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.

SentinelOne recently launched Wayfinder Frontier AI Services — a new customer-facing offering that pairs frontier AI models with our most seasoned offensive and defensive experts. The service extends our Wayfinder portfolio (Threat Hunting, MDR Essentials, MDR Elite, Incident Readiness & Response) into proactive, AI-accelerated exposure management.

In this role, you'll do more than review code — you'll become the trusted advisor customers turn to on Go, Java, and C#-based source code assessment. You'll work directly on top of the output of our agentic code scanning pipeline, validate findings with human judgment, deliver results to diverse technical and leadership audiences, and shape the methodology that scales the practice.

What Will You Do?

• Lead Wayfinder Frontier AI Services customer engagements end-to-end, scope the work, deliver the technical findings, and present results to executive and technical stakeholders.

• Review and triage findings from our agentic code scanning pipeline against customer Go, Java, and C# codebases. Validate true positives, eliminate noise, and ensure every finding that reaches the customer is a decision they can act on.

• Conduct deep code review across Go, Java, and C# code and common frameworks.

• Present findings to stake holders, translate technical risk into business impact and map exposures into end-to-end exploitation chains..

• Author and maintain SAST rule packs that scale across the customer base, and partner with our AI/ML engineers to improve our agentic scanning engine.

• Provide expert remediation guidance to customer development teams and validate fixes through follow-up review.

• Work closely with our engineering teams to enhance our agentic code scanning pipeline, and reduce false positives.

• Mentor senior AppSec engineers and software-focused threat hunters to elevate team technical standards.

• Define and refine the service line’s core methodologies, engagement playbooks, and scoping templates.
