Sr. Application Security Engineer

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 C, C++, Rust, and Java source code assessments. 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?

Primary responsibilities include:

Support 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 C, C++, Rust, and Java 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 C, C++, Rust, and Java code and common frameworks

Present findings to stakeholders, 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

Collaborate with team members and software-focused threat hunters to elevate team technical standards

What Skills and Knowledge Will You Bring?

Ideal candidates will have:

5+ years in application security or product security with a strong software development background

A proven track record translating complex findings into technical and executive-level debriefs; excellent written and verbal communication is essential

Experience delivering customer-facing or consulting-style engagements end-to-end, comfortable in a distributed remote organization

Proficiency in at least two of C, C++, Rust, and Java, having previously identified and explained vulnerabilities at the framework level, not just the application level

Proficiency in at least two of C, C++, Rust, and Java, with a strong understanding of vulnerabilities and secure coding methodologies

Strong knowledge of OWASP Top 10, CWE Top 25, and modern authentication infrastructure (SAML, OAuth, OIDC, JWT internals); experience driving an application through ASVS Level 4 verification is a plus

Hands-on experience authoring custom static-analysis rules and queries for modern SAST engines; familiarity with AI-assisted code review workflows and validating findings produced by automated and agentic analysis pipelines

Strong threat modeling experience throughout the secure SDLC

Fluency with Git-based source control and CI/CD pipelines, including build-pipeline security controls, runner hardening, and release-gate enforcement

Experience with AI-accelerated development or code scanning methodologies

Nice to have:

Working depth in Python (Django/Flask) and Node.js (Express) for cross-language reviews.

Reverse engineering of compiled C, C++, Rust, Java (IDA Pro, Binary Ninja, Ghidra).

OSWE, CSSLP, GWAPT, published CVEs, or conference talks.

Familiarity with SOC 2, ISO 27001, or FedRAMP control mapping.
