Founding Fullstack Engineer

Index Network
New York, NY

We're building the protocol for private, intent-driven discovery, where agents work on your behalf, match you with the right people, and coordinate actions based on unstructured signals like curiosity, goals, and timing. Think programmable introductions, reputation-driven matching, and context-aware ambient discovery.

Now, we're looking for a Founding Fullstack Engineer to help us push that vision forward. You’ll be shaping the architecture of both our frontend and backend, building systems that integrate into real-world social protocols. You'll prototype fast, test with real users, and iterate in the wild.

Tasks

  • Building and scaling our Next.js + React frontend (with Tailwind, Radix UI, and Ant Design)
  • Designing and implementing Express + TypeScript APIs backed by Postgres (via Drizzle ORM) and Redis
  • Prototyping real-time, event-driven features that support intent-driven discovery
  • Developing SDKs and services that external developers can use

Requirements

  • Have 3+ years of hands-on TypeScript experience across frontend and backend
  • Strong with Next.js/React (hooks, state, performance, component design)
  • Solid backend experience with Express, Postgres (SQL/ORMs), and Redis
  • Comfortable with DevOps basics (Docker, CI/CD, cloud infra like AWS)
  • Proficient with Git, Unix, and modern dev environments
  • Thrive in fast-paced, ambiguous environments and love shipping quickly

Benefits

  • Competitive pay & real ownership - Salary plus meaningful equity.
  • Health, dental, vision - Solid coverage so you can focus on building, not bills.
  • Flexible time & location - We’re NYC-based but work how and where we’re most effective.
  • Gear + growth budget - Get the setup and learning resources you need.
  • Tight, early team energy - Low ego, fast feedback, and a lot of shared momentum.

We're early, fast, and a little wild. If that sounds like your speed, we'd love to talk.
