Company Description

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)

For strong performers: the opportunity to become a long-term external contributor for future short-term smart contract projects

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 bug bounty submissions and prepare initial assessments for core developers
