Material Scientist LeydenJar Eindhoven, Netherlands Posted on Sep 18, 2026 Material Scientist - pure silicon anode Do you want to contribute to a more sustainable world? Are you excited to help shape the future of battery technology and consequently the future of consumer electronics and mobility? Can you not wait to dive into a VC-backed deep tech scale-up with the ambition to change the world? We are currently looking for an energetic Material Scientist - pure silicon anode to join our innovative and ambitious organization. About LeydenJar At LeydenJar Technologies , we're on a mission to redefine the future of energy storage. Our goal is to become the world's innovation leader in advanced battery anodes, empowering the next generation of batteries that drive progress. Why does this matter? Because the world needs higher energy density batteries not just for better consumer electronics, but for electric vehicles, e-flight, and beyond. While the battery industry typically advances by only 3% per year, our breakthrough pure silicon anode technology delivers an improvement of up to 70%, a true game changer. Often called the "holy grail" of the battery industry, our technology unlocks new possibilities for electrification, sustainability, and resilience in global supply chains. What we do: · We produce pure silicon anode rolls that fit seamlessly into existing battery cell manufacturing lines, enabling customers to make a quantum leap in performance or create entirely new product categories. · Our initial focus is on consumer electronics, with automotive applications already in development. · By leveraging semiconductor thin-film technology (plasma deposition) and scaling it to battery anodes, we've overcome the long-standing challenges of silicon in batteries, delivering durability and efficiency at scale. To meet global demand, we're scaling up: · PlantOne in Eindhoven opened in 2026 and is now ramping up to produce an...
