Senior Software Engineer - Java

We're looking for a Senior Software Engineer who thrives on solving hard problems, takes ownership seriously and brings both technical depth and intellectual curiosity.

Java is our primary language, but we're a polyglot team — we also work in Python, Go and other technologies.

We value engineers who are genuinely excited to pick up new tools and master them.

What Will You Do?

Primary responsibilities include :

• Designing and building distributed backend services that are reliable, performant, and secure — primarily in Java, with Python, Go and other technologies in the mix
• Going deep on hard engineering problems: understanding our data pipelines, troubleshooting distributed systems, latency optimization, improving failure modes
• Contributing meaningfully to design discussions — not just implementing what's handed to you but helping shape what we build and how
• Reviewing your teammates' code thoughtfully and having your own reviewed with the same rigor
• Participating in on-call rotations, investigating production issues methodically, writing RCAs and closing the loop with improvements that prevent recurrence
• Keeping your knowledge sharp and sharing what you learn — new technologies, better patterns and tools
• Our stack: Java (primary), Python, Go, Kotlin, Node.js — AWS & GCP, Kubernetes, Helm, Docker, Kafka, Redis, Jenkins, GitHub. We dogfood our own products and are vocal customers of them!

What Skills and Knowledge Will You Bring?

Ideal candidates will have

• 5+ years of engineering experience with a solid computer science foundation
• Strong Java proficiency (3–5 years hands-on) and comfort reading and writing Python
• Real experience building and operating distributed systems in production
• Fluency with containerization and cloud infrastructure (Docker, Kubernetes, Helm, AWS or GCP)
• Familiarity with CI/CD pipelines (Jenkins or GitHub Actions) and cloud data stores (S3, DynamoDB, Redis, RDBMS)
• A polyglot mindset — you're not precious about languages or technology and you pick up new ones quickly
• The habit of writing code that's concise, readable, and easy for the next engineer to reason about
• Strong communication instincts — you ask good questions early, surface concerns before they become problems and give feedback that makes designs better
• A track record for being someone your teammates genuinely enjoy working with — collaborative, low-ego and generous with your time and knowledge

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.

We invest in our Sentinels with comprehensive, competitive benefits designed to support you and your family:
