Cloud Infrastructure Engineer

About the job

Cerebras Systems builds the world's largest AI chip, 56 times larger than GPUs. This architecture allows Cerebras to deliver industry-leading training and inference speeds; over 10 times faster than GPU-based hyperscale cloud inference services.

This order of magnitude increase in speed is transforming the user experience of AI applications, unlocking real-time iteration and increasing intelligence via additional agentic computation.

Cerebras works with the leading model labs, global enterprises, and cutting-edge AI-native startups. OpenAI recently announced a multi-year partnership https://openai.com/index/cerebras-partnership/ with Cerebras, to deploy 750 megawatts of scale, transforming key workloads with ultra high-speed inference.

THE ROLE

We are seeking a Senior Cloud Infrastructure Engineer to design, build, and operate the AWS infrastructure that powers Cerebras' products and platform. This is a high-ownership, hands-on role at the intersection of infrastructure engineering and reliability — you will architect scalable cloud systems, drive infrastructure-as-code practices, and partner with engineering teams to ensure our production environment is fast, resilient, and secure as we scale.

RESPONSIBILITIES

- Architect and operate core AWS infrastructure: VPCs, EKS/ECS, IAM, networking (Transit Gateway, Direct Connect, PrivateLink), and data services (RDS, S3, ElastiCache).

- Own the reliability posture of cloud workloads — define SLOs, error budgets, and runbooks; lead incident response and durable root cause remediation.

- Build and maintain infrastructure-as-code using Terraform and GitOps pipelines; eliminate manual provisioning entirely.

- Design and implement multi-account AWS organization strategies (AWS Organizations, Control Tower, SCPs) for security and cost governance.

- Instrument cloud infrastructure with comprehensive observability — metrics, tracing, alerting, and cost visibility using tools like Prometheus, Grafana, Datadog, or CloudWatch.

- Drive automation for provisioning, scaling, patching, and lifecycle management to eliminate 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 tooling to improve developer experience and infrastructure efficiency.

QUALIFICATIONS

- 8+ years of experience in cloud infrastructure, SRE, or DevOps roles with a strong software engineering foundation.

- Deep, hands-on AWS expertise — able to architect complex multi-region, multi-account environments from first principles. AWS Solutions Architect Professional or equivalent practical depth required.

- Expert-level Terraform; experience with Atlantis or similar GitOps workflows for infrastructure.

- Strong programming skills in Python, Go, or similar — comfortable writing production-grade automation, not just scripts.

- Proven experience with Kubernetes (EKS preferred) — cluster lifecycle, networking (CNI, service mesh), and workload reliability.

- Deep understanding of AWS networking: VPC design, peering, Transit Gateway, Direct Connect, security groups, and NACLs.

- Experience with AWS IAM at scale — 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 — you've owned production outages end-to-end and written the postmortems.

PREFERRED QUALIFICATIONS

- Experience with AWS cost optimization at scale (Savings Plans, Reserved Instances, Spot orchestration).

- Familiarity with compliance frameworks (SOC 2, ISO 27001) in a cloud context.

- Experience in GPU/ML infrastructure or high-performance compute workloads on AWS.

- Proven track record of running on-call rotations, defining SLOs, and driving operational maturity in a fast-moving environment.

- Experience supporting highly technical engineering populations where uptime and speed both matter.
