Full job description
Role Title: App Security Expert
Role Type: Contractor
Location: Remote
micro1 is engaging App Security Experts to contribute to a customer’s dynamic project focused on real-world application security. In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required — your domain knowledge is what matters.
Scope of Work
- Design and implement small, purpose-built application fixtures with embedded security vulnerabilities or secure solutions, specifically addressing OWASP LLM risks such as Sensitive Information Disclosure and Excessive Agency.
- 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.
