Annapurna Labs is at the forefront of hardware/software co-design, not just in Amazon Web Services (AWS) but across the industry. We design and build every component of our hardware and software to create products that our customers use for accelerated computing. If you're interested in the work required to build the highest-performing Machine Learning servers, from inception to delighted customers, Annapurna is a fantastic choice.We are seeking an experienced CPLD/FPGA Firmware Engineer to join our ML Acceleration Server Firmware team, which is responsible for developing firmware to enable power sequencing and developing control systems for ML Acceleration servers in the data center. The team focuses on deploying firmware to diverse environments, including pre-silicon emulation, hardware manufacturing, automated testing, and production systems used by customers.Technologies useful to this role include computer architecture, hardware description languages (HDLs), and embedded systems. Our team uses Verilog, C, C++, Lua, bash, Python and other similar languages. Although we use machine learning workloads to validate systems software, this team is focused on codeveloping reliable server software and hardware for customers to deploy their ML workloads at scale.Key job responsibilities- Develop CPLD and FPGA programs that implement power sequencing and manage various protocols, including PWM, I2C, and SPI- Develop systems software, kernel drivers- Define test and automation flows to validate firmware- Evaluate and optimize firmware performance- Build error detection and recovery mitigation systems at AWS scaleA day in the lifeYou will have the opportunity to develop server firmware in a highly cross-functional environment, working side by side with software and hardware teams to optimize customer experience. You will be responsible for building scalable designs that can be tested throughout the stages of product development including manufacturing and production. You will leverage automation, continuous integration, and fleet metrics to deploy and monitor your changes.About the teamAmazon Web Services (AWS) is the world’s most comprehensive and broadly adopted cloud platform. We pioneered cloud computing and never stopped innovating — that’s why customers from the most successful startups to Global 500 companies trust our robust suite of products and services to power their businesses.Inclusive Team CultureHere at AWS, it’s in our nature to learn and be curious.
