About The Position

This 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. The work is not "here is a Figma, build it." The work is "here is a rough idea, what does the first working version look like by the end of day, and what do we learn when we put it in front of someone."

You thrive without traditional specs and get real energy out of shipping something new every day. Energy and momentum matter as much as skill.

Requirements

• Self-starter energy.
• Operate without a spec. Prefer a conversation, a sketch, and 24 hours than a 30-page PRD and a week.
• Ship every day (or close to it). Momentum matters more than polish at this stage. Comfortable showing it before it's ready and letting it get torn apart in service of getting to the right thing.
• Push for more. Won't wait to be told what to do. Demand excellence of yourself and the people around you.
• Hold strong opinions and change them when the evidence moves. Push back. Concede fast when wrong.
• Be a customer of what we build.
• Deep experience building consumer mobile or web products that real people use. Know what good feels like on a phone, and know how it fails.
• Zero-to-one stage experience and the desire to do it again.
• Taste. Can articulate why one design works and another doesn't. Have references. Notice details other people miss.
• Can 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. Don't treat the platform as someone else's problem.
• AI-native in your daily workflow. Hands-on with Claude Code, Cursor, or equivalent. Deep experience with agentic workflows, prompt engineering, context window management, MCP / function calling.

Nice To Haves

• Map-based or location-driven product work. Understand the design problems unique to spatial UI.

Responsibilities

• 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.

Benefits

• Competitive pay and benefits.
• Medical, dental, vision, life and disability insurance plans (100% paid for US employees). We offer supplemental plans for medical and dental for Canadian employees.
• 401(k) plan with company matching program in the US and RRSP with DPSP plan for Canadian employees.
• Employee Assistance Program (EAP) for mental wellness.
• Flexible PTO and 12 company wide days off throughout the year.
• Learning & Development programs.
• Equipment, tools, and reimbursement support for a productive remote environment.
• Free Life360 Platinum Membership for your preferred circle.
