Android Developer Intern

Eulerity•New York, NY

3d•$16 - $18•Hybrid

About The Position

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 Android app is a critical surface for how clients interact with the platform — and we're looking for an intern who doesn't just write Kotlin, 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.

Requirements

Currently a student based in the NYC tri-state area
At least 1 year of Android development experience using Kotlin, Jetpack Compose, and Android Studio
Proficient in Kotlin (Java experience is a plus) with a solid understanding of the Android SDK and 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 Jetpack Compose / XML layouts and hands-on experience with Android libraries and APIs (Retrofit, Dagger/Hilt, Room, etc.)
Knowledge of Android design patterns and architectures (e.g., MVVM, MVI, Clean Architecture)
Experience with Git
You can take ownership of tasks and work independently, while also thriving in a collaborative team environment

Nice To Haves

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, a Play Store release — something you took from idea to existence
Hands-on experience with Agile development frameworks
Experience with unit testing and automated testing tools (e.g., JUnit, Espresso)
Comfort working with large volumes of data and thinking about performance at scale

Responsibilities

Take an active role in developing, testing, and maintaining our Android app using AI-first development practices — Agentic coding tools are your daily drivers
Implement new features end-to-end, from design through deployment, leveraging AI at every stage: architecture decisions, code generation, debugging, testing, and review
Write effective prompts and system instructions as a core engineering skill
Collaborate with engineers, UX designers, and product managers across all phases of the project lifecycle
Contribute to building smart, adaptive interfaces that leverage AI to personalize the user experience
