Job Description
We are building the infrastructure for the decentralized economy of 2026. As a Senior Web3 Engineer at Nexus Future Labs, you will architect the core protocols powering our next-generation ecosystem. We are looking for a visionary technologist to bridge the gap between complex cryptographic theory and scalable, user-friendly applications.
Join a team of world-class engineers, security auditors, and visionaries committed to pushing the boundaries of what is possible on the blockchain.
What You'll Do:
- Design and implement secure, high-performance smart contracts using Solidity and Rust.
- Optimize gas efficiency and transaction throughput for Layer 2 scaling solutions.
- Integrate complex off-chain data feeds using oracles and GraphQL.
- Conduct rigorous security audits and fuzz testing of deployed contracts.
- Collaborate with the frontend team to deliver seamless Web3 user experiences.
Qualifications:
- 5+ years of experience in backend development, cryptography, or distributed systems.
- Deep expertise in the Ethereum Virtual Machine (EVM) and consensus mechanisms.
- Experience with testing frameworks such as Hardhat, Foundry, or Chai.
- Strong understanding of cryptographic principles (Zero-Knowledge Proofs, Merkle Trees).
- Familiarity with TypeScript, Node.js, and modern frontend frameworks.
Responsibilities
- Develop and audit high-security smart contracts using Solidity and Rust.
- Integrate off-chain data with on-chain logic using oracles.
- Optimize gas fees and transaction throughput for dApps.
- Collaborate with product managers to define technical roadmaps.
- Contribute to the design of cross-chain interoperability protocols.
Qualifications
