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 Fullstack Engineer, you will be tasked with building security asset orchestration tools, internal systems, and AI-assisted workflows that reduce operational friction and improve global engineering efficiency. In this role, you will bridge the gap between frontend excellence and backend scalability, using modern AI-assisted development habits to deliver production-quality software. You will collaborate with mission-driven teams to simplify complex operations and enable the safe, reliable delivery of detection content across a globally distributed environment.

What Will You Do?

Primary responsibilities include:

Contribute across the stack, including frontend (cca 70-80% of your time using React/TypeScript), backend services (using Golang and/or Python), APIs, data flows, and integrations.

Help shape frontend architecture, reusable components, testing practices, and maintainability standards.

Design, operate, and troubleshoot scalable, secure, and reliable systems in a globally distributed environment.

Work with technologies such as AWS/GCP, databases, CI/CD systems, messaging systems, Kubernetes, and ArgoCD.

Own engineering projects end-to-end, from problem definition and technical design to implementation, rollout, and production support.

What Skills and Knowledge Will You Bring?

Ideal candidates will have:

Proven experience as a Full Stack Engineer building production web applications.

Strong frontend experience with React, HTML, CSS, and TypeScript, including the ability to review code and guide frontend quality standards.

Backend development experience with languages such as Golang or Python, RESTful APIs, and client-server architecture.

Hands-on experience using AI coding tools as part of real software development work, alongside the ability to critically evaluate and refine AI-generated outputs.

Solid understanding of cloud environments, distributed systems, CI/CD pipelines, Kubernetes, ArgoCD, and production operations.

Strong ownership mindset and the ability to drive projects end-to-end in environments with ambiguity.

Experience with UX, data visualization, or designing intuitive workflows for technical users is a plus.

Experience with security products, especially detection systems, is a plus.

Why SentinelOne?
