The role focuses on embedding security across the entire software development lifecycle, partnering closely with engineering teams to build secure, scalable, and resilient products. You will work on modern technologies, distributed architectures, and CI/CD ecosystems while driving security automation and risk-based decision-making. As part of a collaborative and experienced security team, you will have the opportunity to influence security strategy, improve developer experience, and directly contribute to customer trust and platform integrity. This position offers significant autonomy, global collaboration, and the chance to make a visible impact in a rapidly evolving technology landscape. Accountabilities Partner with engineering teams throughout the software development lifecycle to integrate security-by-design principles into products and services. Lead the implementation, optimization, and integration of application security tools, including SAST, DAST, SCA, and container security solutions within CI/CD pipelines. Drive vulnerability management initiatives by identifying, prioritizing, and coordinating remediation efforts across applications and software supply chains. Conduct secure architecture reviews, threat modeling exercises, and risk assessments for distributed, API-driven, and microservices-based systems. Support and coordinate application security incidents, collaborating with internal stakeholders to investigate, mitigate, and learn from security events. Contribute to security audits, customer assurance activities, compliance initiatives, and continuous improvement of security processes. Promote pragmatic and developer-friendly security practices while enabling teams to make informed, risk-based decisions. Help enhance the overall security posture of products and engineering processes through automation, guidance, and strategic security initiatives.
