Requirements

Proven Independent Smart Contract Development: Demonstrable experience of independently designing, building, testing, deploying, and thoroughly understanding small to medium-sized smart contract systems on EVM/SVM-based blockchains. Also, be able to articulate the design choices, trade-offs, and security considerations of projects you've built end-to-end.

Deep Understanding of Token Handling Mechanisms: Extensive, hands-on experience with various token standards and complex token interactions.

Experience with Token Pools or Similar Financial Primitives: Verifiable experience in designing, implementing, or significantly contributing to on-chain token pools, liquidity pools, escrow contracts, vault contracts, or similar financial primitives that involve managing and transferring tokenised assets.

Proficiency in Solidity: Strong and hands-on experience in smart contract development using Solidity and/or Rust, including knowledge of common patterns, security pitfalls, and gas optimisation techniques.

General Blockchain & EVM Knowledge: Solid understanding of core blockchain concepts, EVM/SVM architecture, transaction lifecycle, and smart contract execution environments.

Problem-Solving & Autonomy: Ability to independently troubleshoot complex on-chain issues, debug smart contracts, and drive technical tasks to completion with minimal supervision.

Smart Contract Security Best Practices: Strong understanding of common smart contract vulnerabilities and how to mitigate them.

Smart Contract Development Tools & Testing Frameworks: Experience with tools like Hardhat, Foundry, Truffle or Anchor for development, testing, and deployment.

Smart Contract Upgrade Patterns: Familiarity with various smart contract upgradeability patterns

Off-Chain Scripting/Interaction: Experience writing scripts (e.g., using Typescript/Javascript with Ethers.js/Web3.js, or GoLang) to interact with and manage smart contracts.

CI/CD for Smart Contracts: Experience with continuous integration and continuous deployment pipelines for smart contracts.

Understanding of Distributed Systems Principles: A good grasp of concepts relevant to building and interacting with distributed systems.

Responsibilities

Designing and Implementing CCIP-Integrated Smart Contracts: Independently own the development and deployment of custom smart contracts that interact with CCIP, including token pool contracts and other on-chain logic required for specific partner use cases. This involves a deep understanding of token handling (minting, burning, locking, unlocking, wrapping) and ensuring secure asset management.

Developing Reusable On-Chain Patterns: Create and refine standardised smart contract templates, libraries, and deployment patterns specifically for CCIP use cases to accelerate partner integrations and ensure best practices are followed.

End-to-End Project Ownership: Independently manage the full lifecycle of small to medium-sized on-chain development tasks, from initial requirements gathering and technical design through to rigorous testing, deployment, and post-deployment support.

Security and Optimisation: Prioritise smart contract security throughout the development process, implementing best practices, conducting thorough testing, and optimising for gas efficiency. You'll also contribute to defining secure upgrade strategies for deployed contracts.

Collaboration: Work closely with Solutions Architects, Product Managers, and other Engineering teams to translate partner requirements into robust on-chain solutions. You'll also provide technical guidance to partners on integrating with the smart contracts you build.

Technical Documentation: Produce clear and comprehensive technical documentation, including deployment guides and integration instructions, for the smart contracts and on-chain systems you develop.
