About LeydenJar

High energy density is an urgent, unmet need across consumer electronics, mobility, and the wider electrification of industry. Yet the battery industry typically improves by only 3% per year. LeydenJar addresses this by tackling the energy density bottleneck: the anode. Our 100% silicon anode, regarded as the holy grail of the battery industry, enables up to 50% increase in energy density.

We have demonstrated 500+ cycles without external pressure on multilayer pouch cells using our 100% silicon anode. We are now progressing into scaled-up production, with increasing customer traction, and our first anode factory PlantOne opening in 2026.

Taking our cell technology from the laboratory into repeatable, qualified manufacturing is the next step. This role of Product & Commercialization Manager, Drone cells is central to that effort.

What you can expect

As Product & Commercialization Manager, Drone cells at LeydenJar, your mission is to do everything necessary to make our venture into drone cell manufacturing a success. You will work closely with our R&D team and with our customers to define a cell product that’s commercially attractive and technically feasible. You’ll lead the certification and commercial roll-out of these cells. In many cases this will include close engagements with new and existing customers. You will also engage actively with the ecosystem. This ranges from advising our clients on battery pack integration options, sitting down with Ministry of Defense representatives to discuss our roadmaps and aligning with internal stakeholders (production, QC, logistics, etc.) to ensure delivery. Finally, you will also play a significant role in our efforts to insource cell manufacturing. This includes support in scoping the line and drafting RFQs down to hiring operators and overseeing first production. You will report to LeydenJar’s Chief Growth Officer.
