Why This Role Exists

We are hiring an Executive Assistant to provide comprehensive administrative and operational support to our General Counsel/Vice President of Enterprise and Governance. The role requires an elite operational partner to streamline workflows, coordinate critical stakeholder engagements, and protect executive time. This role goes beyond basic scheduling; it is built for an administrative professional who brings structure, predictability, and clarity to a highly dynamic corporate environment.

What You’ll Do

• Manage a complex, shifting calendar and coordinate comprehensive travel arrangements to fully optimize the executive's daily schedule.
• Ensure the executive is thoroughly prepared for all internal and external engagements by assembling meeting materials, presentations, and coordinating preparatory reviews.
• Serve as the primary point of contact and liaison for internal teams and high-profile external stakeholders, managing sensitive correspondence with diplomacy and a clear understanding of the executive's voice.
• Track ongoing priorities, align stakeholders, surface potential roadblocks early, and simplify decision-making processes across the enterprise and governance portfolio.
• Establish repeatable administrative workflows to reduce friction and improve day-to-day operational efficiency across the team.
• Provide hands-on assistance with special projects, research tasks, and corporate organizational initiatives as needed.
• Maintain the highest level of confidentiality and discretion when handling sensitive legal, enterprise, and corporate governance information.

Minimum Qualifications

• Multiple years of experience providing executive-level administrative support in a fast-paced, high-accountability, high growth environment.
• Proven track record of managing complex calendars, travel logistics, and optimizing schedules across competing priorities.
• Strong technical proficiency with G-Suite, Slack, and internal collaboration tools like Notion.
• Demonstrated ability to exercise independent judgment and solve administrative challenges with minimal direction.
• Excellent interpersonal and communication skills to effectively build trust and represent the executive to outside parties.
• Ability to provide flexible support to accommodate fluctuating project timelines, including occasional traveling for in-person support across the USA when required.

Preferred Qualifications

• Prior experience supporting a legal, corporate governance, or government relations executive at a fast paced startup.
• Track record of creating structured organizational tools, databases, or processes to optimize team workflows.
• Experience navigating strict confidentiality constraints or sensitive regulatory environments.

Indicators of Success

In the first six months, a successful Executive Assistant will:

• Deliver a seamless rhythm of calendar and communication management that significantly increases the daily leverage and focus of the General Counsel.
• Build deep trust across internal teams and external partners, acting as an effective, reliable gatekeeper and facilitator for the executive's office.
• Introduce structured administrative workflows that allow the executive office to operate proactively rather than reactively.
• Demonstrate proactive anticipation of executive needs, ensuring all meeting materials and context are delivered accurately and ahead of schedule.
• Navigate fluctuating workloads and shifting meeting constraints with calm, structured execution.
