2d • Remote

About The Position

Injective Labs is seeking an accomplished Chain Engineer with a security focus to join its global protocol team. The role builds and hardens the core of the Injective chain, ensuring modules, upgrades, and integrations are secure before reaching mainnet. The engineer works alongside protocol engineers from specification through release, reviews designs for attack vectors, audits native chain code and EVM contracts, and develops tooling to maintain chain security. The position calls for autonomous work, strong ownership, and an attacker-minded approach to engineering.

Requirements

• At least 3 years of experience as a Blockchain Engineer, with a significant focus on security.
• At least 5 years of experience in software security.
• Hands-on experience auditing DeFi protocols or blockchain core code, internally or externally, with findings the candidate can discuss.
• Proficiency in Golang and/or Solidity.
• Strong knowledge of Go idioms, libraries, and parallel processing, as well as security pitfalls common in Go and Cosmos-SDK chains, including non-determinism, panics, unbounded iteration, gas, and denial-of-service issues.
• Strong knowledge of blockchain, DeFi and DEX concepts, consensus mechanisms, and the CosmWasm contract platform.
• Understanding of cryptographic primitives, including digital signatures and hash algorithms used by Ethereum and Cosmos.
• Ability to write clear security reports and explain risk to technical and non-technical team members.

Nice To Haves

• A track record in bug bounties, CTFs, or published audits and CVEs.
• Experience with fuzzing and formal verification tools.
• Prior experience working in trading or at an exchange.
• Knowledge of financial instruments and markets.

Responsibilities

• Conduct internal security audits of Injective Cosmos-SDK modules, including its decentralized orderbook, trade execution coordinator, order matcher, and Layer-2 execution environment.
• Review and audit EVM smart contracts, EVM integrations, cross-chain bridges, and IBC components.
• Partner with senior protocol engineers to incorporate security into new chain features from the outset and threat-model technical and economic risks, including oracle manipulation, MEV, liquidation, and market-manipulation attacks.
• Build, maintain, test, and directly secure core chain components, including consensus, state management, and financial infrastructure.
• Develop security tooling, including fuzzers, invariant and property-based tests, static analysis, and on-chain monitoring and alerting.
• Review chain upgrades and pull requests for determinism, consensus safety, denial-of-service vectors, and state-machine correctness.
• Write clear internal and public security reports and coordinate with external auditors, bug bounty researchers, and partners on findings and disclosure.
• Participate in incident response and lead post-mortems and remediation when issues arise.
• Research blockchain exploits and security developments and share learnings with the wider team.

Benefits

• Competitive salary and INJ token award.
• Remote-friendly work environment with flexible hours.
• Unlimited PTO.
• Equipment.
• Home office stipend.
• Opportunity to work on cutting-edge blockchain technology in the finance industry.
• Collaborative team culture with opportunities for professional growth and development.
• Global team meetups.
