Core Responsibilities

Primary Functions

Execute complex functional, performance, and system-level tests on a wide range of electronic circuit boards, modules, and finished products using established procedures.
Set up, configure, and operate standard and specialized test equipment, including oscilloscopes, digital multimeters, spectrum analyzers, power supplies, and function generators.
Diagnose, troubleshoot, and identify the root cause of failures in electronic assemblies down to the component level by interpreting schematics, block diagrams, and technical documentation.
Perform precise rework and repair on printed circuit board assemblies (PCBA), including fine-pitch surface mount (SMT) and through-hole soldering/desoldering.
Meticulously record and document all test results, failure data, and troubleshooting steps in the manufacturing execution system (MES) or quality database.
Read, interpret, and work from complex engineering drawings, schematics, assembly drawings, and work instructions to perform testing and validation tasks.
Operate and monitor Automated Test Equipment (ATE) systems, executing pre-defined test scripts and analyzing automated reports for anomalies.
Conduct environmental stress screening (ESS), including thermal cycling and vibration testing, to ensure product robustness and reliability under various conditions.
Perform First Article Inspection (FAI) on new product introductions (NPI) to validate the manufacturing and testing process against design specifications.
Collaborate directly with design, manufacturing, and quality engineers to provide detailed feedback on test failures, product testability, and potential design improvements.
Generate comprehensive test reports, failure analysis summaries, and yield data for review by engineering and management teams.
Maintain and perform basic calibration and verification of test stations, fixtures, and associated equipment to ensure measurement accuracy and consistency.
Adhere strictly to all electrostatic discharge (ESD) handling procedures and safety protocols within the test and manufacturing environment.
Flash firmware, install drivers, and configure software on units under test as a prerequisite for functional validation.
Visually inspect PCBAs for manufacturing defects such as poor solder joints, component placement errors, and physical damage prior to and after testing.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis to investigate trends in product failures.
Contribute to the organization's continuous improvement initiatives by suggesting enhancements to test procedures, fixtures, and overall workflow.
Collaborate with business units to translate data needs into engineering requirements by providing practical feedback from the test floor.
Participate in sprint planning and agile ceremonies within the data engineering team when developing new test software or processes.
Assist in the training and mentoring of junior technicians on test methodologies, equipment operation, and safety standards.
Manage inventory of test components, lab supplies, and equipment, initiating purchase requisitions as needed.
Participate in Material Review Board (MRB) meetings to provide technical input on the disposition of non-conforming materials.
Assist engineers in the development, validation, and documentation of new test procedures and test fixture designs.
