Open roles

feat. is where creators and brands publish co-branded collab pages—AI-generated from brand kits and creator identity—with programs that fan out to whole rosters, calendar integrations, audiences and attribution, and usage-based billing. We’re a small team shipping that MVP end to end.

Senior Full Stack Engineer

Full-time · Remote

We’re looking for a Senior Full Stack Engineer who can own features end-to-end from API to UI for this MVP: co-branded creator × brand collab pages, AI-assisted generation from kits, brand roster fan-out and program versioning, calendar-style integrations, the Audiences and attribution surfaces, and usage-based billing.

Responsibilities

  • Ship core product flows in Next.js/React: New funnel (role-aware partner URL, solo post, brand roster fan-out), live merge preview, My pages (creator gallery vs brand programs + add-versions).
  • Build and evolve REST APIs for funnels/programs (create-program, add-versions), integrations (e.g. saved calendar booking link), and Audiences aggregates.
  • Implement the collab editor: template-first fields for built-in page types; sandboxed iframe rendering, inline parameter tagging, and replication paths for uploaded HTML/CSS templates.
  • Integrate AI/LLM flows for generating and rewriting co-branded page copy from brand + creator kits.
  • Model and query MongoDB for funnels, leads, funnel events, programs/version metadata, and attribution (including per-channel UTM links).
  • Ship billing limits and upgrade paths aligned with usage-based pricing (free tier caps, Stripe payment links / plan upgrades).
  • Keep auth sessions, APIs, and user-generated template rendering secure and observable as we iterate.

Required skills

  • Strong experience with Next.js (App Router), React, and TypeScript.
  • Backend and API design in Node.js (REST, validation, clear error contracts—e.g. limit enforcement responses).
  • Experience with MongoDB (documents that back funnels, leads, and event streams).
  • Stripe or similar for subscriptions / payment links tied to plan tiers.
  • Solid auth patterns (sessions, magic links, multi-persona accounts).
  • Comfort wiring AI/LLM APIs into production flows (generation, rewrite-in-editor).
  • Proficiency with Tailwind CSS and responsive, accessible UI.
  • Solid Git workflow, testing habits, and production debugging.

Nice to have

  • Secure rendering of user-supplied markup (iframe sandboxing, CSP, asset paths).
  • Prompt and structured-output patterns for template-driven page generation.
  • Product analytics or event pipelines (funnel events, attribution dashboards).
  • Deployment on Vercel or similar.
  • Two-sided creator × brand or marketplace-adjacent products.
