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.
first-of-a-kind energy technology is designed, integrated, and ultimately deployed at scale.

functioning product.
thinking with a strong execution mindset, focusing on practical engineering solutions that accelerate the path to commercial
fusion energy.
Systems Architecture defines which machines Proxima builds, and why. The department owns the architecture of the Alpha
stellarator: the set of systems that make up the machine, how the whole is dimensioned, and the top-level requirements that flow
down to every subsystem. It also leads plasma engineering for Alpha and Stellaris — coil and plasma shape optimization — sitting
at the bridge between science and technology, physics and engineering.
Help translate ambition into systems that last.
You will work directly with the Chief Scientist as the operational and strategic backbone of Systems Architecture. You interface
across all Sys. Arch. teams and contribute to external-facing work: board reporting, strategy offsites, stakeholder engagement.
Your instinct is to build systems that outlast your involvement, creating durable processes rather than personal dependencies, and
leaving things in better shape than you found them. Your technical background gives you the judgment to operate credibly in a
deeply technical environment and to design internal infrastructure that's coherent, low-friction, and built to last.
When cross-cutting initiatives arise, special projects that need a clear owner and draw on expertise from multiple teams you're
the person who picks them up and sees them through.

You'll help build the company that keeps European industry competitive for the long-term. 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.
