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 teammateevery workflow in their day to day is augmented by the latest LLM tooling.

They are still small (<5 people) but moving fast; every hire will shape the codebase, culture, and trajectory.

What Youll 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).
  • Optionally: mobile surfaces in React Native and rapid-prototyping in Figma.

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

  • 3+ yrs professional experience shipping user-facing software.
  • Fluency with React + Next.js (hooks, SSR/SSG, edge functions).
  • Working knowledge of Rust OR strong conviction to learn it quickly.
  • Familiarity with crypto/Web3 fundamentals (wallets, signing, RPCs).
  • Comfort using AI coding copilots (Cursor, Claude Code, etc.) / prompt engineering in daily workflow.
  • Strong communicationclear PRs, thoughtful architecture docs, async-friendly mindset.
  • Anchor-framework chops on Solana mainnet.
  • React Native or Expo for mobile.
  • Prior startup or open-source maintainer experience.

Why Join Them

  • Founders with proven execution & exits. They know the zero-to-one grind and how to scale.
  • Backed by top-tier crypto & fintech VCs runway to take big swings, not incremental bets.
  • Ownership that matters. Competitive salary + meaningful equity early in the cap table.
  • Hybrid flexibility. Vibrant LA office for team jams; remote OK if overlapping ~4h with PST.
  • AI-native culture. Unlimited budget for the best tools.
  • Fast shipping, low process. Autonomy, direct access to users, and Friday demos that actually ship to prod.
  • Health, dental, vision, unlimited PTO, & off-sites (yes, they actually take them).

They value and hire really smart, really hungry people from all walks of life. If someone is excited about building the next generation of crypto consumer experiences, they encourage reaching out.
