ABOUT US At Sierra, we’re creating a platform to help businesses build better, more human customer experiences with AI. We are primarily an in-person company based in San Francisco, with growing offices in Atlanta, New York, London, Paris, Madrid, Munich, Singapore, Tokyo, and Sydney. 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 https://www.linkedin.com/in/brettaylor/ and Clay Bavor https://www.linkedin.com/in/claybavor/. 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 - Transcription: How do we enable accurate speech-to-text and automatic speech recognition across 100s of languages? What infrastructure do we need to do this at low latency? - Synthesis: How do we generate speech that is precise and matches each customer’s desired brand and style? - Runtime: How do we adapt our agentic loop to accept real-time streams of audio, instead of just text? How do we ensure we handle interruptions, disconnects, and transfers reliably? - Scaling: Build the infrastructure to enable Sierra to handle millions of calls a day. - Telephony: Build real-time integrations to telephony systems and call centers to enable Sierra to pick up the phone, and make outbound phone calls, reliably. WHAT YOU'LL BRING - A passion for being on the frontier of AI products. -
