About Betterment Betterment is a leading, technology-driven financial services company that offers investing, savings and retirement solutions for retail investors and investment advisors as well as financial wellness solutions, including a 401(k) for small and medium-sized businesses. Our team is passionate about our mission, to empower people to build wealth with confidence and ease. We're headquartered in NYC and offer hybrid NY-based positions (four days/week in-office, with no required office days during the summer and winter holidays). About the Role Betterment is hiring a Sr. Security Engineer, Corporate Information Security to be a principal member of the Workforce Security team. We're responsible for managing identity and logical access across the company, owning change management for the systems employees and contractors rely on every day, and operating the technologies that secure them: Okta, Google Workspace, Slack, Atlassian, Glean, Jamf, and the SaaS portfolio that surrounds them. As we extend centralized management to a small Windows and Linux footprint, you'll help shape how we do that securely from day one. This is a hands-on senior IC role focused on designing, implementing, and continuously improving identity architecture, privileged access controls, endpoint hardening standards, and our overall workforce security posture. You'll embed secure access patterns across SaaS, managed browser, mobile, and workstation environments partnering closely with other Security teams, IT, Legal, Compliance, and the business units we serve. In parallel, you'll partner with our AI Governance & enablement team to evaluate, enable, and secure the use of AI tools (ChatGPT, Claude, Glean Assistant, and the agentic tooling that's coming next) establishing practical guardrails that let employees move quickly without compromising data or systems. This role is based out of our NYC office. Below we've reflected the base salary range for this position.

Security Design: Lead initiatives across authentication, authorization, federation, and privileged access.
