About the job

Requirements
  • Strong application security or product security fundamentals and hands-on experience with vulnerability management.
  • Understanding of common vulnerability classes and exploitation techniques across web applications, application programming interfaces, authentication systems, cloud services, containers, and software supply chains.
  • Ability to read and reason about code and work effectively with software engineers on practical remediation.
  • Experience with vulnerability scanning and application security technologies such as static application security testing, software composition analysis, dynamic application security testing, secrets scanning, container scanning, or cloud security posture management.
  • Understanding of vulnerability prioritization concepts including Common Vulnerability Scoring System, exploitability, asset criticality, internet exposure, compensating controls, and threat intelligence.
  • Ability to investigate security findings manually rather than relying exclusively on scanner output.
  • Ability to automate security workflows using Python, Go, or similar scripting or programming languages.
  • Experience integrating security tooling into continuous integration and continuous delivery and modern software development workflows.
  • Comfort working with Linux, Git, containers, and cloud environments.
  • Ability to communicate security risk clearly to security specialists and engineering teams.
  • An automation-first mindset focused on scalable solutions instead of manual processes.
Responsibilities
  • Own and continuously improve vulnerability management across applications, software dependencies, containers, operating systems, cloud infrastructure, and externally exposed services.

  • Analyze vulnerabilities beyond scanner severity by considering exploitability, exposure, affected assets, available mitigations, and business impact.
  • Partner directly with engineering teams to triage findings, determine appropriate remediation, and drive vulnerabilities to closure within risk-based service-level agreements.
  • Build automation for vulnerability ingestion, deduplication, enrichment, prioritization, assignment, remediation tracking, and reporting.
  • Identify systemic vulnerability patterns and work with engineering teams to address root causes rather than repeatedly fixing individual findings.
  • Operate and improve application security capabilities including static application security testing, software composition analysis, secrets detection, container scanning, infrastructure scanning, and external attack-surface monitoring.
  • Validate security findings through technical investigation and hands-on testing, distinguishing exploitable vulnerabilities from false positives and low-risk findings.
  • Perform targeted application security reviews and testing for high-risk services and features.
  • Help integrate security controls into continuous integration and continuous delivery and developer workflows while minimizing unnecessary friction for engineering teams.
  • Develop metrics and reporting that provide visibility into vulnerability exposure, remediation performance, recurring vulnerability classes, and security risk.
  • Evaluate and integrate new security technologies as software and infrastructure environments evolve.
  • Partner with security and engineering teams on incident response when vulnerabilities are actively exploited or require urgent remediation.
Desired Qualifications
  • Experience in application security or security engineering.
