Senior Full-Stack Engineer

Mission Own the SEOTopSecret product end-to-end — the marketing site, the client portal, the billing layer, the data model, and the automations that turn research into published content. You’ll own the architecture, the releases, and the technical calls on the stack that ships every client deliverable. Why this role exists Our founder has 25+ years in SEO but doesn’t write code. The stack — Next.js 16 (App Router), Supabase (Postgres + Auth + Storage + RLS), Stripe subscriptions, Vercel cron, and LLM API integrations — ships every client deliverable. We need one senior full-stack engineer who can own it end-to-end instead of coordinating a vendor team.
