Protocol Engineer

We're looking for an exceptional Protocol Engineer to help us push the frontier of blockchain interoperability. You'll focus on the onchain layer of the Metalayer -Caldera's 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, 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.

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. We're 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 Metalayer's surface area.
