As a Senior DevOps Engineer / Platform Engineer, you will be tasked with building, scaling, and optimizing SentinelOne's core data and caching infrastructure running at massive scale across Kubernetes clusters and multi-cloud environments. You will unlock complete cloud portability for applications and services while ensuring low-latency, high-throughput, and cost-effective operations. Your work will directly empower our autonomous cybersecurity platform to process petabytes of daily data with 99.99% uptime.

What will you do? 

Primary responsibilities include:

• Lead the design, operation, and end-to-end platform experience of mission-critical distributed data services, including Kafka or Redis, across Kubernetes clusters and multi-cloud environments.
• Unlock complete cloud portability for SentinelOne apps and services by building a highly automated, self-service infrastructure across AWS, GCP, and air-gapped on-prem environments.
• Manage and scale data infrastructure supporting petabytes/day ingestion to ensure low-latency, high-throughput, and cost-effective operations.
• Consolidate and optimize multi-tenant Kafka clusters to reduce cost, improve resilience, and streamline operations.
• Drive lifecycle automation for distributed data services using GitOps principles and tools like GitHub Actions, ArgoCD, and Terraform to minimize operational toil and pager burden.
• Define and implement standards for observability, high availability (HA), backup, and disaster recovery (DR) of workloads in Kubernetes.
• Partner with FinOps and engineering stakeholders to continuously optimize performance, cost, and operational overhead across data platform components.

What skills and knowledge should you bring?

Ideal candidates will have:

• Multiple years of experience in infrastructure, platform, or DevOps engineering with a proven track record of operating distributed systems at scale.
• Hands-on experience with self-hosted Kafka and/or Redis running in Kubernetes, including performance tuning, scaling, and operator-based lifecycle management.
• Strong understanding of Kubernetes internals and best practices for managing both stateless and stateful workloads in production or air-gapped deployments.
• Multi-cloud experience with production expertise in at least one major provider (AWS, GCP, or Azure).
• Solid experience with Infrastructure as Code (IaC) and GitOps practices using tools like Terraform, ArgoCD, and CI/CD workflow automation (GitHub Actions).
• Strong scripting or development skills in at least one mainstream language like Python, Go, or Ruby.

Why SentinelOne?

AI is redefining how the world operates and rewriting the rules of security in real time, and SentinelOne was built for this moment. From day one, we architected an AI-native platform designed to operate at machine speed, not as an add-on to legacy systems but as the foundation itself. If you want to build where innovation and impact move together, this is that place.
