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 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.

• Hands-on experience with commissioning or ramp-up of a new production line or plant.
• Experience in battery, semiconductor, automotive, electronics or similar automated production is preferred.
• PLC programming and troubleshooting (e.g. Siemens TIA Portal, Rockwell Studio 5000).
• Experience with HMI/SCADA, servo drives, robotics, vision systems and industrial networks (PROFINET, EtherNet/IP).
• CMMS setup and use (e.g. SAP PM, Maximo).
• Knowledge of reliability methods: RCA, FMEA, preventive and predictive maintenance, OEE.
• Machine safety and safety PLCs, with knowledge of NFPA 70E, NFPA 79 and Cal/OSHA.
• Fluent English and the ability to work with international equipment suppliers.
• A hands-on problem solver who stays calm during breakdowns.
• Structured and documentation-minded.
