Job summary

Ampere Computing LLC in Santa Clara, CA seeks a Distinguished Circuit Engineer to lead HSIO/SerDes direction for high-speed interfaces on advanced nodes. You’ll own end-to-end specs, drive in-house IP, and collaborate with vendors and foundries to deliver reliable server SoCs.

You will mentor engineers, influence roadmaps, and ensure robust post-silicon validation and production readiness across Die-to-Die, memory, and peripheral IOs.

Qualifications

• Proven leadership in high-speed SerDes and mixed-signal PHY silicon development.
• Experience taking complex SerDes (PAM4/NRZ, D2D, PCIe, DDR, or UCIe) from concept to high-volume production on advanced nodes.
• Deep expertise in analog/mixed-signal design (TX/RX, PLLs, clocking, equalization) across PVT corners.
• Strong knowledge of high-frequency signaling, PDN, crosstalk, and package parasitics.
• Hands-on post-silicon validation using lab instruments and automated test flows.
• Excellent cross-functional communication and vendor/foundry collaboration.

Responsibilities

• Define the technical roadmap for HSIO/SerDes, IP development, and integration of server SoCs.
• Lead in-house IP design and manage external IP partnerships with vendors and foundries.
• Specify detailed IP electrical, functional, and timing requirements with SoC and packaging teams.
• Guide circuit architectures (analog/mixed-signal) and oversee end-to-end implementation from spec to production.
• Directed post-silicon characterization, debugging, and yield-focused validation.
• Mentor engineers, influence leadership, and align roadmaps across organizations.
