About The Position

Cerebras Systems is seeking a Senior Cloud Infrastructure Engineer to design, build, and operate the AWS infrastructure that powers its products and platform. This high-ownership, hands-on role sits at the intersection of infrastructure engineering and reliability. The engineer will architect scalable cloud systems, drive infrastructure-as-code practices, and partner with engineering teams to keep production fast, resilient, and secure as the company scales.

Requirements

• At least 8 years of experience in cloud infrastructure, SRE, or DevOps roles, with a strong software engineering foundation.
• Deep, hands-on AWS expertise, including the ability to architect complex multi-region, multi-account environments; AWS Solutions Architect Professional certification or equivalent practical depth is required.
• Expert-level Terraform skills and experience with Atlantis or similar GitOps workflows for infrastructure.
• Strong programming skills in Python, Go, or a similar language, including writing production-grade automation.
• Proven Kubernetes experience, preferably with EKS, including cluster lifecycle, networking, and workload reliability.
• Deep understanding of AWS networking, including VPC design, peering, Transit Gateway, Direct Connect, security groups, and NACLs.
• Experience with AWS IAM at scale, including role design, permission boundaries, OIDC federation, and least-privilege enforcement.
• Hands-on experience with AI coding tools and deploying AI-assisted automation for triage, incident response, or operational workflows.
• Strong incident command skills, including ownership of production outages end-to-end and writing postmortems.

Nice To Haves

• Experience with AWS cost optimization at scale, including Savings Plans, Reserved Instances, and Spot orchestration.
• Familiarity with cloud compliance frameworks such as SOC 2 and ISO 27001.
• Experience in GPU/ML infrastructure or high-performance computing workloads on AWS.
• A track record of running on-call rotations, defining SLOs, and improving operational maturity in a fast-moving environment.
• Experience supporting highly technical engineering populations where uptime and speed both matter.

Responsibilities

• Architect and operate core AWS infrastructure, including VPCs, EKS/ECS, IAM, networking, and data services.
• Own cloud workload reliability by defining SLOs, error budgets, and runbooks; lead incident response and durable root-cause remediation.
• Build and maintain infrastructure-as-code with Terraform and GitOps pipelines, eliminating manual provisioning.
• Design and implement multi-account AWS organization strategies using AWS Organizations, Control Tower, and SCPs for security and cost governance.
• Instrument cloud infrastructure with metrics, tracing, alerting, and cost visibility using tools such as Prometheus, Grafana, Datadog, or CloudWatch.
• Automate provisioning, scaling, patching, and lifecycle management to reduce toil.
• Partner with security, networking, and platform teams on cloud security architecture, identity federation, and network reliability.
• Evaluate and adopt AWS-native and third-party tools to improve developer experience and infrastructure efficiency.

Benefits

• Job stability with startup vitality.
• A simple, non-corporate work culture that respects individual beliefs.
