- Develop proof-of-concept exploits and adversary emulation scenarios.

- Deploy and monitor honeypots/honeynets for threat detection and behavior analysis.

DevSecOps & Secure SDLC :

- Integrate security tools (SAST, DAST, SCA, IaC scanning) into CI/CD pipelines (GitHub Actions, Jenkins, GitLab CI/CD).

- Automate security testing and policy enforcement in the development lifecycle.

- Collaborate with DevOps and developers to implement secure coding practices and remediation workflows.

- Build custom scripts/tools for security automation (Python, Bash, PowerShell).

- Monitor and harden containerized and cloud-native infrastructure (Docker, Kubernetes, serverless).

- Support security gate controls and compliance checks across release pipelines.

Reporting, Documentation & Communication :

- Deliver detailed technical reports and executive summaries of findings.

- Present findings to cross-functional stakeholders including engineering and executive leadership.

- Provide actionable remediation guidance with risk prioritization.

- Develop technical documentation, threat playbooks, and attack narratives.

Leadership, Collaboration & Mentorship :

- Mentor junior penetration testers and review their assessments.

- Lead purple teaming exercises to bridge offensive and defensive capabilities.

- Collaborate with blue teams to enhance detection and response.

- Conduct knowledge sharing sessions and internal capability development.

- Stay current with threat landscape, tools, and techniques.

Required Qualifications :

Experience & Background :

- 8 - 10 years in cybersecurity with primary focus on penetration testing and red teaming.

- At least 2 years hands-on experience integrating security in CI/CD and DevSecOps environments.

- Proven leadership in complex offensive security engagements.

Technical Skills :
