Executive Assistant

About the Company

Pilots don't train with real passengers. Actors don't rehearse with real audiences. Yet, the most consequential decisions in society are often pushed straight to production.

Simile is changing that. We have built the first AI simulation of society, populated by generative agents based on real humans. Our research pioneered the field of AI-based simulation, proving it is possible to model human behavior with high accuracy. Today, we are developing a Foundation Model to predict human behavior in any situation, at any scale.

We have raised $300M in total funding, with a $2B post-money valuation in our latest round. Our investors include Greenoaks, Index Ventures, Hanabi, A*, Bain Capital Ventures, Factory, CVS Health Ventures, and Definition.

About the Role

Simile's go-to-market engine is scaling fast. Our COO and GTM leaders spend their weeks with Fortune 100 executives, in customer meetings and on the road, while also building the teams, systems, and operating rhythm behind a 5x revenue trajectory. As Senior Executive Assistant to the COO & GTM Leadership, you'll make sure their time goes to what matters most.

This is not a calendar-only role. You'll be a trusted strategic partner to the COO and the leaders across sales, marketing, and customer success. You'll anticipate what's coming, juggle competing priorities across several executives, and keep a fast-moving, customer-facing organization running smoothly. You'll have real ownership over how the GTM leadership team operates as we scale.

In this role, you will:

• Executive Partnership: Act as the primary partner to the COO. Manage their calendar, inbox, and priorities, and communicate on their behalf with customers, partners, investors, and candidates with discretion and professionalism.

• Customer-Facing Coordination: Coordinate executive customer meetings, onsites, and business reviews with Fortune 100 accounts. Make sure every interaction is well-prepared and reflects the quality bar of the company.

• Operating Cadence: Support the GTM leadership operating rhythm, including staff meetings, pipeline and forecast reviews, and planning cycles. Own agendas, pre-reads, notes, and follow-through on action items.

• Travel & Logistics: Plan and manage complex domestic and international travel for multiple executives, including multi-city customer trips, conferences, and last-minute changes.

• Events & Offsites: Plan GTM offsites, sales kickoffs, executive customer dinners, and industry events from concept through execution.

• Cross-Functional Partnership: Work with the CEO's office, Chief of Staff, revenue operations, marketing, and other EAs to align schedules, priorities, and shared company initiatives.

• Process & Scale: Build the systems, templates, and workflows that let the office of the COO scale as the GTM team grows. Take on special projects.

• Multi-Executive Support: A proven track record of supporting several senior leaders at once, with the judgment to balance competing priorities without dropping anything.

• Discretion & Judgment: Experience handling confidential information, and the judgment to know when to act, when to elevate, and when to say no on an executive's behalf.

• Customer-Facing Polish: You represent your executives well with enterprise customers, partners, and investors, in writing and in person.

• Exceptional Organization: Excellent time management with superb attention to detail. Nothing falls through the cracks.
