Role brief

Overview

We're building an AI-powered tool designed to revolutionize iOS & MacOS development, aiming to provide developers with a smart, efficient, and automated coding experience. Similar to how Cursor AI enhances code writing and debugging, we're developing a Cursor for iOS Development tailored specifically for Xcode, Apple's flagship IDE. Currently, Xcode lacks AI capabilities, but our product seeks to fill that gap by automating tasks and assisting with code generation, editing, and debugging.

Our long-term goal is to fully automate iOS development, making it more efficient for the millions of developers working within the Apple ecosystem. Ultimately, we envision our tool as the "Devin for iOS development", an essential platform for iOS developers that integrates seamlessly with Xcode.

We're growing rapidly, with more than 5000 users joining the past 2 months. We're funded by Khosla Ventures, Kleiner Perkins, SV Angel, Chapter One, and Ravikant Capital. Our users include teams from Duolingo, Huawei, eBay, Robinhood, LinkedIn, Zillow, FanDuel, Citizen, ElevanLabs, ByteDance, Notion, and The Economist.

The Role

We need experienced engineers to help build our Xcode integration. You'll be one of the first engineers on the team.

What You'll Do

- Build systems to analyze and generate iOS code

- Create reliable backend services for our AI tools

- Develop and maintain our Xcode plugin

- Write infrastructure to handle code processing at scale

- Make architectural decisions that will shape our codebase

What We're Looking For

- Strong foundation in algorithms and data structures

- Experience building backend systems or developer tools

- Background in low-level systems or infrastructure at major tech companies

- CS, Math, or Physics degree with strong academic record

Nice to Have

- Direct experience with Xcode or iOS development

- Knowledge of Apple's development ecosystem

- Background in code analysis tools

- Experience with large-scale AI systems

The Details

This is a full-time role. You'll work directly with the founding team to build core features. We're looking for people who can tackle complex technical problems and write reliable code.

Location: San Francisco, in-person hybrid.
