Job description

Our Purpose

At SentinelOne, we are driven by a clear purpose: to give the advantage to those who secure our future. As AI reshapes how organizations build, operate, and innovate, the responsibility to protect them becomes more critical than ever. When you join SentinelOne, your work helps protect global enterprises, critical infrastructure, and the technologies shaping tomorrow. If you are motivated by meaningful challenges and want your impact to be real, measurable, and global, you will find purpose here.

About Us

SentinelOne is a company at the intersection of AI and security, pioneering a new operating model for cybersecurity. Our AI-native platform unifies protection across endpoint, cloud, identity, data, and AI systems to deliver autonomous detection and response with clarity and speed. By combining real-time analytics, intelligent automation, and a unified data foundation, we reduce noise, simplify complexity, and empower security teams to focus on what truly matters.

Our teams are builders, problem-solvers, and innovators committed to shaping the future of security. If you are excited to solve hard problems alongside talented, mission-driven people, we invite you to help us build a safer future for humanity.

What Are We Looking For?

We’re looking for people who are relentlessly curious and committed to continuous learning. AI is reshaping every function across our business, and we enable every team member, regardless of role or level, to build fluency in AI tools and concepts. Those who thrive here actively seek out new solutions, experiment thoughtfully, and apply what they learn to drive better, faster, smarter outcomes.

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-gap 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.
