Work History
Field Service Engineer
Ushio America
01.2023 - Current
Coordinated onsite technical support for semiconductor photo lithography operations to maintain optimal equipment service and maintenance.
primary contact on customer site for equipment malfunction and repair issues.
repairing electro-mechanical vacuum systems
monitoring photo lithography tool performance, along with maintenance and service
Refined process specifications and design improvements by devising procedures and documents, executing redlines on existing procedures, and performing manufacturing process audits for improved quality assurance.
Set up and commissioned precision light-source equipment to support accurate alignment calibration and verify performance.
Resolved electrical, mechanical, and optical failures to bring equipment functionality back online with minimal service disruption.
Recorded service actions alongside repair findings and parts usage in detailed field reports.
Lead Associate Test Engineer
Onto Innovation
01.2017 - 12.2023
Perform set-up, calibration, and testing of Semiconductor Metrology subsystems as well as integration of the entire system while dealing with complex issues that may occur. Works with engineering to analyze causes to the problem.
Assess root cause of Out-of-Box-Quality issues in the field and implement preventative measures. Includes working closely with engineering to draft and redline documents and providing several training sessions to manufacturing team.
Direct supervision of Subassembly and Stage assembly departments. Tracking of escalations and personnel technical support. Management interface and logistical support to ensure manpower and project timeline met customer orders. Constant improvement of lean manufacturing and 5S shop practices.
Test Engineer II
PLEXUS
01.2014 - 12.2017
Development of protocol testing and manufacturing portable medical ultra sound devices, FDA-approved Automated Breast Ultrasound screening systems, and production of systems used for multiplexing diverse DNA, RNA, and epigenetic applications
Engaged with customer to discuss product requirements for mass production.
Initial first pass yield was 30%; latter doubling to 78%.
By troubleshooting at component level, was able to rule out part and design flaws. Saving time from rework and cost by switching to a more suitable vendor.
Utilized statistical failure analysis Pareto to identify and resolve a false failure impacting numerous production units, leading to design modifications for test equipment and a 30% improvement in first pass yield.
Refined processes and protocols, enabling smooth product transfer to mass production facility; engaged with customers to clarify project requests and provide consistent updates on progress.
Develop procedures and required tools for system test, for both Development and Mfg.
Develop product configurations and methods utilizing company ERP systems
Support design reviews to ensure that parts can be manufactured efficiently and in compliance with customer requirements
Developed functional test procedures for electronics assemblies, ensuring reliable production validation.
Troubleshot failing test stations, isolating hardware, software, and fixture issues quickly.
Associate Test Engineer
KLA TENCOR (Superior Technical Resources)
01.2010 - 12.2014
Collaborated with engineering team to set up, calibrate, and test defect inspection and metrology equipment solutions to ensure quality standards.
Supported development of tailored optical alignment process, facilitating cost and time savings and contributing to on-time delivery.
Developed and led a cross-functional training program for offshore manufacturing staff, enhancing output and skills integration.
documentation and procedure handbook serving as rapid learning aid.
Executed semiconductor test procedures to validate equipment performance and measurement accuracy.
Developed automated test scripts using LabVIEW and Python for repeatable device characterization.
Communications Vehicle Test Engineer
SPACE SYSTEMS/LORAL
01.2005 - 12.2009
Manufactured and integrated high- powered satellites and satellite systems, providing solutions that meet the requirements of an international base of commercial and governmental customers in a fast-paced team environment.
Coordinated with customer to confirm critical time slot for orbital insertion.
Part shortages were interfering with the build plan. In order to save time in schedule I was able to work with the customer to move major component level testing to subsystem level.
Prior to transfer of Spacecraft to offsite test facility, I implemented a prescreening process that would later save 8-10 days of off-site testing. This was a major cost reduction for the company at this time.
I was able to resolve a single point failure related to test equipment by duplicating a stationary test fixture; I was able to create mobile rack-and-stack setups. This new mobile test fixture would assist in portability as well as eliminate a bottle neck when multiple technicians reached the same point in testing.
Vehicle Test Operations Technician
LOCKHEED MARTIN
01.2003 - 12.2005
Contributed to top secret government aerospace and homeland security projects in RF, electrical, and mechanical domains.
Secured top secret government clearance efficiently to comply with departmental requirements.
Maintained Test Equipment, Tools, Shop Equipment, and Lab Equipment.
Coordinated transport logistics for test vehicles and test equipment to facilitate offsite testing.
Operated production equipment following strict safety, quality, and configuration control procedures.
Inspected components and assemblies to verify compliance with engineering and manufacturing specifications.
