Key Responsibilities

- AppSec & Offensive Testing: Perform dynamic and static application security testing (SAST/DAST/SCA), red team exercises, penetration testing, and manual code reviews on live applications and APIs to surface business logic flaws and complex vulnerabilities.
- Hands-on Vulnerability Remediation: Prioritize risks using CVSS and business context, then directly execute code-level patches and infrastructure configuration fixes across .NET, Java, and React stacks in live production and legacy environments.
- AppSec Tooling Management: Configure, manage, and optimize enterprise security scanners—including Wiz, Snyk, Qualys, Burp Suite Enterprise/Pro, and OWASP ZAP—to minimize noise and maximize actionable findings.
- DevSecOps & Pipeline Automation: Embed automated SAST/SCA scanning, dynamic secret management, and compliance gates directly into GitHub Actions CI/CD pipelines to enforce "shift-left" security.
- Governance & Threat Modeling: Conduct architecture security reviews and threat modeling based on OWASP SAMM principles to align hybrid environments with compliance standards (e.g., PCI-DSS, HIPAA, GDPR).
- Cloud & Infrastructure Hardening: Secure and harden hybrid architecture spanning AWS cloud environments, containerized workloads, and on-premise infrastructure.

Must-Have Skills

- Offensive & Defensive AppSec: Proven expertise in penetration testing, red teaming, manual code reviews, and dynamic analysis using tools like Burp Suite Professional and OWASP ZAP.
- AppSec Tooling Expertise:



Hands-on experience configuring and operating Wiz, Snyk, Qualys, SonarQube, and automated DAST platforms.
- Code-Level Remediation: Ability to read, refactor, and patch vulnerable code across .NET, Java, and React stacks to remediate OWASP Top 10 vulnerabilities.
- DevSecOps & Secrets Management: Experience embedding security into GitHub Actions pipelines and implementing dynamic secrets management (AWS KMS, HashiCorp Vault, IAM).
- Security Frameworks: Strong command of OWASP Top 10, OWASP SAMM, threat modeling methodologies, and Software Bill of Materials (SBOM) tracking.

- AWS & Hybrid Security: Demonstrated track record securing AWS cloud environments, IAM policies, network controls, and hybrid/on-prem infrastructure.

Nice-to-Have Skills

- Industry Certifications: Relevant security certifications such as OSCP, OSWE, CISSP, GWAPT, or AWS Certified Security – Specialty.
- Healthcare & Payment Compliance: Deep familiarity navigating regulatory frameworks like HIPAA, HITRUST, and PCI-DSS within healthcare or fin-tech environments.

- Legacy Systems Refactoring: Practical experience untangling and securing legacy monolithic architectures without causing operational downtime.

- Advanced Container Security: Experience securing containerized ecosystems (Docker, Kubernetes/EKS) and runtime security monitoring.

Nice-to-have:

- AI Tooling Proficiency: Leverage one or more AI tools to optimize and augment day-to-day work, including drafting, analysis, research, or process automation. Provide recommendations on effective AI use and identify opportunities to streamline workflows.

- Familiarity with cloud-based infrastructure and services (e.g., AWS and GCP), Docker, and the Git version control system
- Familiarity with consuming and integrating APIs in a reliable and secure manner.
