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 Staff Software Engineer you will be tasked to join our On Prem Team, building customer-facing security experiences. This role is focused on designing and building scalable web applications that help customers understand their security posture, investigate risks, and take action through a unified management console.

You will operate above the individual contributor line — helping define our frontend engineering standards, mentoring senior engineers, and driving architectural decisions that span multiple product areas. We are looking for someone who can take a feature from requirements through implementation and long‑term maintenance, while leading the evolution of frontend architecture, reusable components, and shared frontend foundations across the product.

What will you do?

Primary responsibilities include:

• Build and evolve modern, scalable frontend applications using React and related web technologies
• Own the implementation of new features, user journeys, and pages in a customer‑facing security product
• Define and drive frontend architecture standards across multiple teams, with a strong focus on maintainability, performance, and developer productivity
• Own the roadmap and evolution of the shared component library and common frontend infrastructure
• Set the technical direction for frontend engineering practices, tooling, and patterns across the organization
• Partner cross‑functionally with design systems, backend platform, and product teams to translate complex business requirements into robust technical implementations
• Mentor and uplevel senior engineers through code reviews, design reviews, and hands‑on collaboration
• Integrate frontend experiences with REST APIs and backend services, including data‑dense security dashboards, real‑time telemetry feeds, and large‑scale grid and table performance
• Improve and maintain existing systems while continuously introducing better patterns, tooling, and technologies from the frontend ecosystem

What Skills and Knowledge Should You Bring?

Ideal candidates will have:

• Strong hands‑on experience in frontend development with a track record of building production‑grade web applications at scale
• Deep understanding of JavaScript, including the DOM, the JavaScript object model, and modern ECMAScript features
• Strong proficiency with React and a thorough understanding of its core principles
• Strong experience with TypeScript, component‑driven development, and building reusable UI patterns
• Demonstrated experience owning or significantly contributing to a shared component library or design system
• Experience integrating and working with REST APIs in complex product environments, including real‑time data, high‑frequency updates, and large datasets
• Strong understanding of HTML5, CSS, and modern browser‑based application development
• Familiarity with modern front‑end build pipelines and tools such as Webpack, NPM, and related tooling
• Ability to understand complex product and business requirements and translate them into clean technical solutions
• Strong understanding of code organization, shared state patterns, and frontend maintainability at scale
• Excellent communication, collaboration, and problem‑solving skills, including the ability to influence technical direction across teams

Bonus

• Experience contributing to open source projects
• Familiarity with coding agents and AI‑assisted developer tools such as Claude Code, Codex, or similar systems
• Experience with Node.js fundamentals or broader full‑stack exposure
• Strong product sense and a good eye for building superior user experience, particularly in security, observability, or data‑rich product domains
• Experience with agile development processes

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. If you want to build where innovation and impact move together, this is that place.
