## About the role

Astera Labs' Taurus product line includes Ethernet retimers and gearboxes deployed in active electrical cables and in-system applications at the heart of AI infrastructure. As AI clusters scale to tens of thousands of GPUs connected by high-speed Ethernet fabrics, the firmware running on these connectivity devices is mission-critical — and so is the ability to debug it fast when something breaks.

## What they're looking for

- Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or related field
- 5+ years of experience in firmware development or embedded systems engineering
- Hands-on experience with Ethernet at the system or device level: Layer 1 PHY, SERDES, retimers, gearboxes, NICs, switches, or related devices
- Solid embedded C/C++ skills and comfort working in a firmware codebase on real hardware
- Ability to debug across the hardware/software boundary: register accesses, embedded SDKs, link state machines, PHY telemetry, debug print logs
- Familiarity with Linux development tools: gcc/clang, make, bash, gdb, git
