Sierra is a leading platform for customer-facing AI agents, partnering with major brands like The GAP, Rocket Mortgage, SoFi, Sutter Health, and SoftBank to transform customer service and business growth. The company is founded by Bret Taylor (former Salesforce co-CEO, Facebook CTO, Google Maps co-creator) and Clay Bavor (former Google Labs leader, AR/VR pioneer).
The Tech, Media & Telecom team builds AI agents for high-impact moments—service disruptions, product launches, major events—handling millions of customer interactions. The team focuses on three verticals: Telecommunications (personalizing subscriber experiences, optimizing plans, building loyalty), Media (turning subscriptions into ongoing personalized relationships), and Technology (delivering white-glove support at scale).
In this role, you will design and deliver production-grade AI agents that are mission-critical and drive revenue. You'll own the complete Agent Development Life Cycle (ADLC) from pilot through deployment and continuous iteration, building, tuning, and evolving agents in production environments. You'll partner directly with enterprise leaders and cutting-edge startups to understand business challenges and build transformative solutions. Your work will guide the evolution of Sierra's core platform as you surface unmet needs, prototype new tools, and collaborate with research, product, and platform teams.
Recent project examples include: agents that pursue goals over weeks/months with intelligent outreach timing and channel selection; personalization systems using Sierra's Context Engine to combine customer data and behavior for autonomous improvement; conversational discovery agents reasoning across content catalogs; troubleshooting agents integrated with telecom and device systems; and voice experiences with tailored personas.
