Sr. Engineer, Ethernet IP
TenstorrentJob Title
Sr. Engineer, Ethernet IP
Role Summary
Engineer the firmware and bring-up for Ethernet MAC/PHY/SerDes subsystems that connect Tenstorrent AI silicon to high-performance networks. Work at the hardware-software boundary with silicon architects, RTL teams, and network software to enable and optimize link training, auto-negotiation, and performance tuning on large-scale platforms.
Experience Level
Senior. The posting is for a senior-level engineer; the company may adjust level during interview and considers a range of seniorities. Specific years of experience are not listed.
Responsibilities
Primary responsibilities focus on low-level firmware, silicon bring-up, and debugging of network subsystems.
- Develop and maintain bare-metal firmware to control Ethernet MAC, PHY, and SerDes components.
- Drive silicon bring-up, lab validation, and troubleshooting of networking subsystems.
- Implement and optimize link-training algorithms and auto-negotiation protocols.
- Debug hardware-software interactions, including signal-integrity and protocol timing issues using lab instruments.
- Collaborate with silicon architects and RTL designers to influence future networking hardware from a firmware perspective.
Requirements
Must-have technical skills and proficiencies.
- Experience writing low-level/bare-metal firmware for Ethernet MAC/PHY/PCS and SerDes components.
- Proven track record of silicon bring-up and lab validation of networking subsystems.
- Knowledge of link-training, auto-negotiation, and Ethernet protocol behavior.
- Hands-on debugging using oscilloscopes, logic analyzers, or similar lab equipment to diagnose signal and timing issues.
- Ability to translate hardware constraints into software/firmware requirements and communicate with RTL and network software teams.
- Strong problem-solving skills for complex hardware-software interactions.
Nice-to-have:
- Experience with high-performance compute or AI platform networking.
- Familiarity with RISC-V systems or firmware for custom silicon.
Education Requirements
