Description
About Daylight
Daylight is the decentralised 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 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.
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 optimise their energy usage while participating in our decentralised 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.

- Design and implement Solidity smart contracts that underpin Daylight's decentralised energy markets
- Develop Daylight's decentralised data storage and validation layer using modern frameworks (e.g. Commonware, Snapchain L3)
- Architect secure oracle flows to feed real-world energy data onchain
- Contribute to architecture planning and drive technical design decisions that ensure scalability and security
- Optimise the application stack for maximum speed and reliability
- Embrace CI/CD methodologies and infrastructure-as-code practices to streamline deployments
What we're looking for
- 5+ years of experience developing APIs and backend services
- 2+ years of experience writing Solidity smart contracts
- Strong understanding of API Development and best practices
- Experience with Python, Django, PostgreSQL and Redis
- Proficiency in writing clean, readable, and well-documented code
- Experience with REST APIs, GraphQL, and network request handling
- Familiarity with version control systems, particularly Git
- Knowledge of backend performance profiling and optimisation techniques
- Experience with testing and managing AWS infrastructure and Kubernetes
- Familiarity with crypto and related infrastructure, specifically EVM
- Ability to work in a fast-paced environment with changing requirements
- Strong problem-solving skills and attention to detail
- Familiarity with DeFi protocols, especially stablecoins, lending markets, liquid staking, or yield optimisation systems
- Experience integrating offchain data via oracles
What we offer
- Competitive salary and equity package
- Opportunity to shape a category-defining product from the ground up
