Dear Hiring Manager,

I am writing to express my interest in the Hardware Validation Engineer position with your company. With 3 years of experience in wireless systems and telecommunications, I am currently employed as a Design Validation Engineer at Halliwell in Ohio. In this role, I am responsible for testing RF electrical designs, wireless system blocks, and protocol developments for wireless products. I collaborate with system designers and architects to ensure designs meet client requirements.

Prior to my current role, I worked as an RF Engineer at WowTech, where I designed, tested, commissioned, and optimized wireless networks for mobile operators and equipment manufacturers. I hold a BS in Electrical Engineering and have a strong understanding of RF design principles, process improvements, and testing methodologies. I am proficient in working with major DAS OEMs such as Corning, Commscope, ADRF, TE, SOLiD, and JMA/TEKO, as well as designing small cells using Nokia MBO, Ericsson DOT, and SpiderCloud.

I have attached my résumé for your review and consideration. Thank you for your time and I look forward to the opportunity to discuss how my skills and experience align with the needs of your team.

Sincerely,
Jeffrey Chang
