- Build and test incident-response playbooks for high-risk scenarios.
- Lead vulnerability identification, validation, risk-based prioritization, remediation coordination, retesting, and closure.
- Coordinate security assessments, penetration testing, and adversary simulation.

### Automation and Continuous Improvement
- Build scripts, integrations, and automated workflows using Python, PowerShell, and APIs.
- Establish security metrics covering detection, remediation, and incident trends.
- Own and improve firewall policies, VPN and secure connectivity, segmentation, traffic filtering, and monitoring.
- Review systems, integrations, and architecture changes to define risk-based security requirements.
- Evaluate AI-assisted security workflows with safeguards for sensitive data and human validation.

### Collaboration and Leadership

- Mentor junior team members and develop repeatable team practices.
- Support audits and assessments and maintain policies and standards aligned with NIST, ISO 27001, SOC 2, and financial-services requirements.

## Requirements
- 5+ years of experience in security engineering, threat hunting, detection engineering, security operations, incident response, or infrastructure security.
- Proven ability to independently lead complex technical projects end-to-end.
- Hands-on experience with SIEM, EDR/XDR, firewalls, IDS/IPS, WAF, vulnerability-management, email-security, and identity-security platforms.
- Strong knowledge of attacker TTPs, incident-response processes, and MITRE ATT&CK.
- Solid understanding of network security fundamentals, including segmentation, firewalls, VPNs, DNS, HTTP/TLS, and access control.
- Experience securing cloud and enterprise environments; AWS, Microsoft 365, Entra ID, Windows, macOS, and Linux experience preferred.
- Scripting and automation ability with Python, PowerShell, Bash, and REST APIs.
