Who this role is best for

A natural match if you have 10+ years of embedded firmware development experience and are comfortable working across pre-silicon and post-silicon environments.

Best fit for

  • Candidates with 10+ years of firmware development and a track record of end-to-end feature ownership
    — “10+ years of hands-on experience as a firmware engineer”
  • Professionals with experience in silicon bring-up and real-time embedded systems
    — “Bring up and debug firmware in pre-silicon environments (emulation) ahead of tape-out, and on silicon after it arrives”

Things to consider

  • The role demands full attention to detail and system-level thinking, not just isolated firmware tasks
    — “Solid understanding of processor architecture, memory-mapped registers, interrupts, and HW/SW interaction”
  • Candidates must be prepared for global collaboration and cross-site coordination
    — “Collaborate with firmware teams across sites to deliver features on schedule”

How to stand out

  • Highlight experience with silicon bring-up and real-time firmware development in your resume
    — “Bring up and debug firmware in pre-silicon environments (emulation) ahead of tape-out”
  • Emphasize your ability to translate customer requirements into firmware and SDK features
    — “how a customer requirement turns into firmware and SDK”
  • Showcase your work in low-level driver development and control logic for complex hardware
    — “Develop low-level drivers, initialization flows, interrupt handling, and control logic for complex hardware blocks”
  • Demonstrate your comfort with pre-silicon emulation platforms in your application materials
    — “Experience with pre-silicon emulation platforms such as Cadence Palladium or Synopsys ZeBu”
  • Include examples of SDK development or host-side API work in your portfolio or resume
    — “Experience developing SDKs, host-side libraries, or APIs (C/C++ or Python) that interface with embedded firmware”

About the role

Original posting from Astera Labs via Greenhouse

Astera Labs (NASDAQ: ALAB) provides rack-scale AI infrastructure through purpose-built connectivity solutions. By collaborating with hyperscalers and ecosystem partners, Astera Labs enables organizations to unlock the full potential of modern AI. Astera Labs’ Intelligent Connectivity Platform integrates CXL®, Ethernet, NVLink, PCIe®, and UALink™ semiconductor-based technologies with the company’s COSMOS software suite to unify diverse components into cohesive, flexible systems that deliver end-to-end scale-up, and scale-out connectivity. The company’s custom connectivity solutions business complements its standards-based portfolio, enabling customers to deploy tailored architectures to meet their unique infrastructure requirements. Discover more at www.asteralabs.com.

The Role and Its Impact

Our firmware team develops the embedded firmware that brings Astera Labs' compute connectivity silicon to life, from boot and initialization through link management, telemetry, error handling, and diagnostics. This firmware runs on the embedded processors inside our chips and ships in data centers powering AI infrastructure around the world. Beyond the firmware, the team also develops the COSMOS SDK, the software layer customers and internal teams use to configure, monitor, update, and debug our devices in their systems.

We are looking for an experienced firmware engineer who enjoys working close to the hardware, owns features end to end, and is equally comfortable in a pre-silicon emulation environment and in the lab with real silicon. You understand the whole system, not just the chip: how our devices behave inside customer platforms, and how a customer requirement turns into firmware and SDK. You'll work alongside architects, design and verification engineers, validation teams, and our global firmware teams to take new products from early pre-silicon development through bring-up and into customer deployment.

What You'll Be Doing

Having fun! by being part of a very strong and cohesive group.

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

What We're Looking For

Required:

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

Advantage:

Experience with pre-silicon emulation platforms such as Cadence Palladium or Synopsys ZeBu

Knowledge of PCIe (link training, enumeration, configuration space, error handling)

Experience developing SDKs, host-side libraries, or APIs (C/C++ or Python) that interface with embedded firmware

Experience working directly with customers or supporting customer integration and field issues

Experience with silicon bring-up of new SoCs

Python scripting for test automation, debug, or data analysis

We know that creativity and innovation happen more often when teams include diverse ideas, backgrounds, and experiences, and we actively encourage everyone with relevant experience to apply, including people of color, LGBTQ+ and non-binary people, veterans, parents, and individuals with disabilities.
