Senior Software Engineer - iOS

People want to be informed and entertained. Great products make the two inseparable.

Noise is a platform to discover and trade trends. Every day, millions of people make predictions about what will continue to matter: a brand, a conflict, a new technology. These predictions shape the global economy and advance culture. AI slop and the internet have accelerated content production to such an extent that predicting trends has become nearly impossible.

Noise exists to solve this. We measure attention across the internet and allow people to trade on its future. The result is real-time markets on how brands, narratives, and ideas rise and fall. If we succeed, Noise becomes the standard for measuring attention and a new way to reveal what truly matters in the world.

A little bit about our team:

• Eight full-time employees based in NYC

• Fully in-person in SoHo, NYC

• Everyone either ships code, designs, or talks to users

• Build in the Unknown: We have no interest in iterating on what already exists. Our goal is to create a new type of consumer experience centered on invention, not optimization.

• Seek Truth Rapidly: We consider it a mistake to linger in speculation. We test, learn from feedback, and move forward with speed and clarity.

• No Passengers: Everyone at Noise — engineers, designers, marketers — is in the room, in New York City. We’re a small team moving fast with care and intensity. We solve hard problems together. You do not need permission to try new things.

• Action Your Taste: Our work carries the imprint of everyone who builds it.

We’re seeking a Senior Software Engineer with an iOS focus — someone who codes first and designs second. As the first in-house mobile engineer, you’ll own the iOS effort end-to-end: shaping the foundation, architecting the app, and driving it from zero to launch. You’ll work closely with the cofounders to ensure deep compatibility with existing web applications and to translate product vision into fast, reliable, and beautifully crafted mobile experiences. You care deeply about PREQ and product quality.

Responsibilities

• Prototype and iterate rapidly with the product designer to validate ideas.

• Architect and implement fast, reusable iOS components that scale across devices.

• Optimize for performance and accessibility, ensuring every frame and gesture feels native.

• Craft thoughtful motion and interaction systems — from transitions to micro-interactions.

• Shape and expand our design system, setting the standard for mobile craftsmanship.

• Collaborate across product, backend, and web teams to build cohesive end-to-end experiences.

Qualifications

• Deep experience in iOS development (Swift, iOS SDK) and the full lifecycle from concept to App Store launch.

• Strong command of performance, concurrency, memory management, and responsiveness.

• A refined eye for UI/UX details — motion, spacing, typography, and tactile feedback.

• Comfortable turning Figma or Adobe designs into production-ready code with precision.

• Bonus: experience in WebGL, Three.js, or creative coding for expressive, high-impact visuals.

Our Tech Stack

• Design: Figma, Adobe

• Frontend (web): React (Typescript), Vite, TailwindCSS

• Backend: Rust, Java, Typescript

• Research: Python, Pytorch

• Infrastructure: AWS, Cloudflare

• Smart Contracts: Solidity, Foundry, Slither

(Note: This is our broader stack — this role is focused on mobile iOS development.)
