About the role

Our Purpose

At SentinelOne, we are driven by a clear purpose: to give the advantage to those who secure our future. As AI reshapes how organizations build, operate, and innovate, the responsibility to protect them becomes more critical than ever. When you join SentinelOne, your work helps protect global enterprises, critical infrastructure, and the technologies shaping tomorrow. 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 Staff Supply Chain & Build-System Security Engineer, you will be tasked with becoming the trusted advisor customers call when malicious packages hit their build, or when a self-replicating worm crosses their CI/CD trust boundary. You'll work directly on top of the output of our agentic code scanning pipeline, validate supply-chain signals with human judgment, run reachability analyses, and harden the pipelines that ship our customers code into production.

What Will You Do?

Primary responsibilities include:

Lead Wayfinder Frontier AI Services customer engagements focused on software supply chain risk end-to-end — scope, deliver, and present findings to customer engineering and security leadership.
Review and triage supply chain findings from our agentic code scanning pipeline, validate true positives, eliminate noise, prioritize by real exploitability in the customer's environment, and ensure every finding that reaches the customer is a decision they can act on.
Investigate malicious-package incidents: triage suspected compromise, reverse engineer obfuscated install scripts (bun_environment.js-class), identify blast radius, and build customer deliverables.
Build dependency-graphs and reachability analyses across npm, PyPI, Maven, NuGet, Go modules, and Rust crates, document and prioritize findings.
Build and review SBOMs and AIBOM artifacts.
Deliver recommendations on hardening of customer CI/CD pipelines; GitHub Actions, Pinning, OIDC, Trusted Publisher migration, Harden-Runner deployment, runner identity scoping.
Cover client-side supply chain risk in customer engagements.

What Skills And Knowledge Will You Bring?

Ideal candidates will have:

7+ years in security with a strong concentration in software supply chain, build systems, or product security, plus a credible development background.
Proven track record translating complex findings into technical and executive-level debriefs. Excellent written and verbal communication is essential.
Deep npm internals fluency, publish flow, registry mechanics, Trusted Publisher and OIDC for publishing, plus working depth across PyPI, Maven Central, and NuGet.
Hands-on dependency analysis and reachability-based prioritization across multiple languages.
Working knowledge of SBOMs, build provenance, and artifact signing, including SLSA, in-toto, and Sigstore, and how to enforce them in a real pipeline.
Experience hardening build environments, git actions, runner isolation, and locked-down secrets handling.
Hands-on malicious-package triage and static reverse engineering of obfuscated JavaScript and Python.
Client-side supply-chain investigation experience (Magecart-class, CDN compromise, browser-bundle dependency confusion).
Experience with AI accelerated development / supply chain scanning methodologies.
