Binance Accelerator Program - Software Engineer (Backend + AI/LLM)

About the Role
We are seeking a Senior Solidity Engineer to design, develop, audit, and optimize high-performance smart contracts on Ethereum and EVM-compatible chains. As a senior contributor, you will lead critical protocol development, mentor junior engineers, and ensure our on-chain systems are secure, gas-efficient, scalable, and production-ready in a fast-moving Web3 environment.
Key Responsibilities
Architect and implement complex smart contracts using Solidity for DeFi protocols, NFTs, governance systems, bridges, oracles, and other blockchain primitives.
Conduct thorough security reviews, formal verification where applicable, and collaborate with external auditors.
Optimize contracts for gas efficiency, security, and maintainability.
Integrate smart contracts with front-end applications, off-chain services, indexing solutions (The Graph, Subsquid), and cross-chain infrastructure.
Develop and maintain comprehensive test suites (unit, integration, fuzzing, and invariant testing).
Participate in code reviews, architectural decisions, and technical roadmap planning.
Mentor mid-level and junior engineers on best practices, security patterns, and Solidity internals.
Monitor deployed contracts, respond to incidents, and implement post-deployment upgrades (via proxies where applicable).
Stay current with EVM upgrades (e.g., Prague/Electra), L2 scaling solutions (Optimism, Arbitrum, zkSync, etc.), and emerging standards (ERC-xxx, Account Abstraction).
Required Qualifications (Must-Have)
1-3 years of professional experience in Solidity development with a proven track record of deploying secure, audited smart contracts to mainnet.
Deep mastery of Solidity (v0.8.x+), including advanced patterns (reentrancy guards, upgradeable proxies – UUPS/Transparent, diamond pattern, libraries).
Strong understanding of EVM internals, gas optimization techniques, and security vulnerabilities (SWC registry, common attack vectors).
Proficiency with smart contract testing frameworks: Foundry (preferred) or Hardhat + ethers.js/waffle.
Experience with formal verification tools (Certora, Slither, MythX) and static analysis.
Solid experience in at least one major Web3 domain: DeFi (AMM, lending, derivatives), NFTs/marketplaces, RWA, or infrastructure (bridges, account abstraction).
Strong TypeScript/JavaScript skills for tooling and integration.
Experience working with Layer 2 solutions and cross-chain messaging protocols.
Excellent written and verbal communication skills; ability to write clear technical documentation (NatSpec, architecture decision records).
Track record of contributing to open-source projects or public GitHub repositories (please share links).
Preferred Qualifications (Strong Plus)
Previous experience at a top-tier Web3 protocol, audit firm (e.g., Trail of Bits, OpenZeppelin), or high-profile DeFi project.
Knowledge of Rust or other languages for blockchain development (bonus for familiarity with zk-proofs or Move).
Experience with Account Abstraction (ERC-4337), intent-based architectures, or MEV mitigation.
Familiarity with governance frameworks (Governor, Tally) and tokenomics design.
Contributions to standards (EIPs) or participation in Ethereum core dev calls.
Security researcher background or history of responsible disclosure.
What We Offer
Competitive compensation (base + significant token equity).
Fully remote-friendly with flexible hours.
Opportunity to work on cutting-edge blockchain infrastructure with real user impact.
Budget for conferences, security tooling, and continuous learning.
