Director, Enterprise Security - Business Information Security Officer (BISO)

The Experience
Enterprise Security is hiring a Director, Business Information Security Officer (BISO), also called a Security Partner. You are accountable for the security posture of major Enterprise Business Units (BUs) and serve as their primary link to the broader Security organization.
This is a senior technical leadership role. You read designs, understand the systems, and take clear positions on architecture, controls, and trade-offs with engineers, product leaders, and executives.
You lead a small team of Security Partners and are the trusted security go-to for your BU’s senior technical and business leaders.
AI tools help you scale analysis and drafting, so you can focus on judgment and influence.
This role is based in NYC, NY; SF, CA; Denver, CO; Indianapolis, IN; Dallas, TX; or McLean, VA and is eligible for a hybrid work arrangement.
What You’ll Actually Be Doing
Own the security relationship for your assigned BU. Represent the customer’s voice inside Enterprise Security and security’s voice inside the customer’s leadership.
Own the risk register. Set severity, prioritization, and buy-down sequencing, accounting for compensating controls. Route risk-acceptance decisions to the right executive owner.
Build resourced risk buy-down plans with named owners and dates, hold teams accountable, and escalate when progress stalls.
Lead security input on design reviews, threat models, and architecture decisions. Shape the software development lifecycle (SDLC), secure-by-design patterns, and platform guardrails early.
Deliver quarterly reviews, risk narratives, and posture metrics ready for Chief Information Security Officer (CISO), Chief Information Officer (CIO), and Board audiences.
Bring in security engineers, the Cyber Security Operations Center (CSOC), technical program managers, and other specialists at the right time to drive outcomes the enterprise adopts.
Track emerging risks in AI and machine learning (ML) systems, such as agentic architectures, prompt injection, and model and training-data governance. Turn them into concrete risk and control decisions.
Consider compliance and regulatory requirements (such as FedRAMP, Sarbanes-Oxley (SOX), and regional data-protection laws) into your risk view to drive security prioritization, partnering with Legal, Privacy, and Compliance.
Drive adoption of security tooling, telemetry, and automation so risk decisions rest on data.
Manage, coach, and grow Security Partner Leads and Senior Leads. Set the operating cadence and the bar for deliverables, and develop successors.
Use approved AI assistants to produce executive-quality analysis and drafts, and help your team do the same.
Partner with Enterprise Security leadership on cross-portfolio strategy and enterprise-wide programs.
