  • Identify and help remediate common vulnerability classes across services and APIs (e.g., auth/authz, injection, data exposure, logic flaws).
  • Triage and support remediation of vulnerabilities identified through SAST/DAST tools, internal testing, or third-party findings.
  • Conduct security testing and validation, including targeted manual testing for high-risk areas.
  • Help improve secure development practices by creating reusable guidance, checklists, and secure patterns for engineering teams.
  • Contribute to security tooling and automation that improves coverage, reduces false positives, and streamlines security reviews.
  • Assist with product security incidents by supporting investigation, impact analysis, and follow-up remediation.
  • Communicate security risks clearly and pragmatically, helping teams prioritize effectively and ship safely.
  • Document learnings and contribute to evolving product security processes and standards.

Should have:

  • Experience performing security reviews, threat modeling, or secure architecture assessments for software systems.
  • Familiarity with security testing tools and practices (SAST/DAST, dependency scanning, fuzzing, manual testing).
  • Comfort reading and reviewing production code in at least one language (e.g., Python, Go, Java, JavaScript/TypeScript).
  • Exposure to automated or AI-assisted security tools or workflows, and interest in applying them to improve developer experience and security outcomes.
  • Ability to work cross-functionally with engineering teams and communicate findings in a constructive, actionable way.
  • Proven ability to drive remediation efforts and follow through on risk reduction outcomes.

Bonus / Nice-to-have:

  • Experience with cloud-native architectures (AWS/GCP/Azure), microservices, Kubernetes, service-to-service authentication, and secrets management.
  • Experience tuning security tools to reduce noise and improve signal (e.g., improving rules, baselines, or pipelines).
  • Familiarity with secure SDLC practices and security champions programs.
  • Exposure to bug bounty / vulnerability disclosure or working with external researchers.
  • Experience improving internal security automation or developer workflows (including using AI-assisted tooling).
