Blockchain Engineer

About Aeons
AEONS is building a venture studio designed to move ideas from thesis to working products.
Our Launch Engine is a shared team of engineers, designers, researchers and distribution specialists that works across new ventures in areas including blockchain infrastructure, tokenization, financial technology and emerging digital systems.
We are deliberately building a young, hands-on team. We care less about inflated titles and more about whether you can think clearly, build well, learn quickly and take responsibility for what reaches production.
The role
We are looking for a Blockchain Engineer with strong smart-contract fundamentals to join the core technical team of the AEONS Launch Engine.
You will work alongside our Full-Stack Engineer, AI/ML Engineer and Product Designer to prototype, test and deploy blockchain-enabled products across the AEONS portfolio.
This is not a role for someone who only wants to write isolated Solidity contracts.
You should be interested in the complete system around them: wallets, permissions, token logic, APIs, indexing, testing, security, off-chain services and the user experience through which blockchain infrastructure becomes an actual product.
What you will work on
• Design and implement smart contracts for real products and prototypes.
• Build primarily with Solidity / EVM-compatible infrastructure, while remaining open to other chains where product requirements justify them.
• Develop token, wallet, permission, settlement and on-chain interaction logic.
• Integrate contracts with front-end and back-end applications.
• Write rigorous unit, integration and invariant tests.
• Work with libraries and tooling such as Foundry, Hardhat, OpenZeppelin, ethers/viem or equivalent.
• Think carefully about access control, upgradeability, key management, oracle dependencies and common smart-contract attack surfaces.
• Review contracts written by other engineers and participate in technical design reviews.
• Build prototypes quickly without allowing prototype habits to become production security standards.
• Document important architectural decisions so another engineer can understand why the system was built the way it was.
• Work across different AEONS ventures rather than being locked permanently into a single product.
You do not need ten years of experience. Rather, we want evidence that you can build. Apply by clicking on the LinkedIn apply button and uploading your CV.
