Principal Infrastructure Architect – Cloud & SaaS Platforms

Role Summary We are a global leader in online protection, dedicated to making the digital world a safer place. We are seeking a highly experienced and hands-on Principal Infrastructure Architect with a deep background in large-scale multi-cloud environments (AWS, GCP, Azure) and modern SaaS delivery. This is a unique opportunity to lead the architectural evolution of our platform, driving a critical migration from legacy EC2 topologies to cloud-native EKS/Kubernetes clusters, and designing the backbone for our next-generation AI and real-time data services.

We highly value experience gained at FAANG or other leading Big Tech companies.

This is a Hybrid position located at either or San Jose or Newport Beach, CA offices. You will be required to be on-site 2 to 3 days per week. When you are not working on-site, you will be working from your home office. We are only considering candidates within a commutable distance to either San Jose or Newport Beach, CA offices and are not offering relocation assistance at this time Position Details

About the Role:

Cloud Native Strategy & Migration:
Lead the architectural design and execution of migrating legacy EC2-based workloads to Amazon EKS and Kubernetes. Define standards for multi-region availability, auto-scaling, and spot instance orchestration.

Advanced Traffic Management:
Architect and deploy high-performance API Gateways and specialized LLM Gateways to manage traffic for Generative AI workloads. Implement Service Mesh (e.g., Istio, Linkerd) for advanced traffic splitting, mTLS, and observability.

Real-Time Data

Infrastructure: Design robust infrastructure for diverse storage engines, including AWS-native databases (DynamoDB, Aurora), OLAP systems, and real-time databases like Aerospike and Druid to support sub-millisecond latency requirements.

Event-Driven Backbone:
Architect scalable Pub/Sub messaging systems (Kafka, SNS/SQS, Pulsar) to decouple microservices and enable event-driven architectures at internet scale.

Comprehensive Observability:
Define and implement a unified observability strategy based on Open Telemetry (OTLP) standards. Integrate platforms like Grafana, Datadog, and Graylog to provide "single pane of glass" visibility into logs, metrics, and traces.

Identity & Security Engineering:
Modernize Authentication and Authorization systems (OIDC, OAuth2, SPIFFE/SPIRE). Deploy and manage centralized Secret Stores (Hashi Corp Vault, AWS Secrets Manager), security gateways, and automated certificate management systems.

Infrastructure as Code (IaC):
Champion a "Git Ops" culture by treating infrastructure as software. Enforce best practices using Terraform, Crossplane, or Pulumi, ensuring all environments are reproducible and audit-compliant.

Technical Leadership:
Mentor senior infrastructure engineers, drive "Well-Architected" reviews, and collaborate with software teams to ensure infrastructure supports rapid product iteration.

About You:

10+ years of professional experience in infrastructure engineering and architecture, with a proven track record of managing large-scale cloud deployments in AWS (primary), GCP, or Azure.

Kubernetes Expert:
Deep, hands-on mastery of Kubernetes and EKS, including experience with custom controllers, operators, and migrating stateful/stateless workloads from VMs to containers.

Database Reliability:
Strong experience architecting infrastructure for high-scale data systems, specifically real-time stores (Aerospike, Redis) and analytics engines (Druid, Click House).Security & Compliance:
Extensive experience designing secure infrastructure, including implementation of Zero Trust networks, WAFs, and secret management systems. Familiarity with compliance standards (SOC2, PCI-DSS) is a plus.

Observability Stack:
