Protocol Engineer - Remote

Overview

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.

In Short

• Design & implement Solidity and Rust smart contracts across EVM, L2s, and SVM that form the core Metalayer protocol.
• Own on‑chain security—role‑based access control, pause/upgrade paths, and high‑value asset protections.
• Drive audits: spec, coordinate, and remediate findings with top security firms.
• Collaborate with relayer, indexer, and frontend teams to define clear, developer‑friendly on‑chain APIs.
• Build tooling for on‑chain monitoring, alerting, and gas/performance profiling.
• Research & prototype new protocol features (e.g., fast‑finality bridges, ZK‑verified proofs) that expand Metalayer’s surface area.

Requirements

• 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.

Benefits

• Competitive cash + token compensation.
• Full benefits package.
• Support for both in‑office and remote work.
