Job description

  • Provision and optimize GPU compute across AWS, Azure, GCP, and specialized providers (CoreWeave, Lambda Labs), including Kubernetes GPU orchestration and hardware evaluation (NVIDIA H100/B200, AMD MI300X, Intel Gaudi)
  • Design and maintain IaC foundations (Terraform, Pulumi, Helm) for agentic AI systems, including agent orchestration platforms, RAG stacks, vector databases, and model serving endpoints
  • Implement policy-as-code guardrails (OPA, Sentinel, Kyverno) for autonomous agent workloads
  • Design and enforce zero-trust architectures with network segmentation, IAM/RBAC least-privilege, and secrets management (Vault, AWS Secrets Manager)
  • Configure and manage Cloudflare (or equivalent) for DDoS protection, WAF, bot management, SSL/TLS termination, and Zero Trust access
  • Manage DNS security (DNSSEC, DMARC, SPF, DKIM), certificate lifecycle, and API security controls (mTLS, token management)
  • Lead vulnerability management, penetration testing coordination, and CIS benchmarking
  • Partner with customer success teams to assess, secure, and threat-model customer deployment environments
  • Build and maintain CI/CD pipelines (GitHub Actions, GitLab CI) with integrated security scanning (SAST, DAST, SCA, container scanning)
  • Deploy and manage Kubernetes clusters across cloud and on-prem with security-hardened, GPU-enabled configurations
  • Implement observability (Prometheus, Grafana, Splunk, Datadog) and SIEM integrations
  • Lead incident response and drive compliance (SOC 2, ISO 27001, HIPAA, FedRAMP) through audit automation

Requirements

  • Proven expertise with Terraform/Pulumi, IaC, policy-as-code, and scripting (Python, Bash, PowerShell)
  • Hands-on GPU compute provisioning across major cloud and specialized providers
  • Experience with Cloudflare or equivalent CDN/WAF/DDoS platforms for perimeter security and Zero Trust
  • Strong background in AWS, Azure, GCP, and on-prem infrastructure with secure architecture focus
  • Proficiency in Kubernetes and Docker, including container security, GPU scheduling, and runtime protection
  • Deep understanding of network security, zero-trust principles, IAM/RBAC, and secrets management
  • CI/CD experience with integrated security scanning
  • Ability to conduct security assessments, threat modeling, and work directly with customers
