React Web3 Jobs in United States

This *** All Star Founding Team *** backed by some of the biggest names in the internet 👀 👀👀 is building something ambitious at the edge of consumer finance and predictive markets. Still under the radar, but already backed by industry heavyweights with $12M pre-seed funding, we’re assembling a founding engineering team to take this from 0 → 1.

If you’ve ever wished you could have joined early at the likes of OpenSea, Robinhood Crypto, or Coinbase — this is that moment.

What you’ll be doing

• Architecting and building the core systems of a next-gen trading & prediction platform
• Working hands-on with Go (Golang) for backend services and Solidity for smart contracts
• Experimenting rapidly, iterating on prototypes, and scaling what works
• Designing for high performance, security, and reliability from day one

Tech stack you’ll touch

• Core: Go, Solidity, TypeScript
• Smart contract tooling: Hardhat, Foundry
• Infra: AWS / GCP, Kubernetes, Docker, Terraform
• Data & scaling: Postgres, Redis, Kafka, real-time event streams
• Frontend: React, Next.js, Web3 libraries (ethers.js, wagmi)
• Testing & DevOps: CI/CD pipelines, monitoring, on-chain testing frameworks

What we’re looking for

• Deep experience in Go (backend) and Solidity (Ethereum smart contracts)
• Track record building in high-volume or mission-critical environments
• Comfortable operating in a high-ambiguity, high-experimentation 0→1 setting
• Strong fundamentals in distributed systems, consensus, and/or cryptography a plus
• Curiosity and grit — you’ll be solving problems no one has fully solved before

Logistics

• Work primarily in EST timezone
• Open to candidates across the Americas and Europe
• Competitive comp + meaningful equity

This is your chance to shape the foundations of a product at the frontier of finance and crypto — while working alongside a founding team with the backing and credibility to win.

If you’re ready to build where the future of finance meets predictive markets, we’d love to talk.
