Senior Software Development Engineer - Data Security and Protection

About the Role As a P4 Senior Software Engineer, you will be a technical leader within the Security Platform organization. Your primary focus will be designing next-generation authorization frameworks, fine-grained access control systems, and distributed data security models that operate at a massive scale. You will not only write critical path code but also mentor junior engineers and influence the architectural roadmap for Workday’s global security infrastructure Key Responsibilities Architecture & Leadership: Lead the architectural design and implementation of highly available, low-latency authorization and access control services. Data Security: Define and implement robust data security boundaries, zero-trust architectures, and policy enforcement points across distributed systems. Technical Excellence: Drive best practices for code quality, security compliance, multi-tenancy isolation, and system performance optimizations. Mentorship: Guide, mentor, and unblock P3 and associate engineers on the team, fostering a culture of continuous learning and technical rigor. Cross-Functional Impact: Partner with security architects, compliance teams, and broad engineering organizations to seamlessly integrate authorization patterns across all Workday applications.
