Senior Firmware Engineer

Overview

Astera Labs is seeking a Senior Firmware Engineer to develop and deliver core firmware for our next-generation connectivity, chiplet, and system products. Firmware is a core differentiator for Astera Labs’ products and is treated as a first-class engineering discipline, on par with hardware and silicon design. 

Key Responsibilities 

• Architect, develop, and maintain bare-metal and low-level firmware running on embedded microcontrollers within Astera Labs SoCs and systems.
• Design and implement device drivers, core firmware services, and hardware abstraction layers for high-speed connectivity products.
• Define and implement HW-SW interfaces in close collaboration with RTL, PD, and Architecture teams.
• Lead bring-up, debug, and validation of firmware on silicon and system platforms.
• Develop and maintain C/C++ firmware codebases, SDKs, and supporting infrastructure.
• Build automation, tooling, and diagnostics using Python and scripting frameworks.
• Participate in system-level debug involving PCIe, Ethernet, memory subsystems, and interconnect fabrics.
• Support customer enablement, integration, and escalations as needed.

Basic Qualifications

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or related field (Master’s preferred).
• Strong fundamentals in embedded systems, computer architecture, and low-level software.
• Proven experience developing firmware for complex SoC or silicon-based products in Server, Storage, Networking, or Accelerator environments.
• Proficiency in C (required); C++ experience is a plus.
• Ability to work cross-functionally in a fast-paced, highly technical environment.

Required Experience

• Bare-metal or RTOS-based firmware development (e.g., ThreadX, MQX, or equivalent).
• Firmware development for on-chip microcontrollers and supporting SDKs.
• Strong debugging skills across hardware, firmware, and system layers.
• Familiarity with firmware build systems and tooling (gcc, Make, Git, Doxygen).
• Python scripting for automation, validation, or tooling.
• Hands-on experience with server, storage, or networking systems.

Preferred Experience / Nice to Have

• Firmware development for PCIe or Ethernet switch products.
• Exposure to BMCs, OpenBMC, or system management firmware.
• Experience with high-speed interfaces such as:
  • PCIe (Gen3+)
  • Ethernet (100G / 400G+)
  • NVMe, Infiniband
• Participation in industry forums or ecosystems (e.g., OCP, OpenBMC).
• Customer-facing or field-enablement experience.

Salary range is $160,000 to $195,000 depending on experience, level, and business need. This role is eligible for discretionary bonus, incentives, and benefits.
