Ship features end-to-end across the SEOTopSecret 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 TypeScript 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
