[Hiring] Staff Kotlin Desktop Engineer @WhyHireWrong?

Role Description

You will build a desktop application in Kotlin and Compose Desktop that deploys, configures, and manages AI models on local hardware, including NVIDIA Spark and DGX Spark. This is not a web app with a desktop wrapper. It is a native desktop control plane that handles:

• Model lifecycle
• Agent configuration
• System load visualization
• LLM proxy routing

You will create the UI for:

• Model management dashboards
• Agent configuration screens

You will integrate with backend REST APIs to handle model deployment and implement configurations using:

• TOML
• JSON
• YAML

You will build LLM proxy routing to connect coding agents like Claude Code and Codex to locally hosted models. You will package the application into native installers for:

• Windows (MSI)
• Linux (DEB)
• macOS (DMG)

The team is small. You will own features end to end, and your decisions will ship quickly. You will work on problems that do not have Stack Overflow answers, navigate OS-specific quirks, and design solutions that have not been built this way before.
