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.
At Prompt Security, our mission is to empower organizations to safely harness the transformative power of Generative AI. As a one-stop security platform, we provide visibility, governance, and real-time protection against all Generative AI concerns, enabling organizations to innovate and prosper in the age of AI without compromising on security.
As a Staff Endpoint Software Engineer, you'll design and build the low-level security sensors and enforcement engines that sit at the heart of our Generative AI Security platform — running deep inside endpoints, browsers, and production workloads to detect and stop threats in real time. You'll own critical architecture decisions, work hands-on with OS internals (kernel-level hooks, system calls, process/network monitoring), and set the technical bar for how we build secure, lightweight agents at scale. This is a high-ownership role for engineers who love working close to the metal and want their code protecting real enterprise environments from day one.
What Will You Do?
- Architect and continuously optimize sensor components for minimal system footprint, high performance, low resource consumption, and maximum reliability.
- Drive the technical evolution of our AI Security Posture Management (Agentic) engine — designing adaptive policy logic, improving decision engines, and expanding platform coverage.
- Build and own endpoint security solutions (macOS & Windows), integrating deeply with OS-level APIs for real-time threat detection and data protection.
- Set technical direction and mentor engineers on best practices for building secure, high-performance, low-level system components.
- Partner closely with security researchers, QA, and product teams to translate emerging threats into shipped protection.
- Stay ahead of the latest developments in Generative AI security and OS-level threats, bringing new techniques into our agents and extensions.
What Skills and Knowledge Will You Bring?
- 6+ years of experience in Python, Node.js, or a comparable language, with deep hands-on work at the OS/systems level
- Strong experience with macOS and/or Windows Endpoint Security frameworks (e.g., EndpointSecurity.framework, ETW, minifilter/kernel drivers)
- Deep understanding of OS architecture and internals (processes, system calls, memory, file system, networking stack)
- Track record of owning complex, low-level systems from design through production at scale
- Excellent problem-solving skills, strong technical judgment, and attention to detail
- Experience with browser extension development (Chrome, Firefox, etc.) — Advantage
Why us?
- 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.
