Senior / Principal Demo Engineer

As a founding Fin Demo Engineer, you'll own the platform and tooling that powers every Fin demo at Intercom - the environments, seeded data, integrations, reset infrastructure, and reusable building blocks our Solutions Engineers rely on every day. You won't be running demos yourself. You'll be the force multiplier behind the people who do. This role sits at the intersection of Product, GTM, PMM, Enablement and Engineering - with outsized leverage on revenue.

• 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, creating UI and workflows so SEs can spin up, reset, and tailor demo accounts in minutes - not hours.
• Use AI to prepare demos: research prospects, synthesize realistic org structures and conversations, and auto-configure demos for specific verticals and use cases.
• 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.
• Partner with Enablement to 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, through strong collaboration with product teams.
• Codify what works: turn patterns from the field into tools, templates, and playbooks the whole GTM org can use.

• 6+ years building software in a customer-facing technical role - Solutions Engineering, Developer Relations, Founding Engineer, or similar.
• Hands-on AI/LLM product experience: built with LLMs, understand RAG, tool use, agents, and evals, and 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.
• Measurably more productive with Claude Code or equivalent agentic coding tools, with concrete examples of AI doubling 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; an eye for what makes a demo land - the difference between a feature walkthrough and a story that closes deals.

• 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.
