Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Founding Design Engineer - **Company:** PROBOOK LLC - **Location:** Manhattan, KS, United States - **Experience:** Experienced - **Contract:** Permanent contract - **Skills:** Artificial Intelligence, Cursor, Design of User Interfaces, Web Platforms, Rollup, Claude Code, Production Code, Front End Software Development - **Published:** November 10, 2026 - **Apply:** https://www.juju.com/job/28_25197_0db31575bd7635818111c68c54fab1ae ## About the Role * 4-6 years of product design experience; the ideal trajectory is two serious stints (2+ years each), ideally at startups * has built bug-free frontend in production, doesn't need another engineer to make this happen * B2B SaaS background: you understand that enterprise and ops-focused product design is fundamentally different from consumer, and you've lived that difference * Strong portfolio of shipped work, * A track record of shipping frontend code independently - not just handing off specs, but owning changes through to production * Fluency with AI-assisted development tools (Claude Code, Cursor, or similar) is non-negotiable - we'll ask specifically about this * Can take a product problem, spin up multiple end-to-end flows using AI tooling, and pressure-test tradeoffs quickly and independently Product Sense & Execution * Exceptional design taste and detail orientation - you notice typographic inconsistencies and can't let them go * Communicate with clarity and precision - you can articulate the why of a design decision, not just show it * Strong enough product instincts to prioritize correctly without constant guidance; you work on the most important flows, not the most interesting ones * Proven ability to absorb context fast and be dangerous with incomplete information * High-velocity iteration mindset - scrappy and hungry, not perfectionist Mindset ## Description * Own the quality of Probook's UI/UX across our chrome extension, mobile product, and web platform end-to-end * Translate customer pain points from real conversations with real operators into product and UX improvements that ship * Obsessively explore the problem space and iterate before coming up with a solution. You know that the best product decisions come from a deep understanding of how operators work, not from settling on the first viable answer. * Independently ship front-end changes: you'll be making actual production code changes, not handing off to engineers and walking away * Move fast and sweat the details - you're able to match the team's velocity and turn things around in hours, not days/weeks without compromising on quality Product Partnership * Work directly with engineers from spec to ship, closing the gap between what gets built and what should be built * Be a daily thought partner to the founders on product direction, with a real seat at the table on decisions that matter * Work directly with customers in the field to understand workflows and pain points. You can and should expect to be on calls with customers regularly to hear directly from them * Identify UX problems before customers surface them; anticipate common tradeoffs and design around them, * Roll-up-your-sleeves mentality; you're the first designer, which means you define everything from scratch * Intrinsically motivated to get better at your craft: this shows up in how you spend your time outside of work * Comfortable being embedded with the C-suite daily and operating in a high-trust, high-accountability environment * In-office, 5 days a week in Manhattan: this role will need to absorb the collective product thinking of the company more than anyone else on the team, * The Tailwinds: $700B industry with clear tailwinds: AI adoption, labor shortages, and generational transitions creating demand for operational modernization. We are defining the category, not fighting for share. * The Traction: $XXM ARR in 18 months. Cash-flow positive. Product-market fit proven; now we're scaling. * The Team: >30 people, our founding team comes from the space and has spent thousands of days onsite with our customers. We live the space. We're also becoming one of the most talent-dense start-ups in NYC (MIT, Harvard, UPenn M&T, Waterloo, Citadel, Palantir, ICPC world finalists, IMO Gold Medalists).
