• Conduct threat modeling, vulnerability assessments and security code reviews across different platforms, ensuring security is embedded at every stage of the development lifecycle
• Provide mentorship, guidance, and training on security best practices and secure development processes to engineering teams working in mixed cloud and operating systems environments
• Perform vendor security reviews to assess third-party security practices and ensure compliance with standards
• Integration of security scanning tools (SAST, DAST, etc.) into CI/CD pipelines and runtime environments to ensure continuous security monitoring and threat detection across Cloud - AWS, Azure, and on-prem systems
• Proactively identify security risks and develop strategies for risk mitigation

Your present skillset

• At least 7 years of experience working as a Security Architect with significant practical experience in securing software development and infrastructure at scale
• Proven record of accomplishment in secure coding practices and development experience in development languages such as Python, C++, Rust, Go and Kotlin/Java
• Strong technical background in software development, system architecture and security tools
• Strong understanding of security principles, techniques and technologies related to software and product security, cloud platforms and business applications. Knowledge of low-latency financial systems would be an advantage
• Experience working with and securing both Windows and Linux-based systems
• Extensive experience with one or more cloud platforms such as AWS, Microsoft Azure and Alibaba Cloud used in a hybrid environment
• In-depth knowledge of threat modeling, risk assessment and development of mitigation strategies for large-scale, complex systems in a fast-paced environment
• Experience integrating security scanning tools into CI/CD pipelines and runtime environments
• Experience conducting vendor security reviews and managing third-party security assessments
• Excellent leadership, problem-solving, communication and adaptability skills, suited for a senior-level position in a fast-paced environment
