About Ampere

Ampere is a semiconductor design company founded in 2017, headquartered in Santa Clara, designing CPUs and related silicon IP for cloud infrastructure and edge AI. The company focuses on high-performance, power-efficient compute architectures built on ARM instruction sets. Current project work spans physical design (PCB/package guidelines), post-silicon validation and test yield optimization, power management circuits, and open-source JTAG/debug tooling for their custom ARMv9 SoC. Manufacturing and supply-chain hiring (6 roles + Director-level procurement position) indicates movement toward foundry partnerships and volume production. The engineering org (79 roles) dominates headcount, with targeted growth in data and finance—typical of a company scaling from design through manufacturing ramp.
