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)

How We Work

  • On-Site in SoHo NYC 5 days per week

  • No PMs, no EMs—no bureaucracy - We hire product-minded engineers who spot user pain, propose solutions, and ship. Debates happen in PRs, not meetings. You’ll talk directly with founders, designers, and customers—then launch.

  • Ownership over oversight – you pick the tools, set the roadmap, drive release.

  • Tiny, trusted, world-class team – 10 total, 7 engineers, each with 10+ years of experience.

  • Independence with backup – high autonomy, but a room full of experts ready to pair, review, and celebrate wins.

About Us

  • $50M valuation and years of runway – plenty of fuel, no fundraising fire drills.

  • LLM-first from day one – we build with AI at the core, not as a bolt-on.
