Founding Engineer (Full-Stack)

**About WashBoard** WashBoard is a two\-sided marketplace for commercial bus and coach fleet washing — an industry that runs almost entirely on phone calls today, with essentially zero software. The MVP is largely built, early demos with both fleets and wash providers have landed exceptionally well, and we launch into revenue this year. We're hiring a founding engineer to own the entire platform and build it into the operating system for this market. Being upfront from line one: this starts at 25–50% of your time and converts to full\-time as revenue scales. Comp is equity\-weighted — 3–8% ownership — plus cash. Details below. **Why this is real** Most early marketplaces die trying to solve distribution. Ours is solved. My co\-founder Jack has spent two decades in this industry; his previous company built the leading machine for washing buses, he has 1,500\+ customers from that business, and he personally knows most of the operators and providers in the market. When we demo, people take the call because they know him. I run product. You would own everything technical. **What exists today** A production\-grade MVP, TypeScript end\-to\-end: * React web app (Vite, TanStack Query, Tailwind \+ shadcn) — mobile\-first, built for drivers using it from a coach cab * Node/Express API with an OpenAPI contract and generated typed clients * Prisma \+ PostgreSQL; session auth; a booking state machine with full audit history; SERIALIZABLE booking holds to prevent double\-booking * Map\-driven search and discovery with route\-aware detour\-time logic (Leaflet \+ OSRM), two\-sided operations for fleets and providers, cross\-border USD/CAD pricing **What you'll build** Near\-term, everything between here and revenue: launch hardening, marketplace payments (Stripe Connect — payouts, refunds, disputes, KYC), security hardening, performance, and provider onboarding tooling. The bigger arc is why this role is interesting. We're going to move the industry's workflows, which currently happen via phone calls, into an AI\-led operations layer: intelligent scheduling, pricing intelligence, voice agent automation for the phone\-first side of the market, and much more. You'd architect that from the ground floor. First 90 days: take the MVP through private launch — payments live, security hardened, the first paying fleets and providers transacting, and instrumentation in place to see what's working. The platform will launch publicly within 120–180 days. **Who you are** * You've shipped web or mobile products to at least low\-thousands of real users — and you can send links/portfolio * You've been the sole or lead engineer on something that mattered: production quality, testing, security, and uptime were on you * You use AI heavily in your workflow (Claude Code, Cursor, or similar) and ship at a pace that surprises people — with the judgment to verify what you ship * Payments or marketplace experience is a plus (Stripe Connect especially) * You want ownership and
