  • Integrate with external systems like CLI tools, terminal processes, file systems, and MCP-like interfaces
  • Build efficient local storage, memory, and prompt-pipeline management systems
  • Work on token and session lifecycle, agent command execution, and sandboxed operations
  • Ship cross-platform (Windows & macOS) builds using Electron and Vite pipelines

Tech Stack

You should already be comfortable with most of the following:

  • Frontend: React 18, Tailwind CSS, TypeScript, Vite
  • Backend: Node.js 20, Express.js, CLI process spawning, OS-level scripting
  • Desktop: Electron 25, IPC communication, Electron Forge/Builder, native packaging
  • AI/Agent Integration: REST APIs to LLMs (Claude, GPT, etc.), prompt engineering, token/tokenizer management
  • System-Level: File system manipulation, workspace persistence, multi-threaded job handling
  • Tool Control & Integration: Interfacing with command-line tools (MCP-like integrations), automated I/O
  • Other: GitHub Actions, secure storage, error logging, telemetry pipelines

What We’re Looking For

  • 4+ years of full stack development experience with real-world Electron app delivery
  • Strong proficiency in JavaScript/TypeScript (ES6+), including bundling and module systems
  • Production-level experience with React and managing state in large apps
  • Deep understanding of backend architecture, async task management, and secure file handling
  • Ability to work independently in a fast-paced early-stage environment
  • Comfortable with cross-platform builds (Windows & macOS)
  • Bonus: Experience with embedded AI assistants, autonomous agent frameworks, or toolchain orchestration

What We Offer

  • Competitive salary: ₹17–20 LPA
  • 0.4% equity via ESOP pool (with early joining incentives)
  • High autonomy and strategic influence—work as a true co-creator
  • Remote-friendly and async collaboration culture
  • Opportunity to build a developer-first product from scratch with real AI depth
