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 Senior Data Engineer, you will play a vital role in designing, building, and maintaining the data infrastructure that powers our cyber threat detection research (core and critical part of our product). This infrastructure will enable data scientists and security researchers to make sense of petabytes of data and uncover the threats that matter. You will collaborate closely with cross-functional teams across the company - data scientists, security researchers, product managers, and engineers - to deliver innovative data solutions that help us build best-in-class threat detection and protect our customers.

What will you do?

Primary responsibilities include:

Design, build, and maintain scalable data pipelines that process petabytes of security data (we ingest 5-10 petabytes daily) for research purposes.
Develop production-grade pipelines, applying software engineering best practices.
Operate big data infrastructure and cloud data warehouses with a focus on reliability and performance.
Partner with data scientists and security researchers to deliver impactful data solutions.
Ensure data quality, observability, and governance across the platform.

What Skills and Knowledge Will You Bring?

Ideal candidates will have:

4+ years of experience in data engineering, data architecture, and distributed systems
Proficiency in programming languages such as Python (that we use), Java, Scala, or similar.
Experience with cloud-based technologies such as AWS (our primary), GCP or Azure.
Experience with deploying big data technologies such as Apache Spark, Hadoop, Hive, IceBerg, Trino.
Familiarity with data warehousing concepts and technologies.
Experience with data visualization tools such as Tableau, PowerBI, Grafana or similar.
Strong problem-solving skills, with the ability to develop innovative solutions to complex problems.
Excellent communication skills, with the ability to clearly present and explain complex data and models to technical and non-technical stakeholders.
BS or higher degree in Computer Science, Software Engineering, Statistics, Mathematics, or related field. Additional or directly relevant experience will be considered in lieu of a degree.
Experience in leading cross-functional projects between R&D and product teams.

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.
