Chief of Staff

Company Overview

An AI-native cybersecurity company replacing legacy tool sprawl and alert fatigue with autonomous agentic security for complex enterprise environments.

By pairing intelligent AI agents with deeply technical engineers, the company customizes its platform to fit each customer's unique systems and workflows - delivering actual outcomes rather than unmanageable alerts.

• Founders: Cybersecurity veterans with a track record of building and scaling companies valued at over $10 billion.
• Funding: Seed-funded by leading venture investors to rethink how security work gets done in the AI era.

The team is seeking an exceptionally high-caliber Chief of Staff to serve as a force multiplier for the founding team. Operating at the intersection of strategy, go-to-market, and core operations, you will lead high-priority strategic initiatives, optimize company-wide execution, and scale our operating model as we build next-generation frontier AI infrastructure.

• Strategic Execution: Drive high-impact cross-functional initiatives across research, GTM, data acquisition, and product.
• Executive Force Multiplier: Partner directly with the founders to prioritize focus, run executive workflows, and turn strategic intent into operational reality.
• Operations & Scaling: Build early operational playbooks, streamline internal communication, and manage critical vendor and institutional partner relationships.
• Special Projects: Take ownership of ambiguous, high-urgency business challenges from inception to handoff.

• Top-Tier Pedigree: 2-5 years of experience at a top management consulting firm (McKinsey, Bain, BCG) or Big 4 strategy practice, ideally paired with high-growth startup experience.
• Commercial & Analytical Rigor: Exceptional problem-solving skills with a proven track record of breaking down complex, unstructured business problems.
• High Velocity & Judgment: Strong bias for action, comfortable moving fast in ambiguous environments with uncompromising discretion.
• Polished Communication: Concise, high-signal written and verbal communication tailored for executive and partner-facing contexts.
