A Principal Engineer is sought to lead the architecture, design, and integration of SoC-wide clocking networks, including PLLs and DLLs. This role involves defining and optimizing power-performance-area trade-offs, collaborating with various engineering teams, and owning the technical roadmap for clocking and timing closure. The ideal candidate will have 15-20 years of hands-on experience in SoC clocking, custom circuit design, and timing architecture, with expertise in clock tree synthesis, low-power techniques, and transistor-level design. Mentoring junior designers and ensuring robust silicon correlation are also key responsibilities.
