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 are seeking a seasoned technical leader who can navigate the inherent complexity of cloud resources discovery for thousands of customers of our fast-growing Cloud Security productline. As a Senior Engineer, you understand that onboarding is a high-stakes distributed systems problem. You will architect the engine that manages the initial “handshake” across a wide range of cloud portfolios—from single-account setups to vast enterprise organisations. Your challenge is to ensure this discovery process is fast, reliable, and scalable, regardless of whether we are connecting to established providers or expanding into new cloud environments.

In this role, your technical influence extends beyond the IDE. You will act as the technical bridge between Product Management and our DevOps/SRE partners. You understand that, at our scale, a small inefficiency in a discovery query can cause a database bottleneck. Consequently, you are someone who designs with “operational excellence” in mind — leveraging Terraform, Helm, and Kubernetes to build services that are as easy to monitor as they are to deploy. You take pride in mentoring less senior engineers, helping them master the art of writing maintainable code that survives the “wild west” of varied cloud configurations.

Beyond your backend expertise in Java, we need a strategist who can review our current onboarding flow and identify where we need to harden stability or refactor to support future growth. You are a “clean code” advocate who hates technical debt and loves building elegant solutions to complex integration problems. If you are passionate about building high-performance discovery systems in a fast-paced, product-driven environment, you’ll find a home here.

What will you do?

Contribute to the architecture, design, and implementation (mostly Java, occasional Go) of a complex, multi-cloud onboarding platform
Implement and integrate solutions across existing (AWS, GCP, Azure, etc.) and new cloud providers, utilizing Terraform, ArgoCD, Helm, and Kubernetes to deploy and manage global services.
Take the lead on making our architecture more modular and provider-agnostic, ensuring we can support new environments with minimal friction.
Build systems that serve thousands of enterprise and government clients, including 4 of the Fortune 10 - strengthening security across the world’s most complex cloud environments.
Work closely with product managers, designers, and SREs to deliver high-quality features that prioritize both functionality and system stability.
Proactively support the growth of the team by driving design discussions and providing constructive, high-quality feedback to mid-level and junior engineers.

What skills and knowledge should you bring?

Multiple years of experience in backend software engineering using Java; experience with Go would be an advantage.
Extensive experience with AWS, GCP, Azure, and/or other cloud platforms (and their respective security/API landscapes); and solid experience with Terraform and Kubernetes.
Experience with large-scale high-load distributed systems & performance.
A “security-first” mentality with a passion for building clean, maintainable, and highly observable systems.
