Cell assembly process engineer (m/w/x)

Job Description

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 more 40% energy efficient. We keep the lights on when grids fluctuate, stabilising 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.
