The posting

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 Front-End Engineer, you will lead the design, build, and testing of SentinelOne's next-generation security orchestration and automation (SOAR) solution, a brand-new product offering built to extend the value of our cybersecurity platform. You will bring deep front-end and back-end expertise to drive this product from technical design through delivery, integrating it with our existing platform and collaborating closely with product, security, and other engineering teams. This is an opportunity to leverage modern technologies and help revolutionize how we defend against threats.

What Will You Do?

Primary responsibilities include:

  • Lead the design, development, and testing of SentinelOne's next generation security orchestration and automation (SOAR) tools, taking features from technical design through delivery with minimal guidance.
  • Integrate the SOAR solution with our existing product offering to extend the value of SentinelOne's cybersecurity platform, working through moderately complex technical challenges independently.
  • Collaborate closely with cross functional teams, including product, security, and other engineering teams, acting as a technical resource for the SOAR product area.
  • Work across the full stack, including React, TypeScript, Python (FastAPI with SQLModel), and NodeJS for the front end and services layer, Codemirror and Reactflow for the product's workflow building experience, and PostgreSQL, Docker, Kubernetes, Redis, AWS, and GCP for the underlying infrastructure.

What skills and knowledge should you bring?

Ideal candidates will have:

  • 6 or more years of professional full stack or front end engineering experience
  • Extensive coding experience in TypeScript using React, with the depth to independently lead design and implementation of complex front end systems.
  • Previous coding experience building backend APIs in Python - advantage.
  • Ability to mentor and act as a technical resource for colleagues with less experience.
  • Experience with Codemirror or Reactflow is preferred.

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.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
