Astera Labs is seeking an experienced firmware engineer to develop embedded firmware that brings compute connectivity silicon to life, from boot and initialization through link management and diagnostics.
The role involves owning features end to end in both pre-silicon emulation environments and in the lab with real silicon.
Candidates will collaborate closely with architects, design and verification engineers, validation teams, and global firmware teams to take products from early development through bring-up and customer deployment.

Design, implement, and maintain real-time embedded firmware in C for high-performance connectivity
Develop low-level drivers, initialization flows, interrupt handling, and control logic for complex hardware blocks
Bring up and debug firmware in pre-silicon environments (emulation) ahead of tape-out, and on silicon after it arrives
Work closely with architecture, design, and verification teams to define HW/FW interfaces and to resolve issues across the hardware/software boundary
Triage and resolve firmware issues reported by validation, product applications, and customers
Take part in design reviews and code reviews, and help improve our firmware quality, tooling, and development practices
Develop and extend the company SDK, including APIs, device management, firmware update, telemetry, and diagnostics capabilities, and keep it aligned with firmware features
Support customer requests and engagements together with product applications and field teams, analyze system-level use cases, and adjust firmware and SDK development to meet customer needs
Collaborate with firmware teams across sites to deliver features on schedule

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
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
A team player with excellent communication skills who works well in a collaborative, cross-site environment
Comfort with ambiguity and ownership in a fast-moving, high-growth company
