  • Own Enterprise Connectivity: Build and automate secure networking solutions, including VPC peering, PrivateLink, and dedicated interconnects for customer-managed environments.
  • Drive Reliability: Set and maintain strict SLOs. You'll optimize networking paths and resource allocation to ensure our real-time AI features hit their latency targets.
  • Champion GitOps: Manage our entire stack via Terraform/Pulumi; ensuring that "the code is the truth" across all environments.
  • Security & Compliance: Implement "security-by-design," focusing on encryption at rest/transit and identity management (SAML/SCIM) to meet SOC2 and HIPAA standards.

  • IaC Architect: Proven track record managing large-scale environments using Terraform, Pulumi, or other production-ready, battle-tested IaC tools with a focus on reusable, modular infrastructure.
  • Operational Mindset: Experience with modern observability (Datadog, OpenTelemetry) and a "you build it, you run it" mentality.
  • Communication: Ability to write clear technical specs for both internal teams and external customers.
Nice to Haves
  • AI/ML Infrastructure: Experience building or scaling infrastructure for AI/ML workloads, specifically high-throughput inference systems or GPU-accelerated computing.
