Staff Full Stack Engineer - Collection Engineering

What are we looking for?

We are building SentinelOne’s next-generation cloud-based security platform, and we are looking for an exceptional full-stack software engineer with expertise in Frontend development, an engineer who is excited about creating seamless user experiences and providing real business value, loves to take an active part, and can quickly dive into complex, large-scale environments.

What will you do?

• Our Collection Engineering team leads projects that directly impact the company's bottom line - we handle all data collection aspects from the SentinelOne agents (hundreds of billions of events daily), including EDR telemetry, XDR telemetry, forensic data collection, and script orchestration / Remote Operations. Our initiatives start from concepts and evolve into products deployed across millions of endpoints and servers.
• We’re a multidisciplinary team that comprises experts in backend, frontend, and endpoint technologies (Windows, Linux, macOS), enabling us to independently ideate, develop, and deliver solutions at scale.
• As a Staff Full-Stack Engineer, you’ll own both the UI/UX development (React, TypeScript) and contribute to backend development of our platform (Python and/or Golang). You’ll play a key role in shaping the architecture, design, and delivery of new modules within our next-generation security platform. Partnering closely with product managers and designers, you’ll work across multiple strategic product lines - making a direct, visible impact on mission-critical company initiatives.

What skills & knowledge should you bring?

• 6+ years of full-stack development experience, with strong expertise in modern front-end frameworks - React, TypeScript, Playwright.
• Proven experience in backend development (preferably Python and/or Go), including cloud-native architectures, data pipelines, and databases (SQL & NoSQL).
• Strong capability to design a solution according to product requirements, collaborate with PMs and UX Designers.
• Experience with developing unit/component tests as part of the development process.
• Strong communication skills, with a track record of thriving in hybrid/remote teams and leading cross-functional initiatives.
• Hands-on knowledge of Docker, Kubernetes, and cloud platforms (AWS, GCP, or equivalent).
• Angular experience is nice to have (in the past S1 used Angular/TS, and while you'll develop new solutions in React/TS, you may occasionally interact with some older pieces of codebase).
