Eulerity is a rapidly growing technology company revolutionizing marketing automation for small businesses and franchises with our industry-leading proprietary software. We were founded by leaders from Google, Facebook and Yahoo! with more than 20 years of digital advertising, engineering and marketing experience.

Your Role:

• Take an active role in developing, testing, and maintaining our backend services — leveraging AI agents to accelerate and improve your work
• Implementing new features, starting from design to deployment
• Help come up with new features and product ideas, using AI tooling to prototype and iterate quickly
• Collaborate with other teams on features and releases
• Assist with the preparation of documentation, training, and support of various systems

About You:

• You have at least 1 year of hands-on experience working with AI agents (e.g. Claude, Copilot, Cursor, or similar coding agents) to build, debug, and improve software
• Experience with LLMs, AI agent frameworks, or AI-assisted product development (you've actually used these, not just read about them)
• At least 1 year of experience building backend solutions with Java
• You have a strong willingness to continuously learn, experiment with, and deepen your knowledge of AI tools and how they can be applied to real engineering challenges
• You understand how to use agents and LLMs to find the right resources, generate and review code, and solve problems more effectively
• You enjoy coming up with creative solutions to complex problems
• Comfortable working with third-party APIs
• Able to work in conjunction with other team members

Requirements:

• Currently a student graduating in Dec 2026 or later
• Based in the NYC tri-state area
• Able to commit minimum 30 hours per week

Benefits:

• Pay $17-$19/hour
• Mentorship with regular peer review sessions
• Free lunch and unlimited snacks
• Full GitHub Copilot access with frontier LLMs and coding agents from Anthropic, Google, and OpenAI — keeping you equipped with the best AI tooling available

Internship Details:

• The internship will run from May until August with potential to extend based on candidate performance + availability
• Hybrid work flexibility provided with in-office expectations at least twice per week

Why This Role Exists

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.

The Fast Facts

• 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

What You'll Actually Do

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 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

Who You Are

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.

Non-Negotiables

• 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

Big Differentiators

• 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

What Makes Eulerity Different

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.
