Principal Platform Infrastructure Engineer (SRE Enablement)

Menlo Security is the leader in Browser Security for human and agentic workforces. Our mission is to enable humans and agents to connect, communicate, and collaborate securely, without compromise. The Menlo Browser Security Platform protects organizations from cyberattacks by stopping threats across the web, documents, and email before they reach the user. With Menlo Agent Runtime Security (MARS), that protection now extends to the AI agents working alongside every employee. Menlo Security is trusted by major global businesses, including Fortune 500 companies and government agencies, to protect their most valuable asset, their data, and is backed by top-tier investors.

About the Role

Platform Infrastructure Engineering is responsible for building and operating Menlo Security's Infrastructure Platform. Together with the rest of our engineering teams, we enable our customers to connect to the Internet without compromise. Our environment provides services globally. We expect failure, build security in by design, create evolvable systems, and enable multi-tenancy across the infrastructure. Automation is an absolute for us.

We are committed to getting it done properly, the first time.

As a Platform Infrastructure Engineer, you'll join a group of experienced engineers who are part of a globally distributed team responsible for building and managing the company's core infrastructure services and maintaining our constantly growing platform. The team operates a sophisticated cloud-native infrastructure built on Google Kubernetes Engine and VMs spanning multiple environments globally from development to production. We manage infrastructure as code with Terraform and Spacelift orchestration, and deploy services using Helm charts. Our platform emphasizes security-first design, comprehensive observability, and multi-region resilience. Success in this role requires working with a vast VM fleet in AWS and GCP as well as Kubernetes, writing Infrastructure as Code, and a passion for automation and reliability engineering.

Responsibilities

• Architect and govern the design, deployment, and operation of high-scale, multi-region VM and Kubernetes infrastructure on GCP and AWS, ensuring maximum resilience and performance across all environments.

• Drive cross-functional technical alignment with Engineering, Product, Compliance, and Security teams, serving as the architectural consultant and leader for major initiatives involving capacity planning, disaster recovery, and cloud-native application design.

• Define and enforce organizational best practices and standards for Infrastructure as Code (IaC) using Terraform and Spacelift, ensuring consistency and security across all provisioned cloud resources (GCP/AWS).

• Design and manage complex, multi-layer configuration management and deployment workflows that optimize reliability and operational efficiency across the entire platform.
