This is not a "shadow a senior PM" internship. Sitting at the intersection of product, engineering, and customer discovery, you’ll own ideas end-to-end from week one.
The Building Radar Jeane team is building the AI layer that turns B2B construction sales from manual to proactive and intelligent - and you’ll actively decide what that looks like. You’ll leverage AI-assisted coding tools (Claude Code, Cursor, etc.) to rapidly build, test, and plug new features into our ecosystem to unlock real value loops. We don’t care about which tools you use and more that you pick the right ones to ship fast.
Activities
- Idea to Prototype: Translate hypotheses from customers, product, sales, and CS into working prototypes within days, not months - using AI-assisted coding as your superpower.
- Validate with Real Users: Run lightweight experiments with internal stakeholders and selected customers to test whether an idea actually creates value.
- Build for Real Usage: Take prototypes from "it works on my machine" to "sufficiently stable" so we can track real usage and learn from production data.
- Plug into Jeane: Connect your builds to the Jeane ecosystem (APIs, data, agents) so each experiment compounds into the larger product.
- Close the Loop: Instrument what you ship, surface insights, and feed learnings back into the Jeane roadmap.
- Be a Discovery Partner: Talk to customers and internal users, observe how they work, and turn observations into the next prototype.
Requirements
- Background: A technical/tech-affine background or degree is a plus (e.g., computer science, business informatics, or related). Whether you are in your Bachelor's, Master's - your skills and mentality matter most.
- Builder mindset: high energy, strong ownership, and a bias for shipping prototypes fast.
- Languages: Native or fluent German (C1/C2) is required, as you will interact directly with our German customers. Fluent English is our internal team language.
- Hands-on experience with AI-assisted coding for product prototypes (Claude Code, Cursor, v0, Lovable, or similar).
- Broad prototyping range across the stack (TypeScript/Python, basic frontend, APIs, light data work) - depth less important than speed and versatility.
- Strong product sense: you optimize for the user problem, not just the code.
- Comfortable with ambiguity and scoping fuzzy ideas into usable artifacts.
- Bonus Points (Tech): Exposure to AI agent frameworks, LLM tooling/evals, production instrumentation, or previous startup/side projects where you’ve already shipped working code.
- Bonus Points (Business): First experience in a customer- or stakeholder-facing role, helping you translate user feedback directly into product iterations.
Show us your work: Nothing shows us your builder mentality and skill better than your actual outputs. Production deploy, demo Loom or a slide deck - whatever you have to show what you did.
Links to what you built (GitHub/portfolio/demo video/live prototype) are highly appreciated.
