The posting, in Sierra's own words
archived Oct 26, 2026About us
Sierra is the leading platform for customer-facing AI agents, working with many of the world's biggest brands — including The GAP, Rocket Mortgage, SoFi, Sutter Health, and SoftBank — to transform how they serve customers and grow their businesses. We are primarily an in-person company based in San Francisco, with growing offices across North America, Europe, and Asia. We are guided by a set of values that are at the core of our actions and define our culture: Trust, Customer Obsession, Craftsmanship, Intensity, and a commitment to balancing Family along the way. These values are the foundation of our work, and we are committed to upholding them in everything we do. Our co-founders are Bret Taylor and Clay Bavor . Bret currently serves as Board Chair of OpenAI. Previously, he was co-CEO of Salesforce (which had acquired the company he founded, Quip) and CTO of Facebook. Bret was also one of Google's earliest product managers and co-creator of Google Maps. Before founding Sierra, Clay spent 18 years at Google, where he most recently led Google Labs. Earlier, he started and led Google’s AR/VR effort, Project Starline, and Google Lens. Before that, Clay led the product and design teams for Google Workspace.
What You'll Do:
As an Executive Assistant supporting the leadership function at Sierra, you will provide a wide range of strategic and administrative support to our General Counsel and our Partnerships leaders. Proactively manage several leaders' calendar, travel, and meetings. Collaborate with leaders and team members to ensure meetings are effective by sending preparation materials, following up on action items, and serving as a knowledgeable resource on relevant topics or organizational matters. Draft team and external correspondence on behalf of the leader. Liaise with internal staff and external stakeholders, building and maintaining strong relationships on behalf of the leader. Maintain a high level of confidentiality and discretion with all materials and information. Plan and execute internal events (in-person and virtual), including team offsites, trainings, and team travel. Book travel and hotel accommodations, negotiating contracts as needed. Establish new—and improve existing—administrative systems and processes as part of Sierra’s founding admin team.
