Job Description
The Opportunity: Join Apex Protocol Labs, a trailblazing force in the decentralized finance (DeFi) ecosystem. We are seeking a visionary Senior Smart Contract Engineer to architect the next generation of high-speed, secure blockchain infrastructure. If you are passionate about cryptography, scalable systems, and building the future of money, this is your stage.
Why Join Us?
- Work with state-of-the-art technologies in a fully remote-first environment.
- Competitive compensation package including equity options.
- Contribute to protocols with billions in Total Value Locked (TVL).
We are looking for a technical expert who can bridge the gap between theoretical cryptography and production-grade code.
Responsibilities
- Design, develop, and audit high-security smart contracts primarily in Solidity, with opportunities to contribute to Rust or Move-based chains.
- Optimize gas consumption and improve transaction throughput for Layer 2 solutions.
- Lead code reviews and implement rigorous testing strategies (unit, integration, and fuzz testing).
- Collaborate with the frontend team to integrate Web3 libraries (ethers.js, web3.js) into user-friendly interfaces.
- Identify and mitigate potential security vulnerabilities in smart contract code.
- Contribute to the technical roadmap for upcoming protocol upgrades and feature releases.
Qualifications
- 5+ years of professional software engineering experience, with at least 2 years specifically in blockchain development.
- Deep expertise in Solidity and the Ethereum Virtual Machine (EVM).
- Experience with Rust or Go is highly preferred.
- Strong understanding of cryptographic principles, hash functions, and zero-knowledge proofs.
- Proven track record of deploying and maintaining production-grade smart contracts on Ethereum or similar networks.
- Excellent problem-solving skills and ability to thrive in a fast-paced, agile environment.
