Mobile iOS Developer Intern at Eulerity

<h3><strong>Why This Role Exists</strong></h3> <p>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.</p> <p>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.</p> <p>You'll be building features that real users depend on, not a sandbox project that lives in a repo no one checks.</p> <p>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.</p> <h3><strong>The Fast Facts</strong></h3> <ul> <li><strong>Compensation:</strong> $16-18/hour</li> <li><strong>Location:</strong> NYC Midtown — 3 days/week in office</li> <li><strong>Schedule:</strong> 30 hours/week</li> <li><strong>AI Tools:</strong> Unlimited. Claude Code, Copilot, whatever makes you sharp — we don't gatekeep tools here.</li> <li><strong>Start Date:</strong> As soon as possible</li> <li><strong>Perks:</strong> In-office lunches and unlimited snacks</li> </ul> <h3><strong>What You'll Actually Do</strong></h3> <p>This isn't a "shadow a senior dev and update button colors" internship. You'll own real work that ships to real users.</p> <ul> <li>Take an active role in developing, testing, and maintaining our iOS app using AI-first development practices — Agentic coding tools are your daily drivers</li> <li>Implement new features end-to-end, from design through deployment, leveraging AI at every stage: architecture decisions, code generation, debugging, testing, and review</li> <li>Write effective prompts and system instructions as a core engineering skill</li> <li>Collaborate with engineers, UX designers, and product managers across all phases of the project lifecycle</li> <li>Contribute to building smart, adaptive interfaces that leverage AI to personalize the user experience</li> </ul> <h3><strong>Who You Are</strong></h3> <p>We're looking for someone who's technically sharp, builds with AI by default, and is energized by shipping things that matter — not just completing tickets.</p> <p><strong>Non-Negotiables</strong></p> <ul> <li>Currently a student based in the New York City Tri-State Area</li> <li>At least 1 year of iOS development experience using SwiftUI, UIKit, and Xcode</li> <li>Proficient in Swift with a solid understanding of iOS frameworks</li> <li>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</li> <li>Strong prompting skills — you understand how to write effective prompts and system instructions to get high-quality output from LLMs</li> <li>Strong UI development skills in SwiftUI / UIKit and hands-on experience with iOS libraries and APIs (CocoaPods, SPM, Firebase, etc.)</li> <li>Knowledge of iOS design patterns and architectures (e.g., MVVM, MVC)</li> <li>Experience with Git</li> <li>You can take ownership of tasks and work independently, while also thriving in a collaborative team environment</li> </ul> <p><strong>Big Differentiators</strong></p> <ul> <li>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</li> <li>Experience building or fine-tuning prompts for code generation, debugging, or automated testing workflows</li> <li>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</li> <li>Hands-on experience with Agile development frameworks</li> <li>Experience with unit testing and automated testing tools</li> <li>Comfort working with large volumes of data and thinking about performance at scale</li> </ul> <h3><strong>What Makes Eulerity Different</strong></h3> <p>We are not a company that talks about AI. We are a company that runs on it.</p> <ul> <li>Our platform uses cross-learning AI agents that optimize across thousands of advertiser accounts simultaneously — not just one</li> <li>We have deep integration moats built over years with Google, Meta, Apple, and Microsoft — a barrier competitors can't replicate quickly</li> <li>We are lean, profitable, and intentional about every hire — even interns get real scope from week one</li> <li>Your work will ship. It will be seen by real users, measured in real results, and recognized on the team</li> </ul> <p>This is a place where interns build things that matter.</p>
