Senior Chip Design Engineer , Graviton

Annapurna Labs is a fabless semiconductor company founded by industry veterans. We develop leading-edge products on state-of-the-art process technologies, and we're looking for talented engineers to help us build a semiconductor platform based on a revolutionary architecture.

You'll help develop state-of-the-art products within a disruptive system architecture, working on the technologies that power the world's largest cloud provider in a dynamic, open and fast-paced environment. AWS provides a highly reliable, scalable, low-cost cloud infrastructure platform that powers hundreds of thousands of businesses in 190 countries.

AWS Graviton is a family of processors designed to deliver the best price performance for cloud workloads running in Amazon Elastic Compute Cloud (Amazon EC2). Graviton is designed in-house. It has reshaped what EC2 offers AWS customers and has become their preferred choice for cloud compute.

You'll join the Chip Design team on the Graviton product line. The team defines the product's features and owns their architecture and development. We work closely with product definition, pre- and post-silicon validation, physical design, software and other teams across the full chip development cycle, from idea to mass production. Your design will ship in Graviton products deployed in AWS data centers worldwide, so your work will have large-scale impact.

At Annapurna Labs, you'll play a key role in developing the next generation of semiconductor platforms for the world's largest cloud infrastructure, and in shaping the future of cloud computing.

Key job responsibilities

Act as the technical lead for a major SoC domain across its full lifecycle, from feature definition through tape-out and silicon bring-up

Work with Product Definition and Architecture to turn product requirements into feature specifications for your domain

Lead micro-architecture definition and own power, performance and area trade-offs, working with Physical Design and Software

Drive RTL design in Verilog/SystemVerilog and lead design reviews for the domain

Define and execute IP integration strategies

Set verification priorities with the Verification and Emulation teams, and lead system-level and post-silicon debug for your domain

Carry design learnings into the next Graviton generations, and improve design methodology and flows

Mentor and technically guide engineers working in your domain, raising the technical bar of the team

About the team

Annapurna Labs started in 2011, as a fabless chip start-up, focused on bringing innovation to the fast-growing cloud infrastructure. Four years after its inception, Annapurna Labs was acquired by Amazon Web Services (AWS). Since then, we have accelerated innovation and developed a number of products that benefit cloud customers, including AWS Nitro technology, AWS Graviton processors, AWS ML Inferentia & Trainium and more. Although Annapurna Labs is a small company, it is significant for AWS, with a reputation of being the key ingredient in the "secret sauce" behind its success. The Annapurna Labs team is responsible for building custom chips, accelerators, and software stacks that run on top of them, which gives us the possibility to optimize and improve our products in different layers more effectively.

We are a dynamic group of engineers dedicated to pushing the boundaries of semiconductor innovation. Our team combines the agility of a startup with the resources of Amazon Web Services, creating a unique environment where breakthrough technologies are born. We collaborate across disciplines, from product definition to silicon validation, ensuring each chip represents the pinnacle of performance and reliability.
