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.\nThe Role and Its Impact\nOur 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.\nWe 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.\nWhat You'll Be Doing\nHaving fun! by being part of a very strong and cohesive group.\n\nDesign, implement, and maintain real-time embedded firmware in C for high-performance connectivity\n\nDevelop low-level drivers, initialization flows, interrupt handling, and control logic for complex hardware blocks\n\nBring up and debug firmware in pre-silicon environments (emulation) ahead of tape-out, and on silicon after it arrives\n\nWork closely with architecture, design, and verification teams to define HW/FW interfaces and to resolve issues across the hardware/software boundary\n\nTriage and resolve firmware issues reported by validation, product applications, and customers\n\nTake part in design reviews and code reviews, and help improve our firmware quality, tooling, and development practices\n\nDevelop and extend the company SDK, including APIs, device management, firmware update, telemetry, and diagnostics capabilities, and keep it aligned with firmware features\n\nSupport 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\n\nCollaborate with firmware teams across sites to deliver features on schedule\n\nWhat We're Looking For\nRequired:\nBSc/MSc in Computer Science, Electrical Engineering, Computer Engineering, or a related field\n\n10+ years of hands-on experience as a firmware engineer\n\nProven experience in embedded and real-time firmware development\n\nStrong programming skills in C on resource-constrained, bare-metal, or RTOS-based systems\n\nSolid understanding of processor architecture, memory-mapped registers, interrupts, and HW/SW interaction\n\nStrong debugging skills on real hardware using JTAG debuggers, logs, and register-level analysis\n\nBroad system-level understanding of how silicon, firmware, SDK, host software, and platform interact, with the ability to turn customer requirements into technical solutions\n\nA team player with excellent communication skills who works well in a collaborative, cross-site environment\n\nComfort with ambiguity and ownership in a fast-moving, high-growth company\n\nAdvantage:\nExperience with pre-silicon emulation platforms such as Cadence Palladium or Synopsys ZeBu\n\nKnowledge of PCIe (link training, enumeration, configuration space, error handling)\n\nExperience developing SDKs, host-side libraries, or APIs (C/C++ or Python) that interface with embedded firmware\n\nExperience working directly with customers or supporting customer integration and field issues\n\nExperience with silicon bring-up of new SoCs\n\nPython scripting for test automation, debug, or data analysis\n\nFamiliarity with Linux development tools (gcc/clang, make, bash, gdb, git) and CI workflows\n\nWe 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.","description_format":"text","description_chars":4970,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Processors,
