• Contribute to Red Team operations or simulations, including scoping, execution support, and post-exercise analysis.
• Build and operate vulnerability communication processes that provide timely, actionable alerts on new threats.
• Perform continuous threat assessment by incorporating threat intelligence, emerging vulnerabilities, and attack trends into scanning coverage, notifications, and prioritization.
• Collaborate with other security sub-teams including detection/response, compliance, application security, and infrastructure to maintain consistent efforts and reduce duplication.
• Escalate critical or time-sensitive issues promptly and offer practical mitigation options.
• Document findings, produce metrics, and deliver regular risk summaries to leadership.

• Experience working directly with engineering teams to close findings.
• Scripting and automation experience using Python, Bash, PowerShell, or similar, including building internal tools.
• Strong understanding of networking fundamentals (TCP/IP, DNS, firewalls) and their relationship to vulnerability exposure.
• Reverse engineering or vulnerability development experience.
• Experience triaging or working reports from bug bounty platforms such as Bugcrowd or HackerOne.
• Hands‑on participation in Purple Team or Red Team exercises.
• OT Security experience.
• Experience with continuous threat assessment, threat intelligence, or risk‑based vulnerability prioritization.
• Experience developing internal security tools, dashboards, or automation pipelines with production‑quality code and integrations.
• Experience with web application testing frameworks and tools.
• Experience performing software code reviews for security issues.
• Experience improving developer experience for security tooling and processes.
• Knowledge of network segmentation principles and implementation.
• Experience with asset discovery or inventory processes.
• Experience building or operating emerging vulnerability notification or alerting workflows.
• Familiarity with AI/LLMs and MCPs.
• Familiarity with cloud environments (AWS, Azure, GCP) and their native security or vulnerability features.
• Experience with configuration management, patching, or infrastructure‑as‑code.
• Knowledge of threat modeling, risk scoring (for example, CVSS), and prioritization frameworks.
• Familiarity with enterprise security controls and best practices for Windows, Linux, and macOS.
• Strong communication skills, translating technical findings into business impact and clear remediation steps.
• Relevant certifications (for example, OSCP, GSEC, or equivalent) or demonstrated equivalent experience.
• Demonstrated problem‑solving skills, including ability to determine root causes quickly.
