We’re looking for an exceptional Protocol Engineer to help us push the frontier of blockchain interoperability. You’ll focus on the on‑chain layer of the Metalayer—Caldera’s high‑performance, stack‑agnostic bridge that already serves 75+ rollups and their users.
Your day‑to‑day will involve architecting and hardening smart contracts that move real value across chains, designing security‑critical role and upgrade patterns, and collaborating with audit partners to ship code that can safely secure hundreds of millions of dollars.
This is the perfect role for an engineer who has shipped high‑TVL protocols and thrives on digging deep into EVM/SVM internals, gas economics, and cross‑chain message‑passing. If you want to see your work deployed to dozens of chains and used by thousands of developers, we’d love to meet you.
We’re backed by leading crypto investors (Founders Fund, Dragonfly, and Sequoia), offer competitive cash + token, and provide full benefits.

• Have 3+ years engineering experience, including shipping production protocols with significant TVL.
• 
  Possess expert‑level Solidity and/or Rust skills and a deep grasp of EVM/SVM internals.
• 
  Understand gas/compute metering on Ethereum, L2s, and Solana, and how off‑chain components (relayers, indexers) interact with contracts.
• 
  Are comfortable owning end‑to‑end security: access control, upgradeability, failure‑mode analysis, and incident response.
• 
  Excel at systematic debugging, test‑driven development, and writing clean, well‑reviewed code.
• 
  Communicate clearly and enjoy partnering with frontend, backend, and product teams.
