Are you energized by building interfaces that shape how future societies organize, govern, and connect?
Do you want to work at the frontier of Web3, community platforms, and next-generation digital–physical experiences?

Join one of the world's fastest-growing network societies — a movement designing the governance, technology, and infrastructure for the communities of tomorrow.

About Us

We are scaling rapidly and building the systems that will power a new model of interconnected global communities. Our growth is accelerating: double-digit month-over-month expansion, new hubs launching worldwide, and a bold long-term vision of millions of engaged citizens connected through a shared digital backbone.

To achieve this, we're building:

A next-generation governance platform — reimagining how collective decision-making works, powered by AI
A robust community OS — subscriptions, events, payments, directories, referrals, and more
Deep Web3 integrations — blockchain credentials, wallet auth, crypto-native tooling
A physical–digital bridge — linking real-world access to blockchain-backed identity
Integrated co-living experiences — blending offline spaces with digital infrastructure
A vibrant global community — talented, diverse, and eager to build the future with us

This is the environment: ambitious, experimental, fast-moving, and deeply mission-driven.

Why You'll Want to Work Here

True frontier technology: You'll build at the edges of governance, identity, and community tech.
Crypto-native ecosystem: Many of our supporters and users are influential leaders shaping the future of Web3.
Early-stage momentum: Our platform is live, our communities are growing, and yet we're still early enough that your impact will be foundational.

The Role: Senior Frontend Engineer

We're looking for a Senior Frontend Engineer to help architect and build our PWA and community platform using Qwik, , and React. You will own major pieces of the frontend stack — from performance optimization to complex state management — and work closely with the CTO and backend team. You'll also use modern AI coding tools to ship high-quality features quickly.

This role is perfect for someone who writes elegant, fast, delightful interfaces — and wants to help build the digital foundation for future societies.

What You'll Do

Architect, develop, and optimize core frontend systems
Build high-performance UIs with exceptional UX and responsiveness
Own complex state management and rendering behavior
Collaborate closely with backend engineers and leadership
Use AI tooling to accelerate development without compromising quality

What We're Looking ForMust-Have Experience

5+ years of professional frontend engineering
Expert-level React (hooks, context, rendering patterns, performance tuning)
Strong knowledge (App Router, Server Components, data fetching)
Deep comfort with TypeScript (complex types, inference, generics)
Proven ability to build beautiful, fast, reactive, user-delightful interfaces

Highly Valued

Web3 familiarity — wallets, transactions, MetaMask usage
Experience with wagmi/viem and modern Web3 libraries
Background in design systems or component libraries
