Software Engineer

The engineering team at First Street is the backbone of our mission: using technology and data to help the world understand and adapt to climate risk. We’re an AI-native team building the systems that power our global products—tools relied on by customers to make informed, climate-aware decisions.

As a Fullstack Software Engineer, you’ll be a product-facing engineer responsible for delivering end-to-end features across frontend and backend systems. You’ll work closely with product managers, designers, and data partners to translate complex climate data into performant, accessible, and intuitive user experiences.

This role is ideal for an engineer with strong frontend fundamentals who is comfortable working across the stack and collaborating deeply with cross-functional partners.
