Our protocol interacts with energy hardware in the real world and tokenizes the value of flexible energy capacity into crypto-native incentives-bridging digital and physical infrastructure through verifiable smart contracts, oracles, and data integrations. You should bring deep experience in Solidity and DeFi architectures (especially stablecoins, lending, or reward mechanisms), and be comfortable deploying cross-chain smart contracts using modern interoperability protocols like LayerZero or Wormhole. You should also be confident designing systems that ingest and act on offchain data in a trust-minimized way-whether through Chainlink, Chronicle, or custom oracle networks. We're a small team working quickly, so you should be comfortable jumping into backend tasks when needed-whether supporting our Django APIs or refining the interface between our offchain services and smart contract layer. This is a high-impact, high-ownership role. You'll work directly with the founding team, shaping the cryptoeconomic and technical foundation of Daylight's protocol. This role is in-person in our New York City office. Responsibilities * Protocol Development + Design and implement Solidity smart contracts that underpin Daylight's decentralized energy markets + Lead architecture decisions for our EVM-based systems across mainnet and L2s + Manage crosschain deployments and integrations using LayerZero, Wormhole, or similar technologies + 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 to bridge between energy hardware, APIs, and contracts + Design and maintain trust assumptions, verification mechanisms, and upgrade paths * Backend Engineering + Support Daylight's core backend team as needed with Python/Django development + Help design and maintain APIs that interact with contracts and power our 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 crosschain architecture * Product Strategy & R&D + Contribute to protocol incentive design, economic modeling, and simulations + Evaluate new technologies, frameworks, and cryptoeconomic primitives to inform ## Related Videos - [Blockchain, NFT and smart contracts for my application](https://www.wearedevelopers.com/videos/877-blockchain-nft-and-smart-contracts-for-my-application) - [Trust as the Key Concept in Future Mobility](https://www.wearedevelopers.com/videos/581-trust-as-the-key-concept-in-future-mobility) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [​Road to Web3](https://www.wearedevelopers.com/videos/584-road-to-web3) - [DevOps Maturity Check – a way to balance autonomy and alignment](https://www.wearedevelopers.com/videos/58-devops-maturity-check-a-way-to-balance-autonomy-and-alignment) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 138 - Are you secure about this?](https://www.wearedevelopers.com/magazine/486-dev-digest-138-are-you-secure-about-this) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [The Best X (Twitter) Accounts for Developers](https://www.wearedevelopers.com/magazine/294-the-best-x-twitter-accounts-for-developers) - [From Hype to Code: Real Blockchain Use Cases for Developers](https://www.wearedevelopers.com/magazine/620-from-hype-to-code-real-blockchain-use-cases-for-developers)
