Material Scientist

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.

As a Material Scientist in Product Development Department, you play a key role in designing, synthesizing, characterizing and optimizing pure silicon anodes, and you take end-to-end ownership of the development topics that turn our technology into products. You own your topics from hypothesis to validated result: you design and run the experimental work, characterize the material, conduct the in-depth analysis, and drive the technical decision that follows. You work with a high degree of autonomy: you are trusted to run complex development topics independently and to set their technical direction, in close coordination with the Product Technical Lead.

Your work sits at the heart of our technology: learning and establishing the relationship between PECVD process conditions, material properties and battery performance, planning and executing experiments to improve anode performance, and building the characterization methods that define the Si anode product. You do this in close coordination with the battery, process, equipment engineering and production teams, and with external partners, research institutes and universities.
