Senior Software Engineer - Java

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.

The Analyst Experience Features team builds and operates the systems that power our dashboard and visualization layer — the tools analysts use to investigate threats, surface trends and make sense of enormous volumes of data everyday. We own both the frontend and backend services behind those experiences, along with systems that integrate into our Singularity Data Lake product. Our work is exacting and consequential: fast, reliable systems that put the right data in front of analysts at the right time.

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
