# Full Stack Engineer

- **Company:** SOL LLC
- **Location:** San Mateo, CA, United States
- **Contract:** Permanent contract
- **Skills:** Java (Programming Language), Application Programming Interfaces (APIs), Artificial Intelligence, Data Security, Java Virtual Machine (JVM), TypeScript, Backend, Kotlin, Front End Software Development
- **Published:** June 17, 2026
- **Apply:** https://www.indeed.com/viewjob?jk=5c114a3a77d64d10

## About the Role

Do you have experience in UI implementation?, * 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

## Description

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.
