Work History
Design Verification Engineer
Andrews Cooper Technology
04.2025 - 07.2025
- Analyzed Risk Assessment of the new product development based on IEC 61010 safety standard.
- Verified the protocols of the new product development for correctness against the Product Design Input and IEC 60601 standard requirements.
Design Verification Engineer
Meta
06.2021 - 03.2025
- Set up the Spectroradiometer and Colorimeter to test the prototypes of LED indicators which were pin LED's, bar LED's or ring LED's. The tests were performed with different diffuser coatings, different spacers. Analyzed the data of light spectrum, brightness, wavelength regarding the optical performance to the Product Development team.
- Performed the LED indicator tests of the smart glasses at different colors, different angles and different intensities. Analyzed, summarized and visualized the results to the Development team.
- Set up the light booth at different light sources such as D65, Florescent, LED to test the smart glasses ALS (ambient light sensor). Analyzed the sensor performance at different light sources and reported to the Development team.
- Set up the environmental chamber at different altitudes (pressures) and temperatures to test the Barometer sensor.
- Set up the station to test SAR sensor (Specific Absorption Rate) to check the required distances from the glasses when near a human for the minimum power that was radiated.
- Run the environmental tests with extreme temperatures (hot and cold) with high humidity.
- Did the thermal characterization of smart glasses frames heated at different power. Tests were performed inside the thermal chamber. Thermal images and data from thermocouples were collected to the design team.
Hardware Test Engineer
Protingent
07.2019 - 03.2021
- Set up and executed the System test plans which were focusing on the area of thermal performance/characterization.
- Ran user scenarios, and worst cases at different ambient temperatures. Collected and analyzed data for thermal tuning, thermal safety verification, electrical power supply testing, power distribution and power consumption.
- Collected data and ran reports to ensure products meet and exceed defined targets necessary for excellent customer experience.
- Identified and reported problems related to thermal to Design Validation Engineer (DVE).
HW Design Assurance Engineer
Kestra Medical
09.2018 - 06.2019
- Developed detailed and well-structured test cases and protocols to verify the product hardware specifications and requirements including thermal conductivity, humidity, shock, vibration, water ingress.
- Run essential functional tests to ensure the product requirements complying with all current regulatory and safety requirements.
- Supervised and provided technical support to test technicians and other verification engineers to conduct and execute the verification plans.
- Generated Installation Qualification, Operation Qualification, and Performance Qualification for production End Item Test System.
Senior Operations Engineer
Spacelabs Healthcare
11.2007 - 05.2014
- Participated in a new product introduction (NPI). Provided Designed for Test (DFT). Recommended to the PCBA design team to have more test points to achieve more than 95% test coverage.
- Spearheaded of PCBA functional test projects. Created Test Requirement Specifications. Provided sufficient technical information to Test Service Company to develop test systems, and test programs.
- Replaced the Manual Functional test for the Patient Monitor by the Automated Test program, and able to reduce test time by 50%.
- Wrote semi-automated test programs using NI (National Instruments) development suite to qualify PCBA for First Production Run.
- Supported production. Troubleshot all issues related to electrical, mechanical, and process. Provided feedback to Engineers for correction and improvement.
- Developed VBA programs to query data from Quality databases such as Complaint Database and Non-Conforming Report Database. Routinely run the report for defect trending prevention, and process improvement.
- Created Lab Windows CVI program to automate the process of setting the configuration of Anesthesia system based on the Sales Order.
- Modified LabVIEW test programs to incorporate with the design change and the component change.
- Created test programs to verify and configure the alert lighting PCBA, Flow Meter, Flow Controller, Pressure Regulator used in Anesthesia system.
