Protocol Engineer
Daylight · New York, NY
About this role
### About Daylight Daylight is the decentralized energy company building a protocol that converts distributed solar and storage systems into yield-bearing infrastructure. These assets are deployed behind the meter in American homes and businesses, generating electricity revenues that flow onchain as a single, liquid yield token. Backed by a16z, Framework Ventures, and other leading investors, Daylight is bringing together top minds in energy and crypto to build a transparent, decentralized energy network designed for the energy transition. Learn more: https://www.godaylight.com --- ### The Role (Protocol Engineer) As a Protocol Engineer at Daylight, you’ll lead development of core smart contracts and decentralized backend systems that underpin our onchain energy network. The protocol interacts with real-world energy hardware and tokenizes flexible energy capacity into crypto-native incentives—bridging digital and physical infrastructure through verifiable smart contracts, oracles, and data integrations. This is a high-impact, high-ownership role working directly with the founding team to shape the cryptoeconomic and technical foundation of Daylight’s protocol. **Location:** In-person in our New York City office. --- ### Responsibilities - **Protocol Development** - Design and implement Solidity smart contracts underpinning Daylight’s decentralized energy markets - Lead architecture decisions for EVM-based systems across mainnet and L2s - Manage cross-chain deployments and integrations (LayerZero, Wormhole, or similar) - Develop core logic for staking, token issuance, energy capacity verification, and rewards - **Data Integration & Oracles** - Architect secure offchain data flows to feed real-world energy data into onchain systems - Work with oracles and custom data infrastructure bridging energy hardware, APIs, and contracts - Design and maintain trust assumptions, verification mechanisms, and upgrade paths - **Backend Engineering** - Support core backend tasks as needed with Python/Django - Help design and maintain APIs that interact with contracts and power frontend applications - Participate in DevOps, testing, and deployment of protocol-related services - **Security & Auditing** - Lead internal security reviews and coordinate third-party audits of smart contracts - Stay up-to-date on known exploits and best practices in DeFi and cross-chain architecture - **Product Strategy & R&D** - Contribute to protocol incentive design, economic modeling, and simulations - Evaluate new technologies, frameworks, and cryptoeconomic primitives --- ### What We’re Looking For **Must Haves** - 3+ years developing and deploying Solidity smart contracts in production - Deep familiarity with DeFi protocols (stablecoins, lending markets, staking, or yield systems) - Cross-chain development experience (e.g., LayerZero, Wormhole, Axelar) - Proven experience integrating offchain data via oracles (Chainlink, Chronicle, custom feeds) - Understanding of EVM security, auditing practices, and gas optimization - Comfortable writing/reviewing Python and supporting traditional backend engineering tasks - Passion for clean energy, decentralization, and real-world impact - Based in NYC and excited to collaborate in-office **Nice to Haves** - Experience building L2-native or modular appchains (OP Stack, Polygon CDK, etc.) - Familiarity with protocol simulations (e.g., Python-based Monte Carlo models or token economic tools) - Prev
