Qualification
Required
5+ years in infrastructure, DevOps, or SRE roles with increasing scope and ownership
Deep Google Cloud Platform experience, specifically with Cloud Run, VPC networking, IAM, and at least one managed database service
Strong Terraform skills in production — you've authored and maintained multi-environment, modular Terraform codebases, not just run applies
Hands-on cloud security experience: network security design (firewall rules, private networking, VPC peering), IAM policy architecture, secrets management, and vulnerability assessment
GitHub Actions proficiency — you've built and maintained CI/CD pipelines for containerized applications deploying to cloud infrastructure
Experience operating distributed systems that process high message or event volumes with strict latency and reliability requirements
Strong Linux fundamentals, networking knowledge (DNS, TLS, load balancing), and comfort debugging production issues across the stack
Security-first mindset — you think about attack surfaces, least privilege, encryption in transit and at rest, and incident response as part of every design decision
Comfort with on-call ownership and incident response in a small-team environment
Preferred
Experience with Spanner, Pub/Sub, Memorystore for Redis, Cloud Tasks, or Cloud Armor specifically
Background in messaging or telecom infrastructure — carrier API integrations, throughput management, rate limiting at scale
Experience with TypeScript/Node.js application ecosystems (you don't need to be a full-stack developer, but understanding the runtime helps)
Monorepo CI/CD experience — managing builds, tests, and deployments across multiple services in a single repository
Familiarity with compliance frameworks relevant to communications platforms (TCPA, SOC 2, carrier security requirements)
Experience as the sole or primary infrastructure engineer at a growing company — you've owned it end-to-end
Certifications: Google Cloud Professional Cloud Security Engineer or Professional Cloud Architect (valued but not required)
