You apply once - this application covers all our internship positions across departments 2. Tell us your preferences - rank the areas you're most interested in (we ask in the application form) 3. First call - we'll come prepared with a clear proposal on which team we think fits best and why. We discuss your skills, our needs, and where you can have the most impact 4. Case study - if we move forward, you'll work on a case with the team lead from your proposed department 5. We match and place you - you join a specific team & are all set to have an impact from day 1 Once you're in, you'll work primarily in your department. Depending on interest and capacity, there are usually opportunities to contribute to cross-functional projects as well to broaden your horizon. We also host regular events with top-tier founders and speakers from the startup ecosystem - e.g. Andreas Klinger at Lunch & Learn, 2-day AI Hackathon in our office, Basti Schuon at Lunch & Learn - so you get exposure to the full picture of building a startup, not just your corner of it. WHAT YOU NEED TO WORK AT TACTO * Experience in a fast-paced environment (startup, scale-up, consulting, whatever pushed you) * Self-driven - you don't need hand-holding * Naturally curious - you ask questions and dig deeper * You actually want to build things and take ownership * Strong communication skills in German and English * You care about the problem we are solving & are mission-aligned - helping the European Industry to stay competitive in the long-term WHERE OUR PREVIOUS INTERNS WORK NOW After Tacto, over 10 former interns have founded their own companies, with e.g. 3 already going through Y Combinator. Others have joined programs like CDTM (5+ acceptances), moved into top consulting firms, or joined early-stage startups and VCs. The common thread: they all got a real understanding of what it takes to build and scale a company. OUR BACKGROUND Tacto is building the intelligence layer that connects AI to the physical world of manufacturing, starting with procurement. AI is transforming every industry, but it stops at the factory gate. The knowledge that holds manufacturing together - part costs, suppliers, materials - is scattered across systems and people. Over 50% of a product's cost originates from suppliers, making procurement the single largest cost lever in manufacturing and the missing connection between the digital and the physical world. Yet it still runs on Excel and legacy systems. We're changing that with our Procurement Intelligence Platform, trusted by hundreds of companies running billions of Euros of material. Based in Munich, we are 100+ passionate builders who are in-office, with high expectations, fast growth, and a lot of fun. We are supported by >€50m from Sequoia, Index, and Europe's leading tech entrepreneurs and industry veterans. WHY IT MATTERS Manufacturing forms Europe's economic backbone, driving a fourth of Europe's GDP and providing over 30% of jobs. These hidden champions and global market leaders manufacture the physical world around us, from the machines that build our cities to the medical devices that save lives. But the world is changing. The US dominates the digital world of bits. China is scaling the world of atoms, manufacturing at unprecedented speed and scale. Geopolitics are more uncertain than ever. Europe's strength lies in its deep industrial knowledge through generations of engineering. Manufacturing worldwide runs on European machines and software. But that heritage is only an advantage if we leverage it in the age of AI. Tacto builds the AI that connects Atoms and Bits, empowering our Industrial Base to Stay Stronger and building a lighthouse for European tech. WHAT WE OFFER The people at Tacto are passionate about building the organization, growing themselves, and our product while having fun and being real. We have high expectations, great talent density, and a culture where your ambition, performance, and agency are what count - not where you come from or how big your ego is. You'll grow at the forefront of AI, have real ownership and impact, and be surrounded by the best people in their field who challenge you and make you better every day. That is demanding and rewarding, but that's where we thrive. Besides that you have: * Money: Competitive salary & equity in the company with real upside, so you are invested in our success * Workplace: A vibrant in-office culture (> 4 days/week) in a beautiful office in central Munich * Development: A development budget and regular exposure to exceptional people, e.g., Lunch & Learns, peer mentoring, external speakers * Time off: 26 + 4 vacation days per year (4 fixed “company rest days”) as well as regular off-sites and team events * Health: Wellpass membership, of course, a fruit basket (!), and access to Jobrad, for your health * Family & Social Security: Voluntary pension contribution, voluntary KITA subsidy for your children Tacto is an equal opportunity employer. We are committed to equal employment opportunity regardless of race, religion, sexual orientation, age, marital status, disability, or gender identity. Please do not submit personal data revealing racial or ethnic origin, political opinions, religious or philosophical beliefs, trade union membership, data concerning your health, or data concerning your sexual orientation.

Proxima Fusion

WHO WE ARE Proxima Fusion is Europe’s fastest-growing fusion company and the continent’s best-funded fusion player, as well as the first spin-out from the Max Planck Institute for Plasma Physics (IPP). Backed by over €650M and powered by a growing team across Munich, Zurich, and Oxford, we are developing the hardware and infrastructure needed to deliver the world’s first commercial stellarator fusion power plant. Our concept advances the most mature fusion technology out there, the Wendelstein 7-X stellarator, through two next-generation machines: Alpha and Stellaris. Our work combines stellarator optimization, advanced computation, machine learning, and high-temperature superconducting magnets to unlock higher-performance designs that were previously out of reach. Turning these designs into a functioning fusion power plant requires excellence and ownership across every discipline, from physics and engineering to software, manufacturing, law, and business functions.
