About the role

Demo Engineer responsible for end-to-end demo environments, data, scripts, and certification standards to enable consistent, credible demos. Builds demo frameworks, self-service assets, and AI-assisted tooling; collaborates with Product, Product Marketing, and Enterprise Architecture to shape demos and narratives for Zip's pre-sales efforts.

Responsibilities

  • Own demo environment build and operations: Design, build, and maintain the demo environments, data sets, demo pathways, and demo scripts every SEs uses.
  • Build self-service tooling and templates: Turn demo-builds into packages assets that SEs and AEs can pull directly.
  • Shape our demo narratives and storytelling: Develop the talk tracks, narrative arcs, and messaging that turn technical features into a story every SE can tell.
  • Keep demo assets in lockstep with releases: Partner with Product and Product Marketing so new agents, integrations, and vertical use cases ship with a working demo environment and script.
  • Automate scripting and asset generation with AI: Use LLMs and AI coding tools to generate and maintain demo scripts, synthetic data, and environment scaffolding, cutting manual build time on every new demo asset.
  • Automate end-to-end demo workflows with Playwright: Script and maintain Playwright-based flows that walk through full demo scenarios automatically, so environments get validated and refreshed without manual QA.
  • Build with AI-native development tools: Prototype and ship internal tooling using tools like Replit and Lovable, taking new demo assets from idea to working build.
  • Build and maintain agentic loops: Design agent workflows that can prepare, validate, and repair demo environments on their own, catching broken flows before an SE does.

Qualifications

  • 2–5+ years in technical pre-sales, sales engineering, or demo engineering at a high-growth B2B SaaS company.
  • Real hands-on build skills: scripting fluency (Python, JavaScript/TypeScript, or similar), comfort with REST APIs and webhooks, and enough cloud/infrastructure familiarity (AWS, GCP, or Azure) to stand up and operate a demo environment without waiting on engineering.
  • Hands-on experience using AI to automate scripting and asset generation
  • Experience automating end-to-end workflows with Playwright or a comparable browser-automation framework, for demo environment validation, regression testing, or scripted walkthroughs.
  • Direct experience building with AI-native development tools such as Replit, Lovable, or similar. Comfortable going from a blank canvas to a working prototype largely through AI-assisted building.
  • Experience designing and maintaining agentic loops: multi-step AI agent workflows that execute, evaluate, and self-correct.
  • A systems thinker who can tell the difference between fixing the one-off request in front of them and building the thing that prevents the next ten.
  • Strong storytelling instincts: you know the difference between a feature tour and a demo that lands, and you can teach that difference to other people.
  • A strong cross-functional operator: you'll work daily with SE leadership, Product, PMM, and Enterprise Architecture, and you know how to get alignment without a committee.
