About Us

At SentinelOne, we’re redefining cybersecurity by pushing the limits of what’s possible—leveraging AI-powered, data-driven innovation to stay ahead of tomorrow’s threats.

From building industry-leading products to cultivating an exceptional company culture, our core values guide everything we do. We’re looking for passionate individuals who thrive in collaborative environments and are eager to drive impact. If you’re excited about solving complex challenges in bold, innovative ways, we’d love to connect with you.

What are we looking for?

We're excited to expand our team with passionate and skilled backend engineers, who are interested in solving non-trivial scale and data problems with a unique blending of cloud, distributed systems, and software optimization techniques and services. The EventDB team is responsible for SentinelOne's highly scalable columnar database which ingests Petabytes of data & trillions of events per day. Born from our acquisition of Scalyr/DataSet in 2021, EventDB is not just a regular database; it is engineered to efficiently scale to exabytes, serving as a critical component in our security and data infrastructure.

We're seeking a seasoned colleague, able to lead features/epics, inspire others as a Staff Software Engineer, and lead technically. You will interact with engineers in and across the org, tech leads, architects, product management, sales, and marketing.

Because our team’s work is closely tied to the user’s experience of our platform, your work will have an outsized impact on the company, on future customer-facing features, and on how customers leverage our platform in order to protect their business. If you thrive in an environment where collaboration, creativity, and technical excellence are valued, we're looking for you!

You will be joining one of the fastest growing publicly-traded SaaS companies, with a mission of ‘Empowering the World to Run Securely’. Together through our SW, we will serve thousands of users from security teams at enterprise & government customers across the globe (incl. 4 of Fortune 10 and hundreds of Global 2000), and protect tens of millions of endpoints, clouds & identities.

Requirements

What Do You Bring to the Table?

We do not require a perfect match with everything below; however, the more this describes you, the better of a fit you will be for this role!

• Experience

  • Solid computer science/software engineering/similar background with multiple years of practical engineering experience.
  • Proven expertise in designing and operating distributed systems.

• Technical Mastery

  • Strong proficiency in Java (multiple years of hands-on experience).
  • You value elegant code that is concise and readable.
  • Have you used tools like Jenkins (or alternative), Helm, Docker? Do you have infrastructure experience with AWS, GCP, K8s, etc? Great, that helps!

• A Collaborative, Curious, and Practical Mindset

• If this sounds like you, we should talk:

  • You are excited about opportunities to serve as a mentor and to play a pivotal role in fostering both technical excellence and team unity.
  • You enjoy writing modern Java (we love lambdas) and prefer composition to inheritance.
  • You can identify relevant algorithms in the literature & bring them into production when they fit.
  • Your passion for understanding and solving complex engineering challenges is matched by your pragmatic approach to problem-solving.
  • You're comfortable weighing in on CAP theorem considerations, and are energized by selecting the data structure with the perfect trade-offs for a problem at hand.
  • You believe that honing ideas and technical designs with other engineers is crucial for achieving an optimal solution.
  • You’re looking for a challenge that doesn’t just require you to use technologies like Kafka and Cassandra, but requires you to rebuild them because they didn’t meet the project requirements.
  • Garbage collection doesn’t faze you because you know the JVM like the back of your hand. You can rattle off the available garbage collectors and their tuning parameters.
  • You value asking good questions, because you believe “a problem well-stated is half-solved.”
