Mid-Level Full Stack Developer – SaaS Product 40 hrs/week

We're a vertical SaaS company building software specifically for pool service operators — CRM, field app, billing, scheduling, chemical tracking, and AI integrations. We have a senior developer leading architecture and the hardest problems. We need a strong mid-level developer to sit alongside him and own a real chunk of the product. This is not a bug-fix role. You'll be building meaningful features — billing flows, third-party integrations, mobile functionality, UI improvements, and more. If you need someone to hold your hand on product decisions, this isn't the right fit. If you can read a feature spec, ask the right questions, and ship clean work, we want to talk. **What you'll be working on** - Billing flows and Stripe/QuickBooks integrations - Checkout and onboarding improvements - Mobile features (React Native field app) - UI/UX refinements across CRM and field app - Service agreements, work order logic, route management - GPS/geofencing and time-tracking features - Data import/export tools **Stack** React, React Native, JavaScript, Node.js, REST APIs, Supabase, GoHighLevel integrations **Requirements** - 3+ years of real product development experience - Strong React and React Native — non-negotiable - You must code with AI tools (Cursor, Copilot, Claude, etc.) — this is not optional. We move fast and expect you to as well. - Has owned features end-to-end inside a live product - Comfortable reading a feature spec and making decisions without constant direction - Communicates clearly in English — you'll work directly with our senior dev daily - Available 30-40 hours/week with set hours between 8 AM–5 PM Mountain Time (UTC-6) - Long-term if it's a fit **To be considered, complete this free task and send it with your proposal:** Write out how you would build this feature: "A button on the customer profile page that opens a pre-filled SMS thread in GoHighLevel for that customer." No code required. Give us the breakdown: what components you'd create, how the logic would work, how you'd connect it to the GoHighLevel API, and which AI tool you'd use to help build it. Should take 20–30 minutes. This is step one — we won't review proposals without it. **Also include:** - A specific example of a time you used AI to build a feature - Your React and React Native experience — be specific - Your timezone and available hours within 8 AM–5 PM MT
