We need someone who is an expert in Flutter, Firebase, Stripe, to create a Progressive Wed App from an app that has been approved for Android but not yet approved for IOS. The app has already been built, we need an expert to now create a web app version, add the link to the website, handle the Stripe integration for a subscription model. Once this is complete there is a chance to remain on the team to update the app as needed and handle updates. As the app was built in Flutter this should nto take long at all to convert to a web app.

The Role In One Line You are the solo product designer who will bridge the gap between creative vision and shipping real code. You will design, build, and implement highly polished consumer-facing mobile experiences that connect our app directly to the Simply Bread brand. We need a "team of one" who takes our B2C app from generic screens to a beautiful, intuitive marketplace that bakers and buyers love. Who You Are You are a relentlessly curious designer who hates waiting on engineers to push updates. You have a deep understanding of B2C and marketplace products, knowing how to weave brand identity into every button, flow, and typography choice. You thrive as an individual contributor in a fast-paced startup trench, operating with minimal direction to solve complex user problems. You do not need to be spoon-fed ideas; you bring strong independent judgment and full-stack capabilities to the table. You value execution speed, using AI tools to iterate fast before locking in pixel-perfect layouts. Most importantly, you care obsessively about the total user experience, from the first onboarding click to the final checkout. What You’ll Actually Do - Architect and implement a beautiful, highly functional B2C mobile experience. You will push updates directly into the product, elevating our app from generic SaaS layouts to a cohesive, brand-aware consumer story. - Execute fast design iterations and ship improvements quickly. You win daily by using AI workflows (like v0 and Lovable) to speed up discovery, finalizing pixel-perfect screens in Figma, and pushing UI updates without bottlenecking the engineering team. - Optimize our design-to-development pipeline. You will build comprehensive, modern design systems that enforce visual consistency, typography standards, and flawless onboarding flows across the entire platform. - Take 100% ownership of the app's UX as a solo designer. You will operate with high autonomy, bringing independent ideas to the founders and engineering team without needing detailed direction or hand-holding. - Solve complex marketplace puzzles with rapid turnarounds. You will redesign and ship critical user flows—like multi-variable checkout and local delivery routing—within a week-scale timeframe. What We're Looking For - 3+ years of UX/UI design experience building consumer (B2C) or marketplace apps, specifically operating as a solo designer or "team of one." - Mastery of Figma and AI-assisted design workflows (v0, Lovable), plus the technical capability to implement designs and push UI updates directly. - A non-negotiable obsession with brand identity, typography, readability, and complete user flows—you do not just make screens; you build cohesive product stories. - Startup Mindset: You move fast, thrive on limited inputs, and favor independent execution in the trenches over perfectionism and constant direction. - Familiarity with user behavior analytics (like Hotjar) to make data-driven decisions. Bonus Points: - Direct experience with marketplace, creator, or commerce-focused lifestyle apps. Why Simply Bread We make a smart bread oven and the ecosystem around it: a marketplace app, POS, pickup lockers, and the hardware that lets bakers go from hobbyist to business. We're growing across the US, Canada, Australia, and Europe!
