Maintenance & Equipment Electrical Engineer

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 will be involved in the Plant One start-up phase, where the new plant utilities will be made operational and the new machines will be assembled and commissioned. You will be added to the equipment group, responsible for the new plant and equipment installation.

• The existing machines will be fully in production and are a very good learning experience of the processes and maintenance requirements.
  You will work with the production group, doing several continuous improvement projects.

• You will be responsible for the electrical installation according dutch regulations (like NEN3140, Scope 8)

• Ensure optimal performance of vacuum deposition equipment through preventive and corrective maintenance.

• Lead continuous improvement initiatives to increase uptime, reliability, and process performance.

• Maintain and improve technical documentation, procedures, and safety systems.

• Build and manage a critical spare parts strategy and an efficient safety stock to support uninterrupted equipment operation.

• Close cooperation with co-workers on maintenance and improvement plans.

• Manage maintenance-related contracts and vendors.

• Responsible for plant-wide utility system performance, including HVAC, compressed air, and process gases.

• Drive compliance with safety, environmental, and quality standards.

• Provide technical input and operational support to future factory construction and engineering projects, ensuring equipment and infrastructure design aligns with long-term maintenance and performance requirements.
