Senior Software Engineer

Station A

Station A is the world's first AI-powered clean energy marketplace.

OtherRemoteTeam 11-50H1B No Sponsor

Station A is a technology company reimagining how clean energy is bought and sold. Our distributed team is made up of climate-minded technologists, strategists, and operators committed to making climate action a no-brainer for everyone. We combine proprietary software with industry expertise to guide commercial real estate owners and operators through their decarbonization journey, starting with evaluation of their portfolios and culminating in transactions through our clean energy marketplace. About the Role: We’re looking for a Senior Software Engineer who can own meaningful slices of the product end-to-end, ship quickly without cutting corners, and help raise the technical bar as the team scales. For example: - Own discrete product areas end-to-end (e.g. a portfolio evaluation workflow, a scoring model, or a transaction flow), including clarifying requirements with Product, tech-speccing the solution, implementing backend & frontend changes, shipping, and supporting it in production. - Be the owner for specific systems or services, including ongoing improvements, bug fixes, performance tuning, and technical debt in that area. - Translate product goals into shipped code, including breaking down problems into scoped tickets, making pragmatic tradeoffs, and delivering incremental value week over week. You’ll work across one of our core pods: - Evaluation: geospatial analytics, data pipelines, site qualification, modeling - Transaction: marketplace workflows, RFPs/RFQs, provider matching, deal execution This is a hands-on role for someone who enjoys building real systems under ambiguity, collaborating tightly with Product and Design, and leaving codebases better than they found them. Responsibilities: - Own and ship end-to-end product work: from problem framing → design → implementation → rollout - Build and maintain scalable backend systems and APIs (primarily Python + SQL) - Contribute to frontend product surfaces (TypeScript / React) where needed - Design pragmatic data models and workflows that support real customer use cases - Improve system quality through testing, observability, and thoughtful refactors - Collaborate closely with Product, Design, and other engineers to balance speed, scope, and correctness - Help define “what good looks like” through code reviews, pairing, and example-setting - Participate in technical discussions around architecture, tradeoffs, and platform evolution
