2026 Financial Controller

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:

• →

  You have over 5 years experience in financial accounting, control or audit

• →

  You have an HBO, university or an accountancy certificate (RA is a big plus)
