Technical Leader Physical Design
Annapurna Labs Ltd. · Tel Aviv, Israel · Software Development
Full-timeLead
About the role
Annapurna Labs, an Amazon team, designs and delivers high-end, custom silicon at the heart of AWS. Our chips don't just support the cloud — they define it. From Trainium, the purpose-built ML accelerator driving the next wave of AI innovation, to Graviton, the Arm-based server processor redefining price-performance for compute workloads, to Nitro, the advanced network and cloud management controller that underpins every AWS instance — Annapurna's products set the standard for the industry.
Founded by industry veterans and operating as a fabless semiconductor company within AWS, Annapurna Labs combines the agility of a startup with the scale of the world's largest cloud provider. Our engineers work with cutting-edge technologies to innovate and shape the future of cloud computing- designing the leading-edge semiconductor products that power Amazon's infrastructure. Here, you'll experience a fast-paced environment with continuous learning opportunities and the chance to develop next-generation platforms.
Exciting opportunity to join Amazon in developing its next generation products for the cloud market.
We are looking for talented people to join us, as leaders in our excellent Physical Design team, adopting super advanced process nodes, mentoring team members, and further developing our implementation methodologies.

Work/Life Balance
We value work-life harmony. Achieving success at work should never come at the expense of sacrifices at home, which is why we strive for flexibility as part of our working culture. When we feel supported in the workplace and at home, there’s nothing we can’t achieve.
- Understanding the entire place and route flow (“RTL to GDS”)
- Very deep understanding of timing
- Process and technology (advanced nodes) oriented
- Leadership and mentoring skills
- Previous experience in high-speed designs, multi-voltage (low power) designs
Our inclusive culture empowers Amazonians to deliver the best results for our customers. If you have a disability and need a workplace accommodation or adjustment during the application and hiring process, including support for the interview or onboarding process, please visit https://amazon.jobs/content/en/how-we-hire/accommodations for more information.
