What are we looking for?

We are building SentinelOne’s next-generation, cloud-based data pipeline and are looking for a strong backend software engineer. As our new colleague, you should be excited about building systems from scratch, love to take an active role, and be able to quickly dive into complex, large-scale environments and lead them.

By joining our team, you will, among other products, help develop the following products:

• Network Discovery: A product that delivers full visibility into every device on a corporate network. Customers can manage any asset, including those not yet protected or supported by SentinelOne, thanks to machine learning that automatically identifies all IoT devices.
• Vulnerability Management: A platform module that enables customers to analyze and prioritize the vulnerabilities detected by our cybersecurity solutions on their endpoints.

What will you do?

• Own features end-to-end - Join a cross-disciplinary squad of backend and frontend engineers working alongside Windows, Linux, and macOS endpoint specialists - taking ideas from whiteboard to production.
• Build customer-facing security insights - Design, implement, test, and deploy backend services that turn raw cybersecurity events into clear, actionable information.
• Shape our platform’s architecture - Lead the design of new modules across several strategic product lines, choosing patterns and technologies for scale, reliability, and performance.
• See your impact - Your work directly improves how customers understand risk and respond, making it a visible part of key company initiatives.

• Proficiency in at least one of the following programming languages: Go (cca 70% of development) or Java. Python is a plus.
