[Hiring] 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, ship decisions quickly, and 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.
