About the role
As a Principal Infrastructure Hardware Engineer, you will architect, design, and deliver system platforms supporting characterization, validation, ATE, and high-volume manufacturing of SiTime products. This is an individual contributor technical leadership role focused on deep technical ownership and cross-functional influence across hardware teams.
What you'll do
- Own end-to-end system hardware design from architecture through production release, including schematics, PCB stack-ups, and layout constraints. - Lead SI/PI, PDN design, and advanced simulations for low-jitter, high-speed interfaces. - Drive DFM, DFA, and DFT reviews with fabrication and assembly partners. - Lead hands-on prototype bring-up, debug, characterization, and system-level failure analysis using lab equipment including oscilloscopes and phase-noise analyzers. - Develop modular, reusable platforms supporting multiple product lines while driving component selection and vendor strategy. - Act as a technical mentor and design reviewer across hardware teams, communicating technical status, risks, and trade-offs.
What you'll need
- MS in Electrical Engineering or equivalent experience. - 7+ years of hands-on experience designing complex system hardware for high-volume products, delivering hardware from concept through production. - Deep expertise in board, package, socket, and manufacturing technologies. - Strong SI/PI, high-speed digital, and mixed-signal design experience. - Proficiency with OrCAD, Allegro, ADS, HFSS, or equivalent tools. - Experience working with ODM/OEM partners and external compliance labs.
