Physical Design Engineer - Static Timing Analysis, Annapurna Labs, Cloud Scale Machine Learning
Work on static timing analysis and hardware optimization for AWS Inferentia machine learning silicon.
About the role
As a Physical Design Engineer on the Cloud-Scale Machine Learning Acceleration team, you will be responsible for the design and optimization of hardware in AWS data centers, including machine learning inference silicon such as AWS Inferentia.
What you'll do
- Develop and maintain flows for block and full-chip level static timing analysis.
- Write, debug, and validate timing constraints for blocks and full-chip.
- Run static timing analysis and provide frequent feedback to team members and leads.
- Provide guidance on how to fix timing issues by generating ECOs and fixing constraint issues.
- Develop scripts to automate running timing analysis and generating reports.
- Collaborate with other physical design engineers as well as RTL and architecture teams.
What you'll need
- Experience in developing and maintaining flows for block and full-chip static timing analysis.
- Demonstrated ability to write, debug, and validate timing constraints.
- Hands-on experience generating ECOs and resolving constraint and timing closure issues.
- Experience with scripting to automate timing analysis runs and report generation.

How we counted: 713 open Physical Design (Physical Design) roles from 87 employers tracked in the SemiconductorJobs index, counted 11 Nov 2026. Specialty figures count only roles carrying this exact specialty label, so an employer's related work in neighbouring specialties is not included there, and is counted in the wider Physical Implementation family row. Days are counted from when our index first saw each posting, not from the employer's original posting date.
