Manufacturing Test Engineer

SiFly • Santa Clara, CA

About The Position

SiFly is seeking a hands-on Manufacturing Test Engineer to develop, deploy, and support production test systems for complex electromechanical products, including PCBAs, embedded electronics, motors and actuators, sensors, communications, and complete systems. The role requires direct experience supporting products through NPI, production ramp, sustained manufacturing, and customer shipment; R&D, prototype, or laboratory-only testing is not sufficient.

The engineer will develop and maintain automated production tests, define test-station architecture and test criteria, and work with Engineering to translate verification methods into production tests. The role also focuses on improving production performance, validating test systems and measurements, supporting traceability and failure analysis, and troubleshooting on the production floor. Modern AI-assisted engineering tools are expected to support development and analysis, with the engineer responsible for reviewing, debugging, validating, and releasing the resulting work.

This is an onsite position in Santa Clara, California, with domestic and international travel as required. The stated pay range is $130,000–$160,000.

Requirements

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Mechatronics, Mechanical Engineering, Manufacturing Engineering, or a related discipline; equivalent relevant technical education and experience may be considered.
• At least 5 years of manufacturing test engineering experience with complex electronic or electromechanical products.
• Direct experience with products built, tested, released, and shipped to customers in a production environment.
• Experience supporting NPI, production launch and ramp, and sustained manufacturing.
• Experience developing production test solutions for PCBAs and electromechanical systems, including test fixtures and station architecture.
• Strong hands-on troubleshooting skills across hardware, firmware/software, electrical, and electromechanical systems.
• Experience with production test instrumentation, test-system validation, GR&R, calibration, test correlation, MES/data collection, and serial-number traceability.
• Ability to use modern AI-assisted engineering/software tools and independently review, debug, and validate AI-assisted outputs.
• Ability and willingness to travel domestically and internationally as required.

Nice To Haves

• Experience with UAVs/drones, robotics, autonomous systems, industrial automation, consumer electronics, or other motorized products.
• Experience testing motors/ESCs, batteries/BMS, sensors, cameras, navigation/RF systems, embedded electronics, and PCBA functional test.
• Experience with contract manufacturers or EMS providers, manufacturing transfers, PFMEA/control plans, and test-system deployment across multiple manufacturing locations.

Responsibilities

• Develop, validate, deploy, and maintain automated production test systems for PCBAs, subassemblies, and finished products.
• Define test-station architecture, protocols, coverage, limits, fixtures, instrumentation, interfaces, software, data collection, and pass/fail criteria.
• Develop, modify, and debug automated test software for DUT communication, instrument control, test sequencing, data acquisition, analysis, and result traceability.
• Partner with Engineering during NPI and Design for Test reviews to convert engineering verification methods into robust production tests.
• Improve test cycle time, throughput, first-pass yield, test coverage, and overall production efficiency.
• Establish test-system validation and measurement controls, including GR&R, correlation, repeatability and reproducibility, calibration, and preventive maintenance.
• Support MES and serial-number traceability, production test records, failure analysis, root-cause investigations, corrective actions, and production-floor troubleshooting.
• Use AI-assisted engineering tools to accelerate test protocols, software development and debugging, station development, failure analysis, data analysis, and documentation, while retaining responsibility for review, validation, and production release.
• Travel domestically and internationally as required to support test-system deployment, production builds, suppliers, and contract manufacturers.
