Software Engineer, Full Stack

Spark is building an advanced AI research tool that helps energy developers build solar farms and battery plants. As a Software Engineer at Spark, you'll be joining a small but ambitious team that has led Engineering and Product at Tesla, WeaveGrid, Brex, and Google.

The role involves designing and building core APIs, AI infrastructure, and data pipelines that scrape millions of data points weekly. You'll own features end-to-end, from ideation with founders to deployment and customer feedback. The position requires expertise in both frontend and backend development, using technologies like TypeScript, NextJS, NodeJS, and Postgres.

You'll be working on cutting-edge AI systems including agentic web browsing, RAG, and data extraction. The role requires close collaboration with founders to build the product roadmap and interact with customers to understand the energy industry's needs.

The ideal candidate has 3+ years of experience and values impact over perfection. You should be comfortable with startup-style rapid development, making pragmatic trade-offs between perfect and "good enough" code. The position requires someone who can work independently, tackle fuzzy goals, and effectively communicate solutions.

This is an excellent opportunity for someone interested in founding a company, as you'll gain firsthand experience in building a vertical AI company in the energy sector. The company is backed by top investors including AI Grant (Nat Friedman and Daniel Gross), founders of Brex, Plaid, and Helioscope.

The position is fully in-person at their San Francisco office, requiring 5 days per week presence. You'll be part of a team helping energy developers navigate regulations and accelerate the transition to renewable energy, with current customers including industry leaders like Colliers Engineering & Design, Standard Solar, and Cypress Creek Renewables.
