We build trust in AI by making it more accessible, safe, and useful. We build trust with each other by showing up for each other professionally and personally, creating an environment that enables all of us to do our best work. • Trust: • Customer Obsession: We deeply understand our customers’ business goals and relentlessly focus on driving outcomes, not just technical milestones.

Responsibilities
• Sierra’s engineering team has ~40 mostly senior engineers, including Mihai, Belinda, Arya, and Wei. We work in small, autonomous teams oriented around customer problems. In this role, your customer is our Sales Engineering and GTM team—and, through them, every prospect who meets Sierra for the first time. Here are some examples of what you’ll work on: • 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.
