Astera Labs is at the epicenter of the AI infrastructure revolution, building the intelligent connectivity solutions that power the world's most advanced data centers. As AI workloads scale to unprecedented levels, the demand for purpose-built, rack-scale platforms that seamlessly integrate high-speed connectivity, firmware intelligence, and composable architectures has never been greater — and neither has the opportunity to shape what comes next.

The AI Platform Solutions Group is seeking a Sr. Principal Systems/Rack SW Architect  to serve as the technical visionary for next-generation AI infrastructure, spanning server firmware, high-speed connectivity, and rack-scale system design. In this role, you will define the end-to-end architecture for AI platforms that integrate cutting-edge technologies such as PCIe Gen5/6, UAlink, CXL, composable rack architectures, and advanced interconnect solutions including Astera Labs' portfolio of retimers, switches, and fabric controllers. 

This is a high-impact, high-visibility role where you will drive innovation across silicon integration, platform firmware, system performance, and rack-level orchestration — directly enabling hyperscale AI training and inference workloads. You will partner with silicon vendors, hyperscalers, OEMs, and ODMs while influencing industry standards and mentoring the next generation of platform architects. If you want to architect the future of AI infrastructure at a company that is defining the connectivity backbone of modern data centers, this is your role. 

ASTERA LABS has been transforming computer graphics, PC gaming, and accelerated computing for more than 25 years. It’s a unique legacy of innovation that’s fueled by great technology—and amazing people. Today, we’re tapping into the unlimited potential of AI to define the next era of computing. An era in which our GPU acts as the brains of computers, robots, and self-driving cars that can understand the world. Doing what’s never been done before takes vision, innovation, and the world’s best talent. As an ASTERA LABSN, you’ll be immersed in a diverse, supportive environment where everyone is inspired to do their best work. 

ASTERA LABS has a rapidly expanding ecosystem of data center platform & node designs. From single node HGX/DGX systems all the way up to large multi-node NVLink domain rack architectures. These designs have become core to ASTERA LABS's rapidly growing enterprise and cloud provider businesses. Each bringing together the full power of ASTERA LABS GPUs, ASTERA LABS NVLink, ASTERA LABS InfiniBand networking, ASTERA LABS Grace CPUs, and a fully optimized ASTERA LABS AI and HPC software stack. We're searching for a highly motivated, technical leader to drive the engineering roadmap and innovation for our rack system software architecture. From firmware, kernel drivers, operating systems, networking, fabrics and associated user mode drivers + manageability software. You will work with component leads internally and engage with industry leading hyperscalar / cloud service providers on taking these products to market.
