Staff AI Builder (AI Native Mobile Engineer), Family AI Lab

About the role

The role is hard to title because the lines between engineering, design, and product blur fast when you are building the way we are building. The closest description is design-oriented builder. You have a strong aesthetic sense and real opinions about how a product should feel. You can take a loose idea and make it tangible before anyone has finished writing the spec. You understand the value of a polished user experience in the context of agentic software and how to deliver one. You work directly with design, product, and the founder. You are part of the creative process, not downstream of it.

What You’ll Do

• Take rough ideas (sketches, voice memos, half-finished docs) and turn them into something real and clickable, fast. The first version is usually the same day.
• Build prototypes for the surfaces that make the product tangible: the map, widgets, Live Activities, voice, in-app moments where information surfaces automatically. Some will ship. Most will get thrown away. Both outcomes are useful.
• Make tasteful UI calls without waiting for design to spec every pixel. Design refines. You get it 80% there.
• Sit in the room when product direction gets debated. Push back when something doesn't feel right. We need engineers who are part of the conversation, not waiting for the output.
• Use AI tooling aggressively. Orchestrate agents to generate code, write tests, and review your work. The whole point of this team is that a small group with the right tools outperforms a much larger one.
• Ship to test groups, watch how people actually use what you built, iterate. The feedback loop is short and you are inside it.

What We’re Looking For

• Self-starter energy. As we've gotten bigger, we've been more open to roles with clearly defined schedules and processes. That doesn't work in a startup. We need people on founder hours, not office hours — with a huge desire to win.
• You'll be a cofounder of this initiative. You operate without a spec. You'd rather have a conversation, a sketch, and 24 hours than a 30-page PRD and a week.
• You ship every day (or close to it). Not "make progress." Ship. Even rough. Even ugly. Momentum matters more than polish at this stage.
• You're comfortable showing it before it's ready and letting it get torn apart in service of getting to the right thing.
• You push for more. You won't wait to be told what to do. You demand excellence of yourself and the people around you.
• You hold strong opinions and change them when the evidence moves. You push back. You concede fast when wrong.
• You're a customer of what we build. Try it if you haven't.

Deep experience

• Building consumer mobile or web products that real people use.
• Experience in the zero-to-one stage.
• Taste. You can articulate why one design works and another doesn't. You have references. You notice details other people miss.
• Ability to move from a blank screen to a working prototype without anyone holding your hand. Specs make you slower, not faster.
• Deep in at least one of React, Swift, or Kotlin — and comfortable shipping in another.
• Hands-on with AI tools like Claude Code, Cursor, or equivalent.
• Experience with agentic workflows, prompt engineering, context window management, MCP / function calling.
• Map-based or location-driven product work. Understanding of design problems unique to spatial UI.
