Staff Front-End Engineer

Henry.ai looking for a product-obsessed front-end engineer with impeccable design taste—someone who can take a fuzzy 0→1 idea, sketch the experience, and ship a UI that customers rave about. Our users leave 2am voicemails to praise us about new features (yes this really happens)—we’re here for that level of impact.

At Henry, shipping is full-stack 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, this is your ticket.

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)
