Senior Full-Stack Engineer (MVP) — DTC eCommerce M&A Brokerage + Valuation Platform
 

Scope: Build a production-ready MVP for a brokerage marketplace focused exclusively on DTC eCommerce brands. The platform must (1) onboard sellers via a clean valuation wizard, (2) create gated listings, (3) let vetted buyers browse, filter, inquire, and (4) support payments/fees, KYC, notifications, and basic analytics.

Goal: Ship an MVP we can use to close the first 100 paid customers (listings) and generate serious buyer inquiries.
 

Tech We Expect You To Use

• Frontend / Hosting: Next.js (App Router, TypeScript) on Vercel
• DB/Auth/Storage/Realtime: Supabase (Postgres + RLS, Auth, Storage, Realtime)
  • Realtime via Supabase Realtime or Ably (justify tradeoffs)
• Payments: Stripe (prefer Stripe Connect) for application/listing fees, buyer deposits, disbursements
• Notifications: Knock (in-app + email feed); Twilio for SMS
• KYC/Compliance: Persona (buyers & high-value sellers)
• Bank Linking: Plaid (ACH, verification)
• eCom Integrations (MVP): Shopify (Admin API + OAuth + webhooks)
• Email: Resend/Postmark/SendGrid (pick one and wire it cleanly)
• Search (MVP): Postgres FTS; plan to swap in Typesense/Algolia later
• Jobs/Workflows: Inngest or Trigger.dev (background tasks, webhooks, report generation)

4. Buyer Flow
   • Buyer signup → Persona KYC → optional small Stripe deposit to unlock details
   • Request Info / Inquire → route to seller via in-app thread + email/SMS
   • Basic message thread (realtime) between buyer & seller (mask emails)
      
5. Payments
   • Stripe application/listing fee for sellers (one-time)
   • Optional buyer deposit/intent fee to unlock confidentials

What Success Looks Like (30/60 Days)
 

• Day 30:
  • Seller valuation → draft listing → publish → appears in marketplace
  • Buyer signup → Persona KYC → deposit → gated unlock works
  • Inquiries/messages functional; notifications live; admin approve flow
