Job description

We're partnering with an early-stage, NYC-based consumer social startup on their first technical hire - a founding engineer who'll shape the product, the systems, and the engineering culture from day one alongside the founders.

They just closed pre-seed, have a passionate beta community, and are about to go to market. This is a true zero-to-one seat with a clear path toward technical leadership as the team grows.

What you'll do

  • Own large, ambiguous problems and ship them end-to-end across frontend, backend, and infra
  • Architect core systems - real-time feeds, search, chat, browsing
  • Build ML-intensive features (semantic search, embedding pipelines, vector indexing, automated tagging with off-the-shelf models)
  • Set technical standards as the codebase and team scale
  • Partner directly with founders on product and technical strategy

Requirements

  • Experience shipping production-grade software end-to-end
  • Comfortable moving across frontend, backend, and infra
  • Hands-on with modern ML/AI in production (you don't need to be a researcher - just fluent in the stack)
  • A strong bias for action and a lot of agency
  • Bonus: you're genuinely tapped into pop culture, creative tools, and the future of the social web
  • Bonus: you've used AI coding tools like Claude Code, Cursor, Windsurf, or Codex

Stack: TypeScript, Serverless Postgres (Neon), React Router v7, Drizzle ORM, Cloudflare R2, Fly.io. You don't need every tool - just the ability to ramp fast.

Benefits & conditions

  • ???? $150K-$200K base + meaningful founding-level equity
  • ???? On-site
  • ???? Health, dental, vision * flexible PTO * offsites + access to NYC's creative scene
