• Define, maintain, and enforce secure coding standards, guidelines, and reusable security patterns across development teams.

Development Security Operations (DevSecOps):

• Collaborate with development teams to identify gaps and harden CI/CD pipelines.
• Automate service management processes to improve response time and consistency.
• Establish and manage continuous security testing protocols within development workflows.

Vulnerability Management & Remediation:

• Conduct vulnerability assessments, triage and prioritize findings from scans, pen tests, and bug bounty programs.
• Work directly with engineering teams to ensure timely and effective vulnerability remediation.
• Lead root cause analysis and support incident response for application-layer security issues.
• Support incident response and root cause analysis for application-level security incidents.

System Performance and Security:

• Monitor system performance proactively, identify bottlenecks, and optimize configurations to improve scalability and efficiency.
• Configure and manage secure, role-based access controls, permission schemes, and page-level restrictions to protect sensitive data.
• Troubleshoot and resolve system issues to minimize downtime and ensure system reliability.

Security Champion & Developer Enablement:

• Serve as a hands-on security advisor to developers by offering training, guidance, and support on secure software development practices.
• Build and lead the Application Security Champions program to increase security awareness and ownership across engineering teams.

Leadership & Mentorship (Team Lead Focus):

• Mentor junior AppSec engineers and foster professional growth through coaching and knowledge sharing.
• Provide technical leadership and represent Application Security in security and engineering forums.
• Align security initiatives and roadmap priorities with broader engineering and business objectives.

Requirements and Skills

• Broad Expertise: Deep understanding of the Secure Software Development Lifecycle (SSDLC), with experience embedding security practices throughout Agile and DevOps environments.
• Autonomous & Collaborative: Ready to take ownership of your role, with the ability to work independently and effectively with remote teams.
• Curiosity & Investigative Mindset: Naturally curious with a strong investigative mindset, always eager to dig deeper into potential issues to identify the best outcome.
• Proactive Problem Solver: Capable of anticipating and addressing issues before they escalate.

Mandatory Requirement

We are looking for individuals who:

• Are available for full-time engagement.
