Job description

Position: Application Security Engineer (Senior AppSec)

Location: Remote

Duration: 6-12+ Months Contract

Role Overview

We are seeking experienced Senior Application Security Engineers to join our team and play a critical role in validating AI‑generated vulnerability findings and translating them into actionable technical remediation. This position requires strong expertise in application and product security, combined with a deep understanding of how vulnerabilities map to code and how developers remediate them in production environments. The ideal candidate will have a background as a software engineer who transitioned into AppSec, bringing both security insight and practical development knowledge.

Key Responsibilities

  • Validate AI‑generated vulnerability findings (e.g., from Anthropic’s Mythos) and assess exploitability, severity, and business impact.

  • Trace vulnerabilities to their technical root cause at the code level.

  • Collaborate with development teams to design and implement secure remediation strategies.

  • Conduct secure code reviews, threat modeling, and vulnerability assessments.

  • Define and enforce secure SDLC practices across product teams.

  • Provide guidance on API security, OWASP Top 10 risks, and secure design principles.

  • Partner with product owners and engineering teams to ensure vulnerabilities are remediated effectively and deployed safely.

  • Document findings, remediation steps, and best practices to strengthen organizational security posture.

Required Skills

  • Strong background in Application Security / Product Security.

  • Hands‑on experience with OWASP Top 10, SAST, vulnerability assessment, secure SDLC, threat modeling, code review, API security.

  • Ability to validate findings, assess severity, and trace vulnerabilities to root cause.

  • Experience working directly with developers to remediate vulnerabilities.

  • Strong communication skills to bridge security and engineering teams.

Ideal Profile

  • A software engineer turned AppSec professional — someone who understands both the security problem and how developers actually fix it.

  • Proven ability to work across multiple product teams, enabling secure development practices.

  • Experience with modern CI/CD pipelines and integrating security tooling into developer workflows.
