Ship features end-to-end across the SEOTop Secret stack — marketing site, client portal, Stripe billing, Supabase data model, cron automations, and LLM-powered workflows.
Mission
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.
What you'll own
Marketing site (seotopsecret.com) and client portal (clients.seotopsecret.com) — architecture, releases, CWV, bundle budgets
Stripe layer — subscriptions, webhooks (signed + idempotent), plan changes, proration, failed payments
Scheduled automations — Vercel cron + LLM API jobs powering monthly reports, briefs, and publishing flows
Component system, design tokens, dark mode, and i18n (EN + es-MX + en-AU with hreflang trio)
Observability — error tracking, deploy monitoring, uptime, incident response
What you need
~5+ years shipping production Type Script full-stack — React, Node, and a Postgres-backed product

~ Deep Next.js App Router: RSC vs client components, Server Actions, Route Handlers, caching, middleware

~ Supabase or equivalent BaaS — writing RLS policies, migrations, triggers, and auth flows without footguns

~ Stripe subscriptions in production — webhooks,



plan changes, proration, dunning — you've debugged a real billing incident

~ LLM API integrations in production — you've shipped a feature that calls an LLM and handled tokens, cost, latency, and error modes

~ Tailwind + Framer Motion + a real eye for polish — the product is the marketing; the UI has to feel like it

~ Bonus: technical SEO fundamentals (hreflang, canonical, sitemap, schema) — the product IS an SEO tool, so you'll build what you'd use

What we offer
Remote-first, async-first — pick your timezone within ±3h of CET, CDMX, or AEST
Founder as manager — zero middle layers, direct stake in what ships

Real P&L; visibility: pricing, margins, MRR, churn — you see the same dashboard we do

Competitive salary + meaningful equity — calibrated to your market

In the doc, include

~1 A production feature you shipped end-to-end — link to the live surface (or a demo) and a one-paragraph on what you built and why
~2 A migration, schema, or RLS policy you wrote — paste the SQL, redact anything sensitive, explain the tradeoff in two lines

~3 A 30-second take on the last time you picked a simpler architecture over a more impressive one
