Blockchain Engineer (Bucharest-Remote)

At Token Metrics, a Blockchain Engineer focuses on developing smart contracts and blockchain solutions to enhance our platform. This includes designing, implementing, and testing EVM smart contracts for various projects like cross-chain bridges, ensuring that the implemented solutions are secure and efficient.

To qualify for the Blockchain Engineer role at Token Metrics, candidates should have over 3 years of software engineering experience or equivalent blockchain/smart contract development experience. Proficiency in Solidity and understanding smart contract security are essential, along with experience in deploying projects in a production environment.

To apply for the Blockchain Engineer position at Token Metrics, you should submit your resume along with a cover letter that highlights your relevant skills and experience in blockchain development. Be sure to showcase any projects you've worked on that align with the responsibilities of this role.

As a Blockchain Engineer at Token Metrics, you'll engage in a variety of projects that highlight your skills in smart contract development. Expect to work on creating infrastructure for asset movement through cross-chain bridges and implementing Solidity smart contracts for private transactions.

Token Metrics fosters a collaborative and innovative culture, encouraging Blockchain Engineers to engage with their peers. The company values creativity and supports flexible working arrangements, making it an exciting place where your ideas can flourish.

In your role as a Blockchain Engineer at Token Metrics, you will primarily use Solidity for smart contract development. You will also work with various tools for testing and deploying smart contracts, including frameworks like Truffle and Hardhat, as well as interact with dapps and the broader web3 ecosystem.

Token Metrics takes smart contract security seriously by working closely with external auditors to evaluate our contracts. This ensures that we adhere to best practices and identify any vulnerabilities before deploying our smart contracts.

When designing an EVM smart contract, it's essential to start by clearly defining the smart contract's purpose and requirements. I prioritize creating a robust architecture, and then I write, optimize, and rigorously test my code, ensuring it meets all security standards.

Smart contract security best practices include proper access controls, using established libraries, conducting thorough testing, and engaging with third-party auditors. It's vital to avoid common pitfalls such as reentrancy vulnerabilities and ensuring that contract logic is accurate.

I have extensive experience with dapps in the web3 ecosystem, including developing user-facing features that interact with smart contracts. I focus on ensuring seamless integration and enhancing the user experience while maintaining security and efficiency.

To ensure timely delivery, I prioritize effective communication and active collaboration with the product and engineering teams. I also break down projects into manageable milestones and regularly review our progress to stay on track.

One challenging project involved building a cross-chain bridge that required extensive testing to ensure all assets were transferred securely and efficiently. I learned that thorough testing and iterations are key to success when handling complex operations.

External audits are crucial in my development process to ensure the security of smart contracts. They provide an objective review of my code, identify potential vulnerabilities, and help validate that I adhere to best practices before deployment.

I employ both unit testing and integration testing to validate my smart contracts before deployment. This involves simulating various scenarios and edge cases to ensure that the contracts behave as expected in different situations.

I have a solid understanding of Solidity precompiles, as they provide optimized operations that can significantly improve performance. Leveraging these can reduce execution costs and enhance the efficiency of smart contracts.

I stay informed about the latest trends and security vulnerabilities in blockchain by following reputable resources, participating in webinars, and engaging with the developer community. Continuous learning is essential in this rapidly evolving field.

I'm excited about the opportunity to work as a Blockchain Engineer at Token Metrics because of the company's commitment to innovation in crypto investment. I admire the use of AI for portfolio management and am eager to contribute to creating impactful solutions in this space.
