Staff Software Engineer (Java)- Endpoint Protection

About the role

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 Staff Backend Engineer, you will work on a high‑throughput, highly available agent configuration platform for exclusions, policies, and security controls, safely delivering customer intent from the console to millions of agents worldwide and serving as the foundation for all console‑driven agent configuration. You will also be responsible for configuration processing and delivery pipelines that turn user and system changes into optimized payloads consumed by agents at a massive scale. As part of SentinelOne's main product line - Endpoint Protection , we secure tens of millions of devices across the globe running all kinds of OS (Windows, Linux, macOS) and process billions of security events every day. You'll be joining a team with a significant impact on how our customers' environments (including 4 of Fortune 10 companies, hundreds of Global 2000, and public sector) are protected, how they interact with agents via configuration, gain visibility into their security posture, and understand the risks and act upon them. What Will You Do? Primary responsibilities include : Design, develop, implement, test, document, and operate large‑scale, high‑volume, and low‑latency backend platform services - that turn customer intent (for example, exclusions, policies, and security controls) into effective configuration on every protected endpoint. Improve reliability, scalability, and observability of configuration management, ensuring configuration changes can be processed at scale, meet latency and throughput objectives, and be traced end‑to‑end across systems. Translate business and functional requirements into robust, scalable, and operable configuration solutions that fit within our overall data and control‑plane architecture. Maintain application stability and data integrity by defining and monitoring key metrics and SLOs (for example, configuration delivery latency, error rates, configuration coverage) and continuously improving the codebase and architecture. Evolve existing configuration services and platforms through regular refactoring and decomposition while delivering incremental customer value. Collaborate closely with other engineering, product, and customer‑facing teams to design configuration models and APIs that are flexible enough for new security use cases while safe and operable in production. Continuously learn and adopt new technologies and architectural patterns that help us scale configuration management to hundreds of millions of configurations and requests per second while keeping the system observable and operable. Mentor and grow the engineering team, providing technical guidance, conducting design reviews, and fostering an environment of continuous learning and high-quality code standards. Your Toolkit: Our new components are primarily developed in Java, while our current backend uses Go and Python. Communication between microservices is facilitated using gRPC, REST, GraphQL APIs, and Kafka, depending on specific requirements. We use PostgreSQL and ClickHouse for efficient event and configuration state storage and retrieval at scale. Our services are deployed across multiple AWS/GCP regions with Kubernetes; among other tools, you'll also use Docker, GitHub, and ArgoCD. You'll have access to modern AI‑powered tools to accelerate development, deb
