About the role
- Join Astera Labs' Signal Connectivity Engineering team as a Principal Engineer shaping the firmware and software that makes advanced connectivity products adaptive, reliable, and production-ready.
- This is a high-impact role at the intersection of embedded systems, mixed-signal hardware, and Ethernet physical-layer behavior.
- You will work across architecture, lab debug, automation, and customer integration while partnering with silicon, analog, systems, validation, and applications teams.
Responsibilities
- Own the embedded firmware stack from hardware abstraction and device drivers through management interfaces, diagnostics, and customer-facing APIs.
- Design firmware for adaptive equalization, gain control, calibration, link training, PLL/CDR feedback, thermal management, and device telemetry.
- Architect control algorithms, state machines, and tuning flows that manage analog and high-speed interfaces across process, voltage, and temperature variation.
- Investigate register accesses, embedded SDK behavior, link state machines, PHY telemetry, logs, and real-hardware measurements to identify root causes and deliver targeted fixes.
- Partner with system validation to develop test plans, automate characterization flows, and verify firmware across corner cases and product configurations.
- Support customer bring-up, field issue triage, and deployment readiness in collaboration with applications, platform, and silicon teams.
- Set technical direction, lead architecture and tradeoff discussions, and balance performance, code size, maintainability, and time to market.
Compensation
- Occasional travel to Astera Labs' San Jose headquarters, approximately twice per year, for chip bring-up and project coordination
