Required PHY System Technical Leader
Job Description
Join the PHY system team at Silicon One, a pivotal part of our silicon development. Our team focuses on the PHY and system aspects of our devices, including PHY firmware, calibrations, system definitions, operations, and post-silicon validation.
Key responsibilities include:
Working with the latest silicon technologies and processes to build large-scale, complex devices at the forefront of feasibility.
Contributing to the development of PHY firmware and system calibrations.
Participating in system definitions, operations, and post-silicon validation activities.
What Youll Do:
Youll be part of the group driving next-generation network devices-Silicon One-within a startup-like atmosphere inside a well-established, leading corporation.
Our unique design center integrates all silicon hardware and software development disciplines under one roof. We are revolutionizing the industry by building a new internet for the 5G era, with a unified, programmable silicon architecture that will underpin our future routing products. Our devices are designed for adaptability across service providers and web-scale markets, delivering high speed without compromising programmability, buffering, power efficiency, scale, or feature flexibility.

In this role you will develop system level software, targeting chip architecture, functional correctness and performance, running on various platforms and validating chip functionality.

We're looking for exceptional engineers to join our Pre-Silicon Verification team - the team that sits at the very center of the chip development lifecycle. Verification in our company isn't a downstream checkpoint - it's the connective tissue that spans the entire product journey:
It starts at product definition - we engage from day one, shaping requirements and translating product intent into verification strategies before a single line of RTL is written
It extends into software - we work side-by-side with SW teams, verifying hardware-software interfaces and ensuring seamless integration across the stack
It reaches into physical design - we verify physical design aspects within functional verification, bridging the gap between logical correctness and silicon reality
It closes the loop - from spec to silicon, our verification touches every team and every stage of chip development
What sets us apart:
Agentic AI is embedded in our workflow - not as an experiment, but as a core part of how we design and verify chips.
Cutting-edge methodologies drive every stage of our verification process
Relentless innovation - we don't settle; we actively seek new approaches that raise the bar on silicon quality.
We do classic functional verification(SV/UVM/TLM), but beyond that, we touch physical design aspects, to ensure that the quality of our silicon is beyond logical functionality.
Performance optimization at all levels it is at the heart of our targets on top of logical correctness verification.
If you want to be at the nerve center of chip development - where your work connects every discipline and powers the backbone of AWS Graviton - this is your team.
