About LeydenJar
LeydenJar Technologies aims to become world’s innovation leader in advanced battery anodes to energize batteries for progress. High energy density of battery cells is an urgent and unmet need for a wide range of industries from consumer electronics to electric vehicles. By addressing the bottleneck of the battery anode, LeydenJar can improve this by 70% in an industry that can only improve 3% per year. Our pure silicon anode is regarded as the holy grail to achieve in the battery industry. Progress is not only about enabling new products, it also means a more sustainable supply chain, resilience and access to battery technology in geopolitical context and enabling electrification.
Our business model is to provide pure silicon anode rolls that fit directly in the battery plants of cell partners, allowing our clients to make step change in their product performance, or to allow new product categories such as e-flight. Our immediate focus in on the consumer electronics industry, with first automotive application development starting in shortly. To produce pure silicon anodes, we have crossed over from semicon thin film technology (plasma deposition) to anode production. This has given us a unique product quality that can last long without the problems associated with silicon as a battery material. To produce this material at scale we have pioneered roll to roll production tools that we will deploy in PlantOne in Eindhoven, expected to open in 2026. We will produce rolls and validate the production tools, allowing us to ramp up to large commercial production in PlantTwo (location to be determined). Ramping up to become a leading player in the battery market is an enormous opportunity, but also daunting development that requires a team of energy dense professional leaders
We are looking for a System Engineer PECVD that will be responsible for development, testing and validation of the PECVD subsystem. They work closely with the plasma scientist, process development and equipment development team to meet product targets, and ensure the seamless operation of critical R&D infrastructure. This role requires a strong understanding of hardware, software and processes related to PECVD.
Some of the key responsibilities are:
Development of a novel PECVD source in collaboration with the plasma scientist and process team, bringing hands-on PECVD engineering expertise into the development team;
Leading testing and validation of PECVD subsystem, providing feedback to the equipment development team
System and concept design of PECVD related sub-system of the equipment;
Working closely with the Plasma Scientist, translating stakeholder's wishes into design specifications and requirements, helping him managing sub-system interactions
Guiding PECVD related work of external engineering companies
Keeping all necessary documentation in place and up to date;
Supporting improvements and upgrades of existing equipment from the PECVD point of view.
Ensuring high quality of engineering and design work fit for PECVD process;
Reviewing and challenging system design in relation to PECVD competence.
Spreading your expertise amongst your colleagues.
Lead PECVD productivity improvement efforts.
Requirements:
Master or bachelor's degree in applied physics, mechanical engineering, process engineering or similar.
5+ years of working experience designing, testing and working with PECVD systems;
5+ years of experience in high-tech equipment and development;
