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 build the lightweight security components that power our Generative AI Security platform - the core sensors and enforcement mechanisms that operate across endpoints, browsers, and production workloads to deliver real-time, adaptive protection. But building the technology is only half the job. We're looking for an engineer who understands why we're building it: someone fluent in our product, our roadmap, and the real GenAI risks our customers face every day - and who treats a customer problem as their own until it's solved.
You'll own your work end-to-end, engage directly with the realities of how customers deploy and rely on our sensors, and diagnose and fix issues on the fly when it matters. You'll collaborate with expert engineers on high-impact GenAI security challenges while growing your expertise and your influence on where the product goes next.
What Will You Do?
Primary responsibilities include:
- Build and optimize sensor components for minimal system footprint - high performance, low resource consumption, and maximum reliability across diverse customer environments.
- Evolve our Agentic AI capabilities by helping design adaptive policy logic, improving decision engines, and expanding coverage across platforms - grounded in real customer use cases and roadmap priorities.
- Build endpoint and browser security components and integrate them into the platform for real-time GenAI threat detection and data protection (prompt injection, sensitive-data leakage, shadow AI, and more).
- Own customer-facing technical problems end-to-end - investigate production issues, reproduce and fix them quickly under real-world pressure, and follow through until the customer is unblocked.
- Translate business and roadmap context into engineering decisions - understand what customers need, where the product is heading, and why, so your technical choices move the business forward.
- Collaborate across security engineering, QA, product, and customer-facing teams to hit customer and business goals - not just ship code.
- Stay current with GenAI and platform security and fold relevant advances into our sensors, agents, and extensions.
What Skills and Knowledge Will You Bring?
Ideal candidates will have:
- At least 6 years of experience in Python, Node.js, or a comparable language
- Experience with macOS and Windows Endpoint Security
- Proficiency in OS architecture and internals
- Strong customer orientation - you take ownership of customer problems and can diagnose and fix issues on the fly in real-world conditions
- Business and product awareness - genuine interest in the roadmap, the market, and the customers we serve, and the judgment to weigh technical decisions against business impact
- Accountability and growth mindset - you own your outcomes, hold yourself to a high bar, and actively invest in your own and the team's growth
- Excellent problem-solving skills and attention to detail
- Proficiency in browser extension development (Chrome, Firefox, etc.) - Advantage
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.
