At a glance

Astera Labs is seeking an experienced firmware engineer and PCIe expert to develop embedded firmware that brings compute connectivity silicon to life.
The role involves owning features end to end, working close to the hardware, and developing and debugging firmware both pre-silicon and post-silicon.
You will collaborate with architects, design and verification engineers, validation teams, and global firmware teams to take new products from early development through bring-up and customer deployment.

Having fun! by being part of a very strong and cohesive group.
Design and develop real-time embedded firmware in C, including low-level drivers and control logic for complex hardware blocks.
Own PCIe firmware features end to end: link training, enumeration, error handling, and recovery.
Develop and debug firmware pre-silicon (emulation) and lead post-silicon bring-up and debug in the lab.
Debug complex PCIe and system-level issues with architecture, design, validation, and customer teams.
Develop and extend the company SDK in step with firmware features.
Support customer requests and adjust firmware and SDK development to meet their needs.

BSc/MSc in Computer Science, Electrical Engineering, Computer Engineering, or a related field
10+ years of hands-on experience as a firmware engineer
Proven experience in embedded and real-time firmware development
Strong programming skills in C on resource-constrained, bare-metal, or RTOS-based systems
Solid understanding of processor architecture, memory-mapped registers, interrupts, and HW/SW interaction
Expert-level knowledge of PCIe: LTSSM and link training, enumeration, configuration space, error handling (AER), and reset and recovery flows
Experience with PCIe protocol analyzers and exercisers (e.g., Teledyne LeCroy, Keysight)
Proven hands-on experience in both pre-silicon and post-silicon firmware development and debugging, including silicon bring-up of new SoCs
Strong debugging skills on real hardware using JTAG debuggers, logs, and register-level analysis
Broad system-level understanding of how silicon, firmware, SDK, host software, and platform interact, with the ability to turn customer requirements into technical solutions
