## About 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. Build product features across the stack: Kotlin/JVM backend services, APIs, and the frontend experiences they power

## What they're looking for

- 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
- You understand your tools below the surface: JVM behavior, concurrency, data access patterns, where performance actually goes to die
- You're comfortable crossing into the frontend — working TypeScript familiarity and the willingness to ship UI, not just hand off an API
- You want breadth — features that run from data model to pixels — and the ambiguity that comes with shaping an early product
- You use AI coding tools daily and have developed real fluency with them — this is how we work, not an experiment
- You're scrappy, curious, and want the ownership that comes with an early team
