Full-Stack Web3 Engineer

About our client

Copiapoa Technologies Inc is a brand-new, venture-backed product studio founded by a pair of repeat founders who previously built and exited a company funded by Sequoia Capital, Founders Fund, Spark Capital, and others.

Their new chapter is funded by Thrive Capital and Variant Fund. They are shipping crypto-native products that marry rock-solid UX with on-chain composability, and they treat AI as a default teammate-every workflow in their day to day is augmented by the latest LLM tooling.

They are still small (

What You'll Work On

• End-to-end product features: TypeScript / React / Next.js front-ends that feel instant and delightful.
• Smart-contract & program logic on Solana (Anchor / Rust).
• Green-field architecture decisions: infra, CI/CD, observability, security, performance.
• Optionally: mobile surfaces in React Native and rapid-prototyping in Figma.

You'll pair directly with the founders, design, and product to push code to prod within days of joining.

Must-Haves

• Familiarity with crypto/Web3 fundamentals (wallets, signing, RPCs).
• Comfort using AI coding copilots (Cursor, Claude Code, etc.) / prompt engineering in daily workflow.
• Strong communication-clear PRs, thoughtful architecture docs, async-friendly mindset.

Nice-to-Haves

• Anchor-framework chops on Solana mainnet.
• React Native or Expo for mobile.
• Pixel-perfect UI / motion design streak (Figma, CSS-in-JS, Tailwind).
• Prior startup or open-source maintainer experience.
