About the Role

The Senior Principal Security Engineer is the strategic "Front Door" and primary technical contact for our Enterprise Security organization. This is a high-visibility, individual contributor role designed for an experienced authority who can bridge the gap between high-level security strategy and hands-on technical execution. They will be the primary interface between Enterprise Security, broader Technology teams, and specialized Cybersecurity units, ensuring that our initiatives are not only technically sound but also seamlessly integrated across the organization. As the "second in command" to leadership, they will provide the technical connective tissue that ensures our security posture is proactive, scalable, and aligned with the speed of the business!

In this role, you will:

• Act as the Strategic Interface by serving as the primary point of awareness for all technical inquiries, project intakes, and multi-functional collaborations involving Enterprise Security.

• Mentor and Influence by providing deep technical mentorship to engineers across the team while influencing senior partners on critical security investments and architectural pivots.

• Bridge Silos and partner with Infrastructure, Engineering, and specialized Cyber teams (e.g., SOC, GRC, AppSec) to ensure unified execution of the security roadmap.

• Tackle "Impossible" Problems and be responsible for the most sophisticated, high-impact security challenges that require a "big picture" view of the entire technology stack.

• Advise Leadership by acting as a trusted technical advisor to the head of Enterprise Security, translating complex technical risks into actionable business strategies.

About You

This is the ideal role for a multidisciplinary security veteran that has spent years in the trenches but has evolved into a strategic problem solver. They won't just find holes in a system; they build the roadmap to fix them at scale. Are you comfortable in the "gray space" between departments and do you possess the emotional intelligence to lead through influence rather than authority?

• The "Front Door" Mentality: Consistent record of leading complex multi-functional relationships and serving as a liaison between technical and non-technical teams.

• Strategic Execution: Experience developing and driving security strategies quickly and accurately.

• Security Engineering Mastery: Expert-level understanding of secure SDLC,
