## 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 Windows Low Level Engineer - Endpoint security, you will design and develop advanced security features for SentinelOne’s Windows endpoint protection platform, operating across both user-mode and kernel-mode environments. You will build and optimize mission-critical components including anti-tampering protections, network sensors, and agent infrastructure while solving complex performance and stability challenges at massive scale. By researching Windows internals and debugging deep system issues, you will collaborate with distributed engineering teams to deliver high-impact security capabilities protecting millions of devices worldwide.

We are seeking a highly skilled and experienced Software Engineer with a strong background in low-level C++ programming and a deep understanding of Windows OS, to help us in developing our Endpoint Protection product, the core part of our business, and to join one of our Platform group teams. (We're currently growing multiple teams and are open to new colleagues with a wide variety of backgrounds within Windows development!).

The Platform group teams are in charge of some of our most complex low-level areas, such as:

- Windows agent’s Anti-Tampering (self-protection from malware attempting to harm the agent), network sensors, device control, and other kernel-side features involving both research and development,
- usermode security & agent infrastructures - e.g. installers, logging, services such as communication layer & interfaces for our Windows agent, for improving the quality, performance & stability of the agent and making the user experience smoother.

By joining our group, you will collaborate with talented engineers who are leading a feature through the whole development lifecycle. Your work will have an impact on millions of endpoints in one of the mainstream areas of the[EPP/EDR agent of SentinelOne](https://s1.ai/endpoint) - a product recognized 5x-in-a-row as Gartner MQ Leader, scoring highly in many MITRE Att&ck assessments, valued by users in Gartner Peer Insights and more.

What will you do?

- As a new member of one of our distributed development teams, you will work in both user-mode & kernel-mode, and deal with a large variety of fields.
- You will have the chance to design, develop primarily in modern C++ (23), test and debug the most complicated real-world problems (often unseen before). In order to successfully deal with this challenge, you will continuously enrich your knowledge and experience with Windows OS internals & Kernel, Endpoint Protection, and Endpoint Detection & Response eco-system.
- Our teams design and execute significant new features, as well as rewrite and reimplement the existing ones from scratch. You will also deal with extraordinary performance & optimization challenges, given the scale of our cybersecurity SW (handling hundreds of billions of events every day).
- Your work will influence the security of tens of millions of Windows devices, that we protect at enterprise & government customers across the globe (incl. 4 of Fortune 10 and hundreds of Global 2000).
- You’ll also be encouraged to share knowledge within both Platform teams and the broader Windows group.

What skills & knowledge should you bring?

- Multiple years of experience as a software engineer in the area of lowlevel programming using modern C++ (or using C and a willingness to learn modern C++)
- Hands-on experience and in-depth understanding of Windows OS design & internals, Windows low-level development, with debugging of Windows applications and familiarity with related standard debugging and profiling tools
- Previous experience working on a production-grade product with a wide-scale deployment
- Great communication skills and the ability to work both independently and with peers from different time zones, problem-solving and out-of-the-box thinking
- Attention to detail and high coding standards
- An advantage: experience with Windows Kernel and Windows Drivers development, experience in security-oriented development, with reversing or malware analysis
