We are AI Native We are building an AI native company where AI is an integral part of how we build and operate. AI tool usage during interviews varies by role. You may be asked to demonstrate proficiency with AI tools, discuss how you leverage AI, or complete interview exercises without AI assistance. Your Recruiter will provide clear guidance as you move through the interview process. Undisclosed use of AI not previously discussed with or approved by your Recruiter may impact your candidacy. About The Team The AI Lab is a small, founder-led team operating like a zero-to-one startup inside Ironwood Digital , building the company’s next chapter. Our mission is to transform Ironwood Digital from the app you open to find your family into an intelligent operating system families rely on daily. We design and build an AI-powered layer on top of our family graph, leveraging our core location technologies and global 100 million-user base to proactively surface what matters across location, schedules, and everyday life. About the Job 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. For candidates based in the US, the salary range for this position is $190,000 to $280,000 USD. For candidates based out of Canada, the salary range for this position is $220,000 to $260,000 CAD. Note: Please be aware that the job title for positions in Canada will be "Developer" in lieu of "Engineer." We take into consideration an individual's background and experience in determining final salary - therefore, base pay offered may vary considerably depending on geographic location, job-related knowledge, skills, and experience. The compensation package includes a wide range of medical, dental, vision, financial, and other benefits, as well as equity. 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 If there's one trait we need above all others, it's self-starter energy. As we've gotten bigger, we've been more open to roles with cle
