Smart Contract Support Engineer (EVM/API Expansion)

We are looking for a Smart Contract Support Engineer to help maintain, expand, and enhance a large-scale multi-chain smart contract ecosystem within the EVM/API expansion team.

This role supports a leading cross-chain liquidity and bridging protocol that is scaling its smart contract infrastructure, currently operating 1500+ production contracts across 60+ EVM chains and several non-EVM environments. You will contribute to multi-chain deployments, bridge integrations, infrastructure improvements, and the automation of developer tooling as the ecosystem continues to grow.

The position focuses on supporting and extending the organization’s EVM-based smart contract infrastructure, including:
- Supporting the internal EVM/API expansion smart contract team
- Owning and delivering non-security-critical engineering tasks (no deployer key or multisig access required)

Requirements

• Strong experience with Solidity, TypeScript, and ideally bash scripting (approx. 3–5 years)
• Proficiency with Foundry (testing, deployment, debugging)
• Ideally: experience with many-chain deployments and bridge/DEX protocols
• Experience collaborating with external auditors or participating in audit preparation

Responsibilities

Multi-Chain Deployment Improvements

• Enhance bash scripts orchestrating multi-/many-chain deployments (including parallelization across 10+ chains)
• Ensure automatic contract verification works across all supported networks
• Assist in upgrading the codebase to the latest Foundry version

Bridge Integrations

• Research, evaluate, and document new bridge protocols
• Implement new facet or periphery contracts
• Collaborate with core engineers on reviews, testing, and production readiness

Smart Contract Enhancements

• Extend or modify existing contracts (e.g., new mappings, parameters, or functionality)
• Ensure modifications follow internal coding, security, and quality standards

Audit Preparation & Coordination

• Prepare and finalize PRs for external smart contract audits
• Communicate with auditors where needed and provide proposed resolutions for identified issues

Tooling & Automation

• Maintain and improve deployment and verification scripts across 60+ EVM chains
• Adjust and enhance GitHub CI/CD to support multi-chain workflows

Transaction & Bug Analysis

• Investigate failed on-chain transactions and provide initial diagnostics
• Review
