Principal Demo Engineer

Intercom Intercom · Enterprise · EMEA · Customer Success & Solutions

The Principal Demo Engineer will own and build the platform and tooling for Intercom's AI Customer Agent, Fin. This includes managing demo environments, seeded data, integrations, and reusable components to enable Solutions Engineers. The role also involves embedding with product teams to support new releases, create training materials, and collaborate across Product, GTM, Enablement, and Engineering to ensure effective product demonstrations.

What you'd actually do

  1. Own the Fin demo platform end-to-end. Multi-tenant mock workspaces, seeded data, configuration, reset infrastructure, and guardrails that make demos reliable, fast, and safe.
  2. Build first-class demo features into Fin itself. Create UI and workflows so SEs can spin up, reset, and tailor demo accounts in minutes - not hours.
  3. Use AI to prepare demos. Use Fin itself (and other models) to research prospects, synthesize realistic org structures and conversations, and auto-configure demos for specific verticals and use cases.
  4. Let SEs move faster. Build templates, libraries, and scripting hooks so SEs can compose complex demo scenarios with guardrails - not raw access to production.
  5. Show Fin across every surface it touches. Web Messenger, mobile SDKs, voice, email, Slack, API-driven workflows. The demo should match how customers will actually deploy.

Skills

Required

  • 6+ years building software in a customer-facing technical role - Solutions Engineering, Developer Relations, Founding Engineer, or similar.
  • Hands-on AI/LLM product experience. You've built with LLMs, you understand RAG, tool use, agents, and evals, and you know the practical limits of current models.
  • Strong full-stack chops: TypeScript on the front end plus one strong backend language (Ruby, Go, or Python), and comfort working across web and mobile (iOS/Android or React Native).
  • Deep familiarity with SDKs, wrappers, and developer-facing APIs - you've both built them and integrated against them. RESTful APIs and SaaS integrations are second nature.
  • You've made yourself measurably more productive with Claude Code or equivalent agentic coding tools. You can show concrete examples of where AI doubled your output - and you'll teach the rest of the SE org to do the same.
  • Design sensibility. You care how the demo looks, not just what it does. You know that a demo that works but looks amateurish loses deals.
  • An eye for what makes a demo land - the difference between a feature walkthrough and a story that closes deals.

Nice to have

  • Background in customer support, contact center, or CX tooling.
  • Experience building internal platforms or developer tooling at scale.
  • Experience designing or maintaining multi-tenant demo or sandbox environments, includ
