Full Stack Engineer
Sol, San Mateo
The role
You'll build Sol's product surface end to end — from backend services and APIs to the modern, AI-native interfaces our customers use. The product is early and the surface area is wide: you'll regularly ship features that span data model to UI, working closely with the founding team and our domain architects.
What you will do
- Build product features across the stack: Kotlin/JVM backend services, APIs, and the frontend experiences they power
- Build dynamic, data-driven interfaces that adapt to each customer rather than static layouts
- Build conversational and agent-mediated experiences alongside traditional enterprise UI
- Contribute to the component and API patterns the product scales on
- Move fast with AI-assisted development as a first-class part of how we build
What you need
- You have deep backend experience in Kotlin or Java — services, APIs, and data models that hold up in production — and you design for composition, not one-off use
