Intern Instrument Engineer Jobs in Princeton, NJ

Eulerity is an AI-native marketing automation platform. Not a legacy tool with AI bolted on. We serve enterprise brands including Mastercard, UPS Store, Uber Eats, and European Wax Center, automating digital advertising across thousands of franchise locations.
We are hiring a Product Management intern for the summer to work alongside our Head of Product.
Who we are looking for
This is not a shadow-the-team-and-take-notes internship. We are looking for someone who already builds. The kind of person who has shipped a side project, won a hackathon, written a Substack about something they care about, hacked together a tool to fix a problem in their own life, or otherwise gone from "I have an idea" to "this thing exists" without anyone telling them to. Who treats AI as the primary interface between ideas and execution. Who can hold their own in a technical conversation without needing to write production code.
If you have ever stayed up at 2am because you could not stop thinking about a product decision, you will feel at home here.
What you will actually do
You will work directly with our Head of Product and her team on real product work that ships. The shape of the role:

• Be in the room when product decisions get made, and contribute. We want your perspective, not just your attention.
• Use AI tools to move fast. Synthesize customer feedback, draft specs, prototype concepts, generate user stories, and accelerate research that would otherwise take days.
• Own a defined slice of product work end-to-end. Discovery, requirements, engineering handoff, and post-launch measurement.
• Run structured experiments. Define hypotheses, instrument analytics, read the results, and make recommendations.
• Conduct competitive analysis and market research, and bring us the so-what, not just the what.
• Translate messy technical discussions into clear requirements that engineers actually want to build from.

We hire interns when we have real work for them. You will not be running coffee or sitting silently in meetings.
What we want from you

• Current student or recent graduate, ideally in computer science, engineering, product design, math, or a similar technical field. We will weigh what you have shipped over your GPA.
• You have built something. A side project, a class capstone, an app, a tool, a website, a bot. Something you took from idea to existence. Be ready to talk about it in detail.
• Genuinely AI-native. You already build with AI tools, reason with them, and have your own opinions about which ones are good for what.
• Comfort reading code, querying data, and debugging. You do not need to write production code, but you should be able to follow what is happening.
• Sharp written and verbal communication. You can take a tangled problem and explain it cleanly in a few sentences.
• Strong product intuition. You can identify when something feels off before the data confirms it.

Logistics

• Summer 2026, with potential to extend based on performance.
• Hybrid out of our NYC Midtown office, 2 to 3 days per week in person.
• Minimum 20 hours per week, flexible schedule.
• $16 to $18 per hour.
• Lunch credits and unlimited snacks when in-office.
• AI tools budget. Use what makes you sharp.
• Direct mentorship from our Head of Product and senior team.
