• Prepare technical documentation including specifications, integration guides, and white papers tailored for the U.S. data center market.
• Ensure compliance with relevant U.S. industry standards and certifications (UL, IEEE, etc.).

Requirements

• Bachelor’s or Master’s degree in Electrical Engineering, Power Systems, or related technical field.
• 3+ years of experience as an application or field engineer in the data center or power infrastructure industry.
• Strong knowledge of power backup systems, UPS, batteries, and/or ultracapacitors.
• Familiarity with thermal management, grid-tied systems, and data center operational requirements.
• Excellent communication skills, both written and verbal.
• Ability to travel domestically (up to 25–40%) for customer meetings and site support.
• Authorization to work in the U.S.

Extra cookie points for additional qualifications:

• Experience working with Tier 1 or hyperscale data center operators.

• Knowledge of energy storage regulations and incentive programs in the U.S.

• Hands-on experience with simulation tools (e.g., MATLAB/Simulink, PLECS) or electrical CAD tools.

• Experience with industrial or grid-connected systems, especially in backup power applications.

Benefits

• We offer flexible working hours, with the possibility of mobile working without core working hours and sufficient freedom for your own ideas.

About Skeleton

Skeleton Technologies is a global leader in critical power infrastructure for AI data centers and electrical grid stability, founded in 2009. Power today is more than electricity.

It is national security, digital continuity, and economic resilience. Skeleton is the Backbone of Power: equipping AI data centers, electrical grids, defense systems, and critical infrastructure with the resilience to withstand surges, instability, and failure. Our power systems protect GPU clusters from millisecond-level spikes, enable hyperscalers to run at higher rack densities without grid compromise, and make AI data centers up to 40% more energy efficient. We keep the lights on when grids fluctuate, stabilizing electrical infrastructure under the combined pressure of accelerating renewable energy deployment and surging AI demand.

When power fails, critical operations stop. We exist to prevent that in microseconds. Powering the infrastructure that powers everything else.
