Smart Contract Engineer

Chronicle Labs is looking for a Smart Contract Engineer to develop and secure EVM oracle contracts, analyze DeFi protocols, and support deployments and production systems.

You will develop, test, deploy, configure, and maintain EVM smart contracts for oracle systems. You will review contracts, support audits and upgrades, research EVM ecosystem changes, and document contract behavior and operational risks.

You will analyze DeFi protocols and translate their mechanics into reliable oracle data models and calculation logic. You will also support Go and Python tooling, deployments, production investigations, source integrations, security reviews, and technical documentation across on-chain and off-chain systems.

• Write, test, deploy, configure, and maintain EVM smart contracts for oracle systems
• Support deployments and upgrades across EVM chains and L2 environments
• Review smart contract changes for correctness, security, maintainability, and operational impact
• Support audit preparation, responses, remediation, and post-deployment checks
• Research chains, L2s, hard forks, EIPs, and EVM changes
• Build proof-of-concepts for on-chain components and move successful designs toward production
• Document contract behavior, assumptions, deployment steps, and operational risks
• Analyze DeFi protocols, vaults, pools, lending markets, staking systems, collateral models, and token accounting
• Translate protocol behavior into data requirements, assumptions, and calculation logic
• Identify edge cases and failure modes
• Support Proof of Asset and reconciliation methodology design
• Work with Go services, Python tooling, deployment scripts, and operational workflows
• Debug issues across contracts, APIs, data sources, transformation logic, and oracle outputs
• Support production readiness checks, configuration tracking, and deployment registers
• Apply security and applied cryptography principles to contracts, data models, and production systems
• Support internal reviews, audit evidence, customer security reviews, and institutional due diligence

• Strong practical experience with Solidity and EVM smart contracts
• Understanding of EVM internals, including storage, gas, calldata, events, and transaction execution
• Experience with Foundry or comparable smart contract tooling
• Strong computer science fundamentals
• Applied cryptography knowledge, including signatures, hashing, key exchange, key management, and common attack patterns
• Security-focused mindset and interest in smart contract review
• Understanding of DeFi mechanics, including pools, vaults, lending, staking, collateral, and token accounting
• Ability to translate protocol mechanics into data requirements and calculation logic
• Backend literacy with Go, Python, Rust, or similar tooling
• Ability to work independently and deliver within agreed timelines
• Clear written English and strong documentation habits
• Ability to reliably work with Central European working hours with strong CET/CEST overlap

• Equity participation
• Flexible payment options, including USD, EUR, and USDC
• 6 weeks vacation
• Flexible working schedule
• Annual company offsites

CV review; initial screening with Operations; interview with Engineering leadership; technical interview on on-chain experience, EVM knowledge, and smart contract reasoning; technical interview on security, cryptography, operations, and protocol analysis; identity and location verification for final-stage candidates.
