Role Overview

We’re hiring a Founding Engineer / Senior Full Stack Developer to help us build an advanced desktop application designed for secure, intelligent, and autonomous workflows. You’ll be one of the first engineering hires and play a critical role in owning the entire product engineering stack—from interface to system orchestration.

This is a high-ownership role for someone who thrives in early-stage environments, enjoys building performance-focused desktop systems, and wants to work at the cutting edge of AI-enabled automation.

What You’ll Work On

• Architect and build a high-performance Electron-based desktop application
• Develop intelligent frontend workflows using React 18, TailwindCSS, and TypeScript
• Build scalable backend services in Node.js 20 with support for secure tool orchestration
• 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
