Senior Linux & Infrastructure IT Engineer

About The Role

We are a fast-growing semiconductor startup building next-generation silicon. Our design and verification pipelines rely on large-scale Linux compute infrastructure spanning AWS and on-prem environments.

We are seeking a senior, hands-on Cloud & Infrastructure IT Engineer to own the reliability, performance, and automation of our mission-critical EDA platforms. You will work directly with chip design teams to ensure our compute environments are fast, stable, secure, and ready to scale.

Requirements:

What You’ll Do

• Operate and scale hybrid AWS + on-prem Linux compute infrastructure for chip design and verification workloads.

• Own day-to-day reliability, performance tuning, capacity planning, and incident response.

• Build and maintain AWS environments using Terraform and Ansible.

• Automate provisioning of VPCs, IAM, EC2, FSx, EBS, S3, VPNs, and security controls.

• Tune Linux systems for CPU-, memory-, and I/O-intensive EDA workloads.

• Operate and optimize grid / job scheduling platforms such as Slurm, LSF, or Grid Engine.

• Design and manage high-throughput storage solutions for simulation pipelines.

• Develop automation and self-service tooling using Python and Bash.

• Implement observability and alerting using Prometheus and Grafana.

• Participate in on-call rotation and lead root-cause analysis for production incidents.
