Executive Assistant, Product & Agent Development

About us At Sierra, we’re building a platform to enable every company in the world to build better, more human customer experiences with AI. We partner with industry leaders such as SoftBank, Uber, Rivian, CLEAR, and Sutter Health. 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 Family. 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: Serve as a trusted partner to Sierra’s Head of Product & Agent Development, supporting a rapidly growing product, engineering, and design organization. Proactively manage the leader’s complex calendar, meetings, and travel, coordinating with direct reports, the broader leadership team, and external stakeholders. Coordinate domestic and international travel across EMEA and APAC time zones, with careful attention to itineraries, agendas, logistics, and preparation. Anticipate needs, surface potential conflicts, and independently resolve issues when priorities change or timely guidance is unavailable. Prepare the leader for meetings with relevant briefing materials, organizational context, and clearly defined priorities.
