Key skills for this role
Eulerity is an AI-native marketing automation platform — not a legacy tool with AI bolted on. We serve enterprise brands like Mastercard, UPS Store, Uber Eats, and European Wax Center, automating digital advertising across thousands of franchise locations. We've crossed $10M ARR, largely bootstrapped, and we're accelerating.
Our iOS app is a critical surface for how clients interact with the platform — and we're looking for an intern who doesn't just write Swift, but builds with AI as their primary development tool. At Eulerity, AI-first development isn't a buzzword — it's how we actually ship code. Our engineers use Claude Code, agentic coding workflows, and prompt engineering as core parts of their daily process. We expect you to do the same.
You'll be building features that real users depend on, not a sandbox project that lives in a repo no one checks.
If you've shipped an app, already use AI coding tools to move faster than your peers, and know the difference between a good prompt and a great system — read on.
Compensation: $16-18/hour
Location: NYC Midtown — 3 days/week in office
Schedule: 30 hours/week
AI Tools: Unlimited. Claude Code, Copilot, whatever makes you sharp — we don't gatekeep tools here.
Start Date: As soon as possible
Perks: In-office lunches and unlimited snacks
This isn't a "shadow a senior dev and update button colors" internship. You'll own real work that ships to real users.
Take an active role in developing, testing, and maintaining our iOS app using AI-first development practices — Agentic coding tools are your daily drivers

Currently a student based in the New York City Tri-State Area
At least 1 year of iOS development experience using SwiftUI, UIKit, and Xcode
Proficient in Swift with a solid understanding of iOS frameworks
You already build with AI — Claude Code, Copilot, or similar agentic coding tools are part of how you work, not something you've tried once
Strong prompting skills — you understand how to write effective prompts and system instructions to get high-quality output from LLMs
Strong UI development skills in SwiftUI / UIKit and hands-on experience with iOS libraries and APIs (CocoaPods, SPM, Firebase, etc.)
Knowledge of iOS design patterns and architectures (e.g., MVVM, MVC)
Experience with Git
You can take ownership of tasks and work independently, while also thriving in a collaborative team environment
You're genuinely AI-native — you've restructured your entire development workflow around AI tools because it makes you dramatically faster, not because it's trendy
Experience building or fine-tuning prompts for code generation, debugging, or automated testing workflows
You've shipped something real outside of coursework: a side project, a hackathon app, an App Store release — something you took from idea to existence
Hands-on experience with Agile development frameworks
Experience with unit testing and automated testing tools
Comfort working with large volumes of data and thinking about performance at scale
We are not a company that talks about AI. We are a company that runs on it.
Our platform uses cross-learning AI agents that optimize across thousands of advertiser accounts simultaneously — not just one
We have deep integration moats built over years with Google, Meta, Apple, and Microsoft — a barrier competitors can't replicate quickly
We are lean, profitable, and intentional about every hire — even interns get real scope from week one
Your work will ship. It will be seen by real users, measured in real results, and recognized on the team
This is a place where interns build things that matter.
