100x (YC S22) Is Hiring a Founding Front End Engineer
by shardullavekar | 2025-12-30 01:00:03+00:00
Location: Bangalore, India (Koramangala)
Compensation: Competitive Salary + Significant Equity (YC Standard)
Founders: Shardul Lavekar (ex-Airtel AI, ex-Ola) & Parth Mudgal (ex-Flipkart, ex-Ola)

At 100x.bot, we are building the interface for this future. We are not just another "AI Wrapper." We are a deep-tech company backed by Y Combinator, Accel, and Inventus, solving the hardest problem in automation: making browser agents reliable, fast, and accessible to everyone.

Most AI agents today are slow, expensive, and hallucinate frequently because they "think too hard" about every click. We take a different approach: "Record once, Automate forever." We combine the deterministic speed of record-and-replay technology with the semantic intelligence of LLMs to create agents that utilize self-healing DOM maps to navigate the chaotic web with human-like resilience.

The Opportunity: More Than Just UI
We are looking for a Frontend Craftsperson to join our core engineering team in Bangalore.

This is not a role for someone who just wants to center divs or convert Figma files into React components. We are looking for an engineer who can architect the client-side experience for autonomous agents. You will be building the "cockpit" from which users control their digital workforce.

What You Will Architect
The Agent Visualization Engine: You will build complex, interactive graph-based interfaces that visualize agent workflows. Users need to see the logic flow—loops, conditionals, and "self-healing" events—in real-time.

Dynamic MCP Interfaces: You will build systems that dynamically generate UIs based on Model Context Protocol schemas. If an MCP server exposes a new tool, your UI should instantly adapt to support it, without a code deploy.

High-Performance Streaming UI: Our agents generate massive logs (DOM snapshots, network events, execution traces). You will use virtualization (e.g., react-window) and atomic state management (Zustand/Jotai) to render these streams at 60fps, ensuring the UI never lags behind the bot.

The "Recorder" Experience: You will refine our Chrome Extension overlay, ensuring it injects cleanly into any third-party website (using Shadow DOM encapsulation) to capture user intent without breaking the host page.

The Tech Stack
We run a modern, type-safe stack designed for velocity and reliability.

Frontend: React, TypeScript, Next.js

Styling: Tailwind CSS (with Shadow DOM handling)

State: Zustand / TanStack Query (for high-frequency updates)

Protocol: Model Context Protocol (MCP), WebSockets, Chrome Extension APIs

Who You Are
A React Expert (2+ Years): You understand the React reconciliation algorithm inside out. You know why useEffect is dangerous for high-frequency data and how to use useRef or useSyncExternalStore to optimize performance.

TypeScript Native: You don't just use any. You write robust, generic types that mirror complex backend schemas. You are comfortable sharing types between the extension background script and the UI.

A "Craftsperson": You care about micro-interactions. You understand that trust is built through UI feedback—a loading spinner, a hover state, a smooth transition. You take pride in building developer tools that feel like magic.

Systems Thinker: You can reason about asynchronous systems. You understand race conditions, websocket reconnections, and the complexity of communicating between a Content Script, a Background Worker, and a React UI.

High Agency: In a small YC team, nobody will hand you a ticket. You will identify problems, design solutions, and ship them.

Why Join 100x.bot?
Work on the Bleeding Edge. You will be a pioneer in the space of AI Agents.

YC Culture: We move fast. We ship daily. We value product instincts over bureaucracy. You will have significant ownership and equity.

Complex Engineering: You won't be bored. You are building a browser automation engine, a recording studio, and an IDE—all in the browser.

Work directly with Shardul and Parth to shape the product roadmap.

How to Apply
Email me your GitHub and a link to a complex UI you have built.

Note: We value actual build history over resumes/degress.
Show us something that proves you are a craftsperson.
