Responsibilities
Own Sierra’s demo platform: Design and build the systems that power our demo environments— multi-tenant “mock orgs,” seeded data, configuration, and guardrails that make demos reliable, fast, and safe
Build first-class demo features into Agent Studio and the core product: Create UI and workflows so SEs can spin up, reset, and manage tailored demo accounts in minutes—not hours—without calling an engineer
Use AI to personalize and prepare demos: Leverage Sierra’s own agent stack (and other models) to research prospects, synthesize realistic org structures, conversations, and data, and auto-configure agents and flows for specific industries and use cases
Expose “under the hood” views for SEs and prospects: Add thoughtful panels, timelines, and visualizations that make it easy to show how Sierra thinks, decides, and integrates—without overwhelming the UI or leaking sensitive details
Build internal tools that let SEs move like engineers: Create templates, libraries, and scripting hooks that let SEs compose complex demo scenarios and edge cases with guardrails instead of raw access to production systems
Instrument and iterate: Track how demo flows perform (time to “aha”, win rates by template, setup time per SE), and use that data to drive your roadmap alongside Sales Engineering, Product, and Agent Studio
Ship real production code: Everything you build should be robust enough to live in the main product—tested, observable, and maintainable, not a separate demo toy that rots over time
