- Develop and optimize system architectures for integrating Skeleton's ultracapacitors into AI data center UPS, backup power, and energy efficiency applications.
- Conduct on-site visits, technical trainings, and product demonstrations.
- Support system design, including electrical schematics, thermal considerations, and lifecycle cost analysis.
- Work closely with R&D and Product Development to communicate field feedback and improve product-market fit.
- Prepare technical documentation including specifications, integration guides, and white papers tailored for the AI data center market.
- Ensure compliance with relevant industry standards and certifications.
- Bachelor's or Master's degree in Electrical Engineering, Power Systems, or a related technical field.
