About The Position

Simile is seeking an Infrastructure Engineer who thrives on the complexity of modern deployment patterns. This role involves owning the infrastructure roadmap from design to operation, ensuring the platform is resilient, compliant, and ready for global scale. The Infrastructure team is responsible for building the foundational systems that allow AI agents to operate at scale with uncompromising security, working at the intersection of high-scale cloud networking, distributed systems, and enterprise-grade privacy. The team's work is organized into three core pillars: Cloud Foundation (managing multi-cloud footprint with a focus on high availability, cost-efficiency, and Infrastructure-as-Code), Enterprise Deployments (building "paved paths" for VPC peering, PrivateLink, and BYOC for large customers), and Platform & Reliability (developing CI/CD pipelines and observability stacks).

Requirements

• 5+ years of experience building production-grade infrastructure in a high-growth environment.
• Deep expertise in AWS is required; experience with GCP or Azure is a major plus.
• Deep understanding of DNS, Load Balancing, Service Meshes, and complex VPC routing.
• 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.
• Experience with modern observability (Datadog, OpenTelemetry) and a "you build it, you run it" mentality.
• Ability to write clear technical specs for both internal teams and external customers.

Nice To Haves

• Experience building or scaling infrastructure for AI/ML workloads, specifically high-throughput inference systems or GPU-accelerated computing.
• Strong K8s (EKS/GKE) experience, specifically around multi-tenant security and resource isolation.

Responsibilities

• Architect Multi-Cloud Environments: Design and scale multi-region architectures across AWS and GCP to support global data residency and failover requirements.
• Enable Engineering Velocity: Partner cross-functionally with Product Engineering, Research, and Security teams to build internal tooling and "paved paths" that accelerate development velocity and empower every engineer to ship with confidence.
• 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. Optimize networking paths and resource allocation to ensure real-time AI features hit their latency targets.
• Champion GitOps: Manage the 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.

Benefits

• Competitive compensation packages that include base salary, equity, and comprehensive benefits.
• Grants are available for eligible roles, subject to board approval.
• Comprehensive medical, dental, and vision coverage.
• Flexible time off policies to support work-life balance.
