Systems Test Engineer Jobs in Riverside, CA (NOW HIRING)

Manufacturing Test Engineer

Job Description

The Sr. Manufacturing Test Engineer supports and advances manufacturing test systems for insulin pump products and upcoming commercialization efforts in a type 1 diabetes management environment. This role owns factory acceptance testing systems on the production floor that verify product functionality before shipment. It blends manufacturing test engineering, Python-based test automation, electromechanical troubleshooting, fixture improvement, and close collaboration with R&D, Quality, Manufacturing, and Operations teams. The engineer works on automated test systems that validate multiple functional criteria, including motor performance, current draw, mechanical assembly issues, and overall pass/fail results, and plays a key role in improving system performance, reliability, and scalability.

Responsibilities

• Own and maintain manufacturing test systems used on the production floor, with a focus on factory acceptance testing systems that verify product functionality before shipment.
• Develop, update, and troubleshoot Python scripts for test automation, including test execution, equipment control, data acquisition, and data analysis.
• Validate multiple functional criteria within automated test systems, such as motor performance, current draw, mechanical assembly integrity, and overall pass/fail outcomes.
• Improve existing test systems by tuning test thresholds, refining test methods, and enhancing system reliability and throughput.
• Analyze test results and production data to identify trends, failure modes, and opportunities for process and test optimization.
• Troubleshoot test system issues across hardware, software, process, and test method layers to quickly resolve production-impacting problems.
• Design, modify, and improve hardware and electromechanical test fixtures, nests, and tooling to support robust and repeatable testing.
• Integrate and maintain test hardware components, including DAQ systems, sensors, PLCs, and automation elements within manufacturing test platforms.
• Develop and validate manufacturing test methods and test plans for automated test systems in a regulated medical device environment.
• Collaborate cross-functionally with R&D, Quality, Manufacturing, and Operations teams to support new product introduction, manufacturing scale-up, and process development.
• Support fixture improvement, automation enhancements, and validation activities for current production and upcoming product commercialization.
• Create and maintain technical documentation related to test systems, test methods, fixture designs, and validation protocols.
• Participate in continuous improvement initiatives to increase test coverage, reduce false failures, and improve yield and throughput.
• Act as a hands-on engineering resource on the production floor, working closely with operators and engineering teams to address day-to-day test and equipment issues.
• Contribute to the design and improvement of custom automated equipment and test platforms as needed to support evolving product and manufacturing requirements.

Essential Skills

• Bachelor’s degree in Mechanical Engineering, Electrical Engineering, or a related technical field.
• Minimum of 5+ years of manufacturing test engineering experience, ideally with automated test systems, electromechanical products, or regulated hardware manufacturing.
• Strong Python scripting ability for test automation, including equipment control, data acquisition, test execution, and data analysis.
• Proven experience developing, maintaining, troubleshooting, or improving automated manufacturing test systems.
• Experience with test hardware integration, including DAQ systems, sensors, PLCs, automation components, or similar equipment.
• Ability to troubleshoot complex issues that span hardware, software, manufacturing processes, and test methods.
• Hands-on experience with hardware and electromechanical test fixtures, sensors, and test hardware integration.
• Comfort working at the intersection of hardware, software, manufacturing, and data-driven problem solving rather than in a purely software or purely mechanical role.
• Experience working in a regulated manufacturing environment, preferably medical device manufacturing.
• Knowledge of factory acceptance testing (FAT) concepts and manufacturing test methods for automated test systems.

Additional Skills & Qualifications

• Experience with SolidWorks or other CAD tools for basic fixture, nest, or tooling modifications.
• Experience in designing or improving custom automated equipment and test platforms.
• Experience with SQL, Python-based data analysis, or data visualization tools for production and test data.
• Exposure to MES systems or digital manufacturing integration.
• Experience in medical device manufacturing or other regulated industries such as aerospace and defense.
• Ability to work effectively in a growth-stage environment supporting new product introduction, manufacturing scale-up, and process development.
• Strong analytical skills and attention to detail when tuning test thresholds and validating test methods.
• Effective communication skills for cross-functional collaboration with R&D, Quality, Manufacturing, Operations, and production teams.
• Comfort with documentation and validation activities required in regulated environments.
