Were looking for an exceptional Protocol Engineer to help us push the frontier of blockchain interoperability. Youll focus on the onchain layer of the Metalayer Calderas highperformance, stackagnostic bridge that already serves 75+ rollups and their users.
Your daytoday will involve architecting and hardening smart contracts that move real value across chains, designing securitycritical 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 highTVL protocols and thrives on digging deep into EVM/SVM internals, gas economics, and crosschain messagepassing. If you want to see your work deployed to dozens of chains and used by thousands of developers, wed love to meet you.
Were backed by leading crypto investors (Founders Fund, Dragonfly, and Sequoia), offer competitive cash + token, and provide full benefits.
About Caldera
Caldera builds infrastructure that lets the most ambitious Web3 apps launch ultraperformant rollups instead of competing for block space on congested generalpurpose chains. Our software powers dynamic, scalable blockchain experiences for millions of users. Were a distributed team with hubs in San Francisco and New York , and we support both inoffice and remote work.
As a Protocol Engineer at Caldera, you will
Design & implement Solidity and Rust smart contracts across EVM, L2s, and SVM that form the core Metalayer protocol.
Own onchain security rolebased access control, pause/upgrade paths, and highvalue asset protections.
Drive audits : spec, coordinate, and remediate findings with top security firms.
Collaborate with relayer, indexer, and frontend teams to define clear, developerfriendly onchain APIs.
Build tooling for onchain monitoring, alerting, and gas/performance profiling.
Research & prototype new protocol features (e.g., fastfinality bridges, ZKverified proofs) that expand Metalayers surface area.
You might be a fit for this role if you
Have 3+ years engineering experience, including shipping production protocols with significant TVL.
Possess expertlevel Solidity and/or Rust skills and a deep grasp of EVM/SVM internals .
Understand gas/compute metering on Ethereum, L2s, and Solana, and how offchain components (relayers, indexers) interact with contracts.
Are comfortable owning endtoend security: access control, upgradeability, failuremode analysis, and incident response.
Excel at systematic debugging, testdriven development, and writing clean, wellreviewed code.
Communicate clearly and enjoy partnering with frontend, backend, and product teams.
Bonus points
Prior experience building AMMs, bridges, or MEV/intents systems .
Handson work with consensus algorithms (Paxos/Raft, Tendermint, HotStuff, etc.).
Familiarity with ZK proofs, fastfinality research, or crosschain messaging standards (e.g., CCIP, IBC).
Significant opensource contributions to blockchain clients, protocol libraries, or security tools.
Compensation Range: $190K - $250K
