We are engaging App Security Experts to contribute to a customer’s dynamic project focused on real-world application security.

- Develop deterministic test cases and security-context manifests to robustly assess application security posture.

- Create detailed hidden answer keys to enable accurate AI or scanner evaluation of vulnerable versus secure code.

- Evaluate and iterate on pipeline methodologies to ensure synthetic tasks and fixtures are challenging yet realistic for AppSec assessment.

- Document technical insights and methodologies, ensuring clarity in written feedback and communication.

- Collaborate through clear and thorough written and verbal communication to share findings and review peer contributions.

- Engage with agent-based security architecture and contribute to continuous improvement of the evaluation pipeline.

Preferred Qualifications

- Extensive experience (ideally 5+ years) in application security, secure software development, or CyberSWE roles.

- Strong understanding of OSWE, LLM security, AI-powered static analysis (AI-SAST), and AppSec best practices.

- Proven track record designing or evaluating security architecture for traditional and agent-based applications.

- Expertise in building, securing, and testing application codebases, including identifying and remediating advanced vulnerabilities.

- Exceptional written and verbal communication skills, with a focus on precise technical documentation and collaborative feedback.

- Experience with synthetic security fixtures and deterministic testing approaches is highly desirable.

- Demonstrated ability to deliver thoughtful insights and actionable security recommendations in a remote contribution context.
