[Hiring] Senior Software Engineer (Java) - Cloud Security @SentinelOne

What Are We Looking For

We are seeking a seasoned technical leader who can navigate the inherent complexity of cloud discovery for thousands of customers. 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 P2 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 and Go, 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 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 tens of thousands of users; 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?

• Experience: 5+ years of experience in backend software engineering.
• Multi-Cloud Expertise: Deep knowledge of at least two major cloud providers and their respective security/API landscapes.
• Technical Depth: Expert-level knowledge of Java and hands-on experience with Go in a production environment.
• Infrastructure as Code: Proven experience managing infrastructure using Terraform and orchestrating containers with Kubernetes.
• Mindset: A "security-first" mentality with a passion for building clean, maintainable, and highly observable systems.
