• Perform in-depth analysis of OWASP Top 10 and advanced vulnerability classes including business logic flaws, broken access control, and insecure deserialization.

• Design, code, and deploy AI-powered automation tools and security scripts that enhance vulnerability detection, threat triage, and testing efficiency at scale.

• Write clean, maintainable code to build internal security tooling, integrations, and AI-assisted workflows that reduce manual effort across the Security Engineering Team.

• Conduct threat modeling for complex, high-risk systems and new product initiatives, recommending security architecture improvements.

• Serve as a security advisor and informal leader to development and product teams - driving security-by-design principles and secure coding best practices.

• Mentor and coach associate security engineers - conducting knowledge-sharing sessions, reviewing their work, and supporting their professional development.

• Produce clear, risk-rated vulnerability reports with actionable remediation guidance for both technical and non-technical audiences.

• Contribute to the development and maintenance of application security policies, standards, playbooks, and training materials.

• Stay ahead of evolving threats and vulnerabilities in the financial services and fintech space, translating intelligence into actionable controls.

Required Qualifications:

• 3-6 years of hands-on experience in application security, with demonstrated ownership of security assessments and remediation cycles.

• Deep familiarity with OWASP Top 10, OWASP Testing Guide (OWTG), and OWASP Application Security Verification Standard (ASVS).

• Proven experience conducting Web application, API, AI/ML, Mobile and Desktop penetration testing using tools such as Burp Suite Pro, OWASP ZAP, or Metasploit.

• Demonstrated ability to code and build AI-powered security automation tools - including scripts or integrations using Python, JavaScript, or similar languages.

• Experience working with AI/ML APIs or LLM-based tools to automate security workflows such as vulnerability analysis, report generation, or threat detection.

• Demonstrated leadership skills - including the ability to guide peers, facilitate technical discussions, and influence security outcomes across teams.

• Excellent communication skills - able to articulate risk clearly to both technical teams and business stakeholders.

• Has background in threat modeling and mobile penetration testing.

Preferred Qualifications:

• Industry certifications such as OSCP, GWAPT, eWPT, CSSLP, CISSP, or equivalent.

• Experience in banking, insurance, or financial services with working knowledge of PCI-DSS, BSP regulations, ISO 27001, or SOC 2.

• Cloud security experience on AWS, Azure, or GCP - including knowledge of cloud-native appsec controls.

• Experience with mobile application security testing on iOS and Android platforms.

• Proficiency in threat modeling using STRIDE, PASTA, or similar methodologies for complex, multi-tier systems.

• Exposure to red team exercises or bug bounty programs.
