Senior Full-Stack Developer (Supabase, PostgreSQL, Next.js) for Multi-Tenant SaaS, Canada

LiteMile Technologies Inc. (Vancouver, BC) builds simple software for Canadian final-mile delivery contractors and DSPs. Our first product, LiteMile Invoicing, is live. We are now building LiteMile Ops, a scheduling and dispatch platform for delivery companies and their drivers. A complete working prototype already defines every screen, workflow and business rule, with a written walkthrough and automated checks. We need one experienced full-stack developer to build the production version on Supabase and Next.js. What You'll Build - A multi-tenant SaaS where each company sees only its own data, enforced with PostgreSQL row-level security - Office roles and permissions, plus a mobile web app for drivers with sign-in by text message code - Scheduling and dispatch with rule checks, CSV/Excel import, and text message and email notifications - Secure storage for driver documents, English and French, with all customer data hosted in Canada - Hosting, environments, CI/CD, backups and monitoring, set up and owned by you Must Have - 5+ years building production web apps, including at least one multi-tenant SaaS with paying customers - Strong PostgreSQL, including row-level security. Supabase experience is a strong plus - Next.js / React with TypeScript, and Node.js - Experience setting up hosting, deployments and backups yourself (there is no separate DevOps person) - Phone or SMS one-time code login (for example Twilio or Supabase phone auth) - Solid security habits - Based in Canada, able to work as an independent contractor, and willing to sign an NDA and IP assignment Nice to Have - Logistics, delivery, dispatch or workforce scheduling software - Twilio, Stripe or Cloudflare - English/French apps, automated testing (Playwright), speaking French How We Work - Hourly, ideally 25 to 35 hours a week, first release in 3 to 6 months, with ongoing work after launch - We start with a small paid test task - Milestones with an hour estimate for each, a short demo every week, GitHub with pull requests - The prototype and full specification are shared after an NDA To Apply Please start your proposal with the word "Dispatch" and include: 1. Two or three production apps you built, your role in each, and whether they have paying users 2. In a few sentences: how you would make sure one company can never see another company's data in Supabase or PostgreSQL 3. Your availability (hours per week) and earliest start date 4.
