SUMMARY Platform Infrastructure Engineering builds and operates Menlo Security's Infrastructure Platform, enabling our customers to connect to the Internet without compromise. As a Platform Infrastructure Engineer, you'll join a globally distributed team of experienced engineers building and managing the company's core infrastructure services on a cloud-native platform built on Google Kubernetes Engine and VMs spanning multiple regions and environments. The team manages infrastructure as code with Terraform and Spacelift, deploys with Helm, and emphasizes security-first design, comprehensive observability, and multi-region resilience. The team also uses AI-assisted development and code-review tools, including Gemini Code Assist, as part of the standard engineering workflow, and this role is expected to use LLM-based tooling to build and troubleshoot infrastructure code efficiently. OUTCOMES & KPIS Key Outcome(s) Owned: - Reliable, secure, and scalable infrastructure across GCP and AWS supporting Menlo's platform globally. - Reduced operational toil and incident recurrence through automation and Infrastructure as Code practices. - Comprehensive, end-to-end observability framework providing deep platform visibility, proactive health monitoring, and accelerated incident detection and resolution. Success Metrics / KPIs: - Infrastructure uptime/availability across regions (e.g., 99.9%+) - Mean time to detect (MTTD) and mean time to resolve (MTTR) for incidents - Percentage of infrastructure changes deployed via IaC (Terraform) vs. manual changes - On-call incident volume and reduction in repeat/preventable incidents - Lead time for provisioning new infrastructure WHAT YOU'LL DO - Implement, deploy, and maintain VM and Kubernetes infrastructure on GCP and AWS across dozens of clusters spanning development, staging, and production environments in multiple regions - Build and maintain Infrastructure as Code using Terraform modules and Spacelift (or equivalent TACOS), provisioning networking, compute, storage, and security components, and implementing multi-layer configuration management workflows - Implement and maintain observability solutions using Grafana Cloud, Prometheus/Mimir, and OTel collectors, designing dashboards and alerting rules across all platform components - Manage certificate lifecycle, DNS automation, ingress controllers, and service mesh networking with Cilium - Partner with peers and across Engineering, Product, Compliance, and Security teams to align on requirements and consult on capacity planning, disaster recovery, and architectural decisions - Identify and eliminate toil through automation — writing scripts, building CI/CD pipelines, and using AI-assisted coding tools to move faster - Participate in a 24x7 on-call rotation as part of a globally distributed team, responding to incidents and driving post-incident reviews FUNCTIONAL COMPETENCIES Required: - Bachelor's degree in Computer Science, a related…
