corrective and preventive actions to eliminate failure modes.
• Support technicians and engineering teams in maintaining safe, efficient, and reliable test operations across multiple test stands and systems.
• Repair, replace, and optimize sensors, instrumentation, and mechanical components to improve performance and durability.
• Troubleshoot and maintain air, fluid, thermal, and pressure management systems within test environments.
• Improve system reliability, stability, uptime, and overall test stand performance through systematic problem-solving and continuous improvement.
• Identify recurring failure modes and collaborate with design teams to implement long-term improvements, redesigns, and design-for-reliability enhancements.
• Maintain and update CAD models, bills of materials (BOMs), work instructions, repair records, and technical documentation to reflect current configurations and standards.
• Optimize sensor integration, data acquisition systems, and test infrastructure performance to ensure accurate and robust testing.
• Collaborate effectively with test, controls, electrical, and other cross-functional engineering teams to deliver integrated solutions.
• Apply structured problem-solving techniques while balancing speed, rigor, and safety in a fast-paced environment.
• Communicate findings, recommendations, and status updates clearly to stakeholders, technicians, and engineering peers.

• At least 5 years of experience in sustaining engineering, mechanical design, or test engineering with significant hands-on troubleshooting and root cause analysis work.
• Strong hands-on troubleshooting and root cause analysis skills for complex mechanical and test systems.
• Proficiency in Solid Works or similar CAD tools such as NX for mechanical design and documentation.
• Experience working with sensors, instrumentation, and data acquisition systems in test or industrial environments.
• Knowledge of air, fluid, thermal, and mechanical systems relevant to test stands and industrial equipment.
• Background supporting industrial, manufacturing, battery, or energy systems.
• Ability to collaborate effectively with test, controls, electrical, and cross-functional engineering teams.
• Strong focus on improving equipment reliability, uptime, and overall system performance.
• Demonstrated problem-solving skills with the ability to balance speed, rigor, and safety.
• Strong communication and collaboration skills, with the ability to work cross-functionally in a fast-paced environment.
• Self-driven mindset with a passion for solving complex technical problems.

• Familiarity with finite element analysis (FEA) tools and methods is a plus.
• Experience integrating sensors and instrumentation into complex mechanical or test systems.
• Exposure to battery testing, energy systems, or related high-performance test environments.
• Experience maintaining and improving technical documentation such as BOMs, work instructions, and repair records.
• Comfort working closely with technicians and operators to translate field issues into engineering solutions.
