From building industry-leading products to cultivating an exceptional company culture, our core values guide everything we do. We’re looking for passionate individuals who thrive in collaborative environments and are eager to drive impact. If you’re excited about solving complex challenges in bold, innovative ways, we’d love to connect with you.
Join us as a Staff Infrastructure Engineer and play a crucial role in designing and building our data & caching infrastructure, serving hundreds of engineers in dozens of product/engineering teams at S1!
SentinelOne's vision of one autonomous cybersecurity platform depends on our ability to collect, store, and analyse data efficiently. If you are interested in building infrastructure for data platforms that run reliably with 99.99% uptime, can scale to over 9 Petabytes of data ingested every day (and 3+ Trillion events processed), and return queries with p95 latencies less than 5 seconds, you will love this opportunity.
What will you do?- Lead the design & operation, and own end-to-end platform experience of mission-critical distributed data services - incl. Kafka or Redis - running at massive scale across Kubernetes clusters (EKS, GKE) and multi-cloud environments
- Unlock complete cloud portability for SentinelOne’s services by building a highly automated, self-service infrastructure that can run seamlessly across AWS, GCP, and air-gapped on-prem environments
- Manage data infrastructure supporting 7+ PB/day ingestion, ensuring low-latency, high-throughput, and cost-effective operation at a global scale
- Consolidate and optimize multi-tenant Kafka clusters to reduce cost, improve resilience, and streamline operations
- Drive lifecycle automation for the owned distributed data services, using GitOps principles and tools (GitHub Actions, ArgoCD, Terraform), reducing operational toil and minimizing pager fatigue
- Define and implement standards for observability, HA, backup, and DR of workloads in Kubernetes
- Partner with FinOps and engineering stakeholders to continuously optimize performance, cost, and operational overhead across data platform components
- Multiple years of experience in infrastructure/platform engineering, with a proven track record of operating distributed systems at scale
- Deep hands-on experience with self-hosted Kafka and/or Redis running in Kubernetes, including performance tuning, scaling, partitioning, persistence, and operator-based lifecycle management
- Highly desired: Experience providing Database- or Messaging-as-a-Service (DBaaS/PaaS) for internal development teams or external customers
- Strong understanding of Kubernetes internals and best practices for managing both stateless and stateful workloads in production environments
- Exposure to multi-cloud environments with strong expertise in at least one major provider: AWS, GCP, or Azure
- Experience with IaC and GitOps practices and tools (Terraform, ArgoCD etc.), solid understanding of CI/CD pipelines and workflow automation (GitHub Actions, Argo Workflows, etc.)
- Familiarity with advanced deployment strategies (blue-green, canary, rolling)
- Strong scripting or development skills (e.g., Python, Go, or similar)
- Nice to have: Experience with other messaging systems or data stores (e.g. Cassandra, ClickHouse) and with Kubernetes administration
