Principal Demo Engineer

Job Title: Principal Demo Engineer

We are looking for a Principal Demo Engineer to join our team at Fin. As a Principal Demo Engineer, you will own the platform and tooling that powers every Fin demo at Intercom. You will be responsible for building first-class demo features into Fin itself, creating UI and workflows so Solutions Engineers can spin up, reset, and tailor demo accounts in minutes.

Key Responsibilities:

• 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.
• 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.
• 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.
• Let SEs move faster. Build templates, libraries, and scripting hooks so SEs can compose complex demo scenarios with guardrails - not raw access to production.
• 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.
• Partner with Enablement. Design hands-on training, demo libraries, and certification paths that ramp SEs and AEs faster than anywhere else in the industry.
• Stay one step ahead of the product roadmap. When a new Fin capability ships, the demo for it should already exist. This happens with strong collaboration with our product teams directly.
• Codify what works. Turn patterns from the field into tools, templates, and playbooks the whole GTM org can use.

Requirements:

• 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-haves:

• 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, including synthetic or anonymised data.
• Prior work that bridged engineering and revenue - lighthouse deals, founding-engineer scope, or solutions engineering platforms.

Benefits:

• Competitive salary and meaningful equity.
• Comprehensive medical, dental, and vision coverage.
• Regular compensation reviews - great work is rewarded!
• Flexible paid time off policy.
• Paid Parental Leave Program.
• 401k plan & match.
• In-office bicycle storage.
• Fun events for Intercomrades, friends, and family!
