Full job description

Summary

Munich (in-office) · Full-time · 3-6 months · Start ASAP

We're looking for someone who can join us as soon as possible for a 3 to 6-month internship. Availability to work from our Munich office alongside the team is essential, as the close, hands-on collaboration is a big part of what makes this role work.

Your mission

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.
  • 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.

Your profile

  • 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.

Why us?

  • Real ownership from week one: Your name is on what you ship. You own the experiment, ship the prototype, talk to the customer - no ticket queues, no "wait till Q3".
  • Access to what you need to succeed: Top-tier AI coding stack out of the gate – Claude Code, Cursor, frontier LLMs, our internal SDKs, and the data and APIs to plug into. If a tool helps you ship faster, we'll get it. (We don’t care if you prefer Cursor or Claude Code — we look for people who are smart enough to leverage the best AI tools available to get the job done.)
  • Direct line to real customers: Sit in on calls with sales, CS, and our German-speaking customers. Your prototypes meet real users - not internal demos.
  • Mentorship from builders, not managers: Pair directly with colleagues from product and engineering and the founders. Async by default, hands-on when you need it - your Buddy makes sure you're never stuck.
  • Shape the revolution: We're rewriting B2B sales for a $12T industry in the GenAI era. Few internships let you touch a product Bosch and Holcim actually use.
  • Worldwide vibes: A highly motivated team from 11+ nations shipping daily.
  • In-office culture with flexibility: We love the maker energy in our Munich office, where we collaborate closely daily. However, if you need a deep-work day from home now and then, that’s absolutely fine.
  • Sport is our passion: In-house gym plus EGYM Wellpass (we cover 50%+). Ship hard, recover harder.
  • Cool events: Mountain weekends, Oktoberfest, off-sites, go-kart racing - we celebrate what we ship.

About us

Building Radar develops the "System of Action" for sales in the construction industry – a leading AI platform that helps sales teams systematically identify relevant business opportunities, successfully win them, and manage them sustainably.
The construction industry is a $12 trillion market. However, despite established CRM systems, sales processes are often still implemented manually, fragmented, and inefficiently, which leads to lost revenue and a lack of scalability.

Our vision is to become the leading and central operating system for B2B sales in the construction industry in the age of GenAI. Instead of individual isolated tools, we are building an integrated end-to-end platform on which our customers can actively plan, manage, and implement their go-to-market strategy.

Building Radar is on a clear growth path. Together with customers such as Bosch and Holcim, we have already helped generate an order value of over $2.5 billion. In addition to economic success, we attach great importance to our corporate culture: we are creating a dynamic, international team culture in which top talents enjoy working, taking on responsibility, and growing together. This is also reflected in our 100% recommendation rate – for five years, we have also been among the top 5% of employers on Kununu.
