Security Chain Engineer (Injective Labs)

Role overview

Help secure the core of a blockchain protocol by reviewing its code and designs, strengthening critical components, and addressing vulnerabilities before they reach production. The work spans chain modules, smart contracts, cross-chain integrations, security tooling, and incident response, in close collaboration with protocol engineers.

Responsibilities - Audit protocol modules, smart contracts, and bridge or inter-blockchain components for security flaws. - Threat-model new features for technical and economic attacks, including oracle manipulation, transaction ordering risks, and liquidation exploits. - Harden consensus, state management, and financial infrastructure, and fix identified vulnerabilities in the codebase. - Build and maintain fuzzers, property-based and invariant tests, static analysis, and on-chain monitoring. - Review upgrades and code changes for deterministic behavior, consensus safety, denial-of-service risks, and state-machine correctness. - Write security reports, coordinate findings and disclosure, and support incident response and post-incident remediation.

Requirements - At least 3 years of blockchain engineering experience focused substantially on security, and 5 or more years in software security. - Hands-on experience auditing DeFi protocols or blockchain core code, with concrete findings to discuss. - Proficiency in Go and/or Solidity; strong understanding of Go libraries, concurrency, and common security pitfalls in Go-based chains. - Knowledge of blockchain, DeFi and decentralized exchanges, consensus, and the CosmWasm contract platform. - Understanding of cryptographic primitives, digital signatures, and Ethereum and Cosmos hashing approaches. - Ability to explain security risks clearly to technical and non-technical audiences.

Nice to have - Bug bounty, capture-the-flag, published audit, or vulnerability disclosure experience. - Familiarity with fuzzing or formal verification, trading systems, exchanges, or financial markets.
