Staff Software Engineer

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 Staff Software Engineer you will be tasked to join on Prem Team.We are building and scaling SentinelOne's self-hosted (On-Prem) console, and we're looking for a Staff backend software engineer to provide technical leadership for the On-Prem team. As our new colleague, you should be excited about setting technical direction for systems that customers run in their own environments — from air-gapped data centers to private clouds. You should love taking an active role, be comfortable diving into complex, large-scale distributed systems, and enjoy owning the architecture, reliability, upgradeability, and operability of software that ships outside of SentinelOne's own infrastructure. As a Staff engineer, you will influence technical strategy across multiple teams and mentor engineers at all levels. What will you do? Primary responsibilities include:

• Set technical direction — Define the architecture and technical roadmap for the On-Prem console, aligning multiple squads of backend and frontend engineers around a coherent long-term vision.
• Drive complex initiatives end-to-end — Lead the most ambiguous, cross-cutting projects from problem framing through production, in self-hosted, constrained, air-gapped, and on-prem environments.
• Own the platform's architecture — Make foundational design decisions across the On-Prem console, choosing patterns and technologies for scale, reliability, upgradeability, and performance, and establishing the standards others build on.
• Own operability and lifecycle at scale — Shape packaging, deployment, patching, and upgrade strategy (e.g., OS upgrades, infrastructure components) that keep self-hosted customers secure and current.
• Multiply the team — Mentor and grow engineers, raise the engineering bar through design and code reviews, and serve as a force multiplier across the organization.
• See your impact — Your work directly improves how customers deploy, operate, and trust SentinelOne in their own environments, making it a visible part of key company initiatives. What skills & knowledge should you bring? Ideal candidates will have: Core Engineering
• 8+ years' backend-development experience, including a track record of technical leadership on large-scale systems.
• Proficiency in at least one of the following programming languages: Go, Python.
• Strong foundation in data structures, algorithms, and system design.
• Experience working with both RDBMS and NoSQL databases.
• Solid experience with unit and integration testing practices. Distributed Systems & Architecture
• Proven experience designing distributed systems — partitioning, consistency, and availability trade-offs.
• Proven experience architecting high-performance, microservices-based backend systems at scale.
• Hands-on with event-driven architecture and messaging platforms such as Kafka.
• Experience with high-scale API design, database design and sharding, and resilience patterns (e.g., circuit breakers).
• Deep understanding of operating systems and networking fundamentals. Cloud & Infrastructure
• Hands-on experience with at least one public cloud (AWS, GCP, or Azure).
• Experience with Docker and Docker Compose. Leadership & Soft Skills
• Strong ownership mindset — takes accountability for outcomes, not just tasks, from design through production and incident resolution.
• Proven cross-team influence — drives alignment and technical decisions without formal authority.
• Track record of mentoring engineers and contributing to their career growth.
• Comfortable with ambiguity — breaks down unclear problems and delivers under uncertainty.
• Excellent communication skills — translates technical complexity into business context and leads projects in a hybrid and/or remote team. Bonus
• Open-source contributions.
• Experience working with AI coding agents / agentic development workflows.
• Experience architecting software for on-prem, self-hosted, or air-gapped deployments.
• Hands-on experience with the Kafka ecosystem (Kafka Pub/Sub, Kafka Connect, etc.). 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.
