Full-Stack Backend Developer — Hosting, Tracking & Payments

Fully remote · Start hourly → convert to full-time

About us

We build and scale health & wellness digital subscription / web products (info products, assessments, companion-style apps). Product + growth move fast: a lot of early surfaces are vibe-coded, then need to become real production systems next to media buying and analytics.

About the role

Backend-leaning full-stack engineer who can take vibe-coded funnels and products (e.g. Base44-style builds, GitHub exports, AI-generated apps) off the sandbox and onto self-hosted infrastructure — then wire pixels, GTM, GA4, Amplitude, and payment APIs so ads and subscriptions actually track and charge correctly.

You do not need quiz-funnel DNA. That’s a plus, not a requirement. You do need to read PSP/docs carefully and ship reliably.

What you’ll do

• Export / migrate vibe-coded projects (GitHub / similar) into clean repos and self-hosted environments
• Own hosting, deploys, env/secrets, basic ops for funnel + product surfaces
• Connect Meta / Google (and related) pixels; implement GTM + GA4 events correctly (purchase, subscribe, trial, etc.)
• Instrument Amplitude (or equivalent product analytics) so growth can see funnels end-to-end
• Integrate payment APIs — Stripe, Adyen, NMI (and similar) — checkout, webhooks, subscription status, refunds as needed
• Work with PMM / UA / product on event naming, debug broken tracking, harden what “vibe code” left fragile

Must-have

• Strong backend + enough front-end to ship funnel/product pages and tracking scripts
• Real experience putting apps on self-hosted / VPS / container infra (not only managed toy deploys)
• Hands-on GTM + GA4 (and pixel) event wiring you can walk through
• Amplitude (or very similar product analytics) in production
• At least one of Stripe / Adyen / NMI (others welcome) — comfortable reading API docs + webhooks
• English enough to read technical docs and async with the team

Nice-to-have

• Quiz / long-form web funnel or subscription paywall products
• PSP aggregators (Solidgate, Apigate, etc.)
• CAPI / server-side events; Meta signal quality hygiene
• Node / Python / PHP / Next — whatever ships; stack is secondary to shipping production

Not a fit

• Pure front-end / design-only
• Never owned hosting or production deploys
• “I’ll learn payments later” with no API/webhook history
• Looking only for a slow enterprise FT ramp with no hourly start

How we hire

This is a full-time seat, but we start immediately on hourly until we’ve shipped enough together to convert to FT.

How to apply

In your application (or first message), list exactly what you can already do from what we need — short yes/no or 1-line proof for each:

1. Take a vibe-coded / AI-built app (GitHub export / Base44-style) and move it to self-hosted infra
2. Own hosting / deploys / env / secrets for a live web product
3. Wire Meta/Google pixels
4. Implement correct events in GTM + GA4 (purchase / subscribe / trial / etc.)
5. Set up or run Amplitude (or equivalent) on a product funnel
6. Integrate payments via API docs — which of Stripe / Adyen / NMI (or similar) you’ve done, including webhooks / subscriptions if any
7. Hourly availability to start now + when you could go full-time

Optional plus: quiz / long web-funnel or subscription paywall experience (not required).
