Job Description
Annapurna Labs (our organization within AWS UC) designs silicon and software that accelerates innovation. Customers choose us to create cloud solutions that solve challenges that were unimaginable a short time agoeven yesterday. Our custom chips accelerators and software stacks enable us to take on technical challenges that have never been seen before and deliver results that help our customers change the world.
We are seeking experienced Hardware Design Engineers to build the next generation of our cloud server infrastructure. Our success depends on our world-class server infrastructure; were handling massive scale and rapid integration of emergent technologies.
As a member of the Machine Learning Acceleration team youll be responsible for the design and optimization of hardware in our data centers. Youll provide leadership in the application of new technologies to large scale server deployments in a continuous effort to deliver a world-class customer experience. This is a fast-paced intellectually challenging position and youll work with thought leaders in multiple technology areas. Youll have high standards for yourself and everyone you work with and youll be constantly looking for ways to improve your products performance quality and cost. Were changing an industry and we want individuals who are ready for this challenge and want to reach beyond what is possible today.
Key job responsibilities
As a Thermal/Mechanical Engineer you design and build the systems that are the heart of the worlds largest and most powerful computing infrastructure. You develop from the lowest levels of circuit design to large system design and see those systems all the way through to high volume manufacturing. Your work has the potential to shape the machinery that goes into our cutting-edge data centers affecting millions of AWS users.
About the team
In 2015 Annapurna Labs was acquired by Amazon Web Services (AWS). Since then we have accelerated its innovation and developed a number of products that benefit cloud customers including AWS Nitro technology Inferentia custom Machine Learning chips and AWS Graviton2 processors.
Annapurna Labs is a silicon/system and software organization that is delivering all the chips used by AWS customers. Today this includes: Graviton driving innovation for general purpose compute; Nitro driving networking and storage scale security and Hypervisor offload and Machine Learning (ML) Trainium and Inferentia that are enabling customers to train and run GenAI applications permanently while keeping costs under control.
