Work History
Electrical Engineer II
Chamberlain Group
01.2022 - 09.2025
- Partnered with leading companies to evaluate product reduced costs redesigns without compromising quality, achieving up to $300K in manufacturing cost savings.
- Drove multiple projects to completion by setting clear goals, prioritizing tasks, and delivering five final products with critical and innovative design enhancements.
- Mentored junior engineers, sharing technical expertise and providing guidance on best practices in the industry.
- Redesigned PCB layouts up to 8 layers, mitigating EMI, EMC, and crosstalk issues (e.g., integrating dual footprints in narrow spaces), while migrating technologies from TH to SMT for transmitters, RF ICs, and power supplies, ensuring compliance with DFM and DFT requirements.
- Lead engineer of four multidisciplinary projects involving electronic critical parts with an annual demand up to three million (BJT, ICs, IRM, OPAMPS, inductors).
- Led product migration from India and USA to Mexico facilities, providing technical support and driving new product introductions while managing and executing multiple tasks in parallel.
- Managed and tested up to 50 components through value and component engineering to enhance product performance and address client compliance notices (CCNs).
- Executed and supervised reliability testing of products and components in compliance with NEMA, UL, and CE standards.
- Validated product and subsystem performance through simulation and laboratory testing.
- Delivered comprehensive technical documentation for high-volume products, including schematics (SCHs), PCB fabrication drawings, BOMs, component drawings, PPAPs, DFMEAs, hardware specifications, and design validation test reports.
- Excelled in supporting manufacturing line-down situations of electronic components by performing electronic circuit analysis, conducting GAP analysis of critical parameters, and identifying viable alternatives to meet design applications
- Collaborated with global multidisciplinary, cross-functional teams to align, track, and deliver hardware design projects and product development initiatives.
- Provided technical support to colleagues on complex issues, assisting them in finding efficient solutions to problems.
- Evaluated vendor proposals for new equipment purchases, making recommendations based on performance criteria and budget constraints.
- Consistently met project deadlines by efficiently managing time and resources, ensuring timely completion of tasks.
