About the Role

Aion Silicon is seeking a Senior EDA & HPC Infrastructure Engineer to own and manage the platforms powering their engineering workloads. This hands-on role requires deep expertise in Linux-based EDA and HPC environments, combined with strong AWS cloud engineering experience, to ensure the stability, performance, and continuous improvement of critical engineering infrastructure.

Responsibilities

• Own and maintain AWS-based engineering infrastructure across a multi-account, multi-VPC environment.
• Operate, optimize, and troubleshoot cloud environments supporting engineering workloads.
• Support cloud-based job scheduling using technologies like AWS ParallelCluster and SLURM.
• Balance platform performance, capacity, and cost.
• Maintain and extend Infrastructure as Code and automation for secure, repeatable builds.
• Own, operate, and continuously improve the Linux-based EDA and HPC compute farm.
• Manage license servers, grid services, production job scheduling, and shared storage.
• Optimize job throughput, queue behavior, license availability, and storage performance in collaboration with engineering teams.
• Manage EDA tooling and licensing arrangements with vendors.
• Provide clear visibility of tool availability and license utilization.
• Diagnose and resolve networking issues across on-premises and cloud environments.
• Work across multi-VLAN, multi-account, and multi-VPC infrastructure.
• Apply security, identity, and compliance best practices.
• Support the wider IT team with service issues and infrastructure incidents.
• Cross-train colleagues in AWS and cloud-native ways of working.
• Help build shared ownership of the platform and reduce single points of knowledge.

Requirements

• Substantial experience administering production Linux-based EDA compute platforms within a semiconductor or comparable engineering environment.
• Hands-on responsibility for licensing, job scheduling, and platform performance.
• Several years of practical AWS experience.
• Experience operating cloud-first infrastructure at scale, including migrated workloads.
• End-to-end EDA license management, including license servers, feature pools, denials, and utilization analysis.
• Experience with production job schedulers such as SLURM, LSF, or Grid Engine.
• Linux administration at scale using RHEL, Rocky Linux, or similar distributions.
• Experience with OS and kernel tuning, patching, and lifecycle management.
• Experience with storage performance tuning for I/O-intensive and metadata-heavy workloads, including NFS and cloud-native alternatives.
• Experience with production AWS environments using EC2, EBS, S3, VPC networking, and IAM.
• Experience working within a multi-account AWS estate.
• Experience with Infrastructure as Code using Terraform, CloudFormation, or similar technologies.
• Experience with automation using Python, Bash, or equivalent scripting languages.
• Experience with source-controlled infrastructure and automation integrated into CI pipelines.
• Experience with Layer 2 and Layer 3 network fault diagnosis across VLANs, routing, and switching.
• Experience with monitoring and alerting across compute, storage, and license utilization.
• Ability to communicate technical issues and trade-offs clearly to engineers, vendors, and senior stakeholders.
• Willingness to support both routine service requests and complex infrastructure incidents.
