Staff Fullstack/FrontEnd Engineer Henry.ai looking for a Fullstack/FrontEnd Engineer who is product-obsessed with impeccable design taste and front-end depth—someone who can take a fuzzy 0→1 idea, sketch the experience, and ship a UI that customers rave about.

At Henry, shipping is fullstack ownership—work with designers, launch fast, and gather user feedback minutes after release. If you dream in components, argue passionately about react architecture, and want to build alongside a team of elite engineers growing at hockey-stick speed, we would love to meet you.

What You’ll Do

• Own the Experience End-to-End – brainstorm with founders and users, prototype with our design team, implement in TypeScript/React/Tailwind, and push to prod the same week.
• Architect for Scale & Delight – design front-end systems that are fast, accessible, and resilient, while sweating the details of motion, typography, and responsiveness.
• Shape a 0→1 LLM-Native Product – craft UIs that harness cutting-edge AI features, turning raw model output into magical workflows for brokers.
• Measure, Learn, Iterate – instrument everything, study real usage, and refine until every click feels obvious and every animation feels inevitable.
• Raise the Bar – mentor teammates, codify design patterns, and champion a culture where code reviews double as design critiques.

Must Haves

• 8+ years shipping production front-end for customer-facing products (React/Preact or similar).
• Fluency in TypeScript, modern build tooling, and component-driven architecture.
• A portfolio that proves exceptional visual and interaction design judgment.
• Bias for action & radical ownership—you unblock yourself and others.
• Comfort working five days a week in our NYC office; we believe the best ideas happen face-to-face.

Nice-to-Haves

• Prior 0→1 startup experience—wearing many hats and thriving amid ambiguity.
• LLM or AI-driven UI experience (prompt design, streaming updates, real-time collaboration).
• Deep knowledge of performance, accessibility, and animation best practices.
• Object oriented BE experience (preferably in Golang)
