iOS Developer

CometChat Overview

CometChat is a full-stack conversational platform built to unify every layer of interaction - bringing together real-time conversations (chat, messaging, voice, and video), AI Agents, moderation, notifications, and analytics in one modular, developer-first solution.

We were also recognized on Forbes' 2026 America's Top 500 Startup Employers List - a reflection of the team and culture we've been deliberate about building.

We believe the interface of the future is conversation - not clicks. Every app will soon have an AI layer that's as native as text messaging today. That's why we're building the infrastructure for the world's AI-powered conversations - from human-to-human, to human-to-agent, to multi-party collaboration with AI in the mix.

From AI onboarding assistants that get users productive in minutes, to copilots that perform complex workflows in-app, to intelligent moderators that protect and guide communities in real time - our AI Agent platform makes it all possible.

With CometChat's ready-to-use UI kits, powerful SDKs, and our Full Stack AI Agent Platform, product teams across startups and enterprises can launch safe, scalable, and smart in-app interactions faster than ever.

Why Join Us Now

We're at the tipping point where AI becomes a native part of every conversation. At CometChat, you'll help shape a future where users can talk to their apps as naturally as to a friend - where agents think, reason, act, and collaborate with humans in real time.

You won't just be joining a product team - you'll be building the standard for AI interaction layers: agent-aware UI, intelligent guardrails, rich actions libraries, and multi-party collaboration between people and AI.

If you want to help define how the next billion users will communicate - and push the boundaries of what's possible in real-time, AI-powered engagement - we'd love to work with you.

What we mean by AI-native

AI-native here means you build with agents by default. We expect 100% of the code to be generated via agentic tools (Cursor, Claude Code, and similar), while you own everything that actually matters: problem framing, architecture, tradeoffs, review quality, tests, performance, and security. This is not "vibe coding." The code is generated. The thinking is yours. You should be great at steering agents, validating output, catching subtle issues early, and debugging code you did not manually write.

Why AI-native

Software development is changing permanently, and we are leaning all the way in. You will work in a team that ships fast with agents, where your leverage comes from judgment and systems thinking rather than typing speed. You will get access to whatever AI tools you need (Cursor, Claude Code, or anything else that makes you effective), and the freedom to use them aggressively. If you want to operate at the edge of how modern engineering gets done and level up your output, this role is built for that.

Join us to build where AI meets human connection.
