Job Description

We are seeking a talented and motivated Member of Technical Staff (MTS) or Senior Member of Technical Staff (SMTS) Engineer to join our team and drive the development of next-generation discrete power FET technologies. This role offers high technical ownership, cross-functional visibility, and the opportunity to directly shape onsemi's future power device roadmap.

Responsibilities

Responsibilities
  • Lead technology development for onsemi's advanced nodes of discrete power FETs, owning device architecture from concept definition through qualification and high-volume manufacturing.
  • Define electrical targets and device structures, collaborating with design, process integration, and modeling teams to optimize Rds(on), switching performance, ruggedness, and power density.
  • Conduct or direct TCAD, electro-thermal, and compact modeling simulations to predict performance, parasitics, and reliability behavior.
  • Partner with process module owners in the fab to optimize process windows, ensure device robustness, and resolve integration challenges.
  • Perform device characterization, electrical testing, and failure analysis, ensuring compliance with specifications and customer requirements.
  • Drive structured root-cause analysis (DOE, 6-sigma, SPC, FMEA) for yield, reliability, or device-related issues, and implement sustainable corrective actions.
  • Collaborate with systems engineering, product engineering, packaging, and applications teams to integrate power FETs into system-level solutions and end-customer applications.
  • Monitor industry trends and emerging device concepts in power MOSFET, superjunction, and wide-bandgap (SiC/GaN) technologies.
  • Generate invention disclosures, patents, and technical reports to strengthen onsemi's IP portfolio and documentation standards.
  • Provide technical guidance, coaching, and mentorship to junior engineers; matrix-manage engineers across multiple organizations.
  • Present technical content in executive-level reviews and represent the team in cross-functional and customer-facing discussions.
  • Report directly to the Sr. Director of Technology Development
