Head of Security

Job title: Head of Security

About the Role Moment is hiring a Head of Security to own the security function end-to-end. As the most senior security leader, you'll drive strategy, build the program, hire the team, interface with customer security organizations, and own security outcomes.

What You'll Do

• DRI the security program. Application security, cloud infrastructure security, identity and access management, vulnerability management, detection, and incident response.
• Set the standards and run the operations.
• Scale security programs. Be comfortable working with top-tier RIAs, broker-dealers, and global bank security teams.
• Own compliance and regulatory posture. SOC 2, plus regulatory baselines relevant to broker-dealers and institutional financial infrastructure. Run audits, manage the Trust Center, and partner with Legal and Compliance as we expand into new asset classes and jurisdictions.
• Be the calm in incidents. When something breaks, you run the room, make the call, communicate to clients, and write the postmortem.

What We're Looking For

• Deep technical skills. You can read code, reason about modern cloud architectures (AWS, Kubernetes), threat-model real systems, and ship security tooling yourself when the moment calls for it.
• High-stakes experience: Experience in running a security program at a fintech, trading firm, or financial infrastructure company, somewhere where the stakes were real and the regulatory bar was high.
• Confidence in front of senior client security teams: You've cleared enterprise security reviews at major institutions and feel very comfortable getting into specifics around our technical architecture level and security program.
• A builder of the function mentality. This is a 0-to-1 leadership role, where you’re expected to contribute as a senior IC to begin.
• Even better if you have prior experience at a core fintech infrastructure provider.
• SOC 2 Type 2 audit experience as the lead.
• Background in security engineering: CSPM, IAM, AppSec, detection engineering, or incident response with real shipped work, not just oversight.

Compensation & Benefits

• Base salary: $275K to $325K. Equity: aggressive initial grant + annual performance-based bonuses.
• Our West Village Office with a terrace; 5x a week in office.
• Free lunch and dinner.
• $150 monthly gym stipend.
• Health, dental, and vision coverage. 100% company reimbursement.
