Power Delivery Architect
Who we are:
Persimmons is building the infrastructure that will power the next decade of AI. Founded in 2023 by veteran technologists from the worlds of semiconductors, AI systems, and software innovation, We're on a mission to enable smarter devices, more sustainable data centers, and entirely new applications the world hasn't imagined yet.
Why join us:
We're growing fast and looking for bold thinkers, builders, and curious problem-solvers who want to push the limits of AI hardware and software. If you're ready to join a world-class team and play a critical role in making a global impact - we want to talk to you.
What you'll do:
As a Senior Power Delivery Architect, you will be responsible for designing the complete power delivery system for Persimmons' AI accelerator — a grid of hundreds of chiplets drawing thousands of amps from a 48V datacenter rack and delivering clean, stable power to silicon cores operating at sub-1V. This is not a standard board power project. Your primary duties and responsibilities include:
- Architect the rack-to-silicon power delivery network, designing the complete roadmap from 48V datacenter busbar power down to sub-1V silicon cores across a multi-chiplet grid at hyperscale.
- Own regulator integration strategy — evaluating and deploying high-frequency, multi-phase VRMs, Co-packaged Voltage Regulators (CPVR), and Vertical Power Delivery (VPD) archi
