About Daylight

Daylight is the decentralized energy company. We're 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. Our ambition is to build the economic engine for energy abundance—where capital fuels power, and power fuels everything.

Our team brings together energy and crypto veterans who believe in a future where communities power themselves. Backed by a16z, Framework, and other industry-leading investors, we're building the infrastructure to make that vision a reality. Learn more at

The Role

As a Senior Software Engineer | Blockchain at Daylight, you'll play a crucial role in developing our Django APIs and backend services that support our mobile app and partner integrations as well as designing the interactions with our smart contracts onchain. You'll build functionality that helps homeowners monitor, control, and optimize their energy usage while participating in our decentralized energy network.

We're an early-stage startup, so this role goes beyond just writing code. You'll have significant input on architecture decisions, user experience, and product direction. As we scale, there will be opportunities to grow into a leadership or management position, mentoring junior developers and shaping our backend development strategy and onchain integrations.

This role is ideal for someone who is passionate about crypto and clean energy, values craftsmanship in their code, and thrives in dynamic startup environments where your work has a direct impact on the product's success and the company's mission.

This role is in-person in our New York City office.
