Senior Hardware Engineer (m/f/x)

Skeleton's Engineering Department is looking for a driven and experienced

Hardware Engineer (m/f/x).

Your responsibility areas:

• Define electronics functionality and translate system-level requirements into detailed hardware specifications (100+ devices per year).
• Ensure compliance with industry standards, cost targets, and customer expectations throughout the development cycle.
• Conduct risk, reliability, and redundancy analyses (e.g., FMEA, FTA).
• Develop electronics concepts, select components, and design schematics, PCB layouts, wiring, and interfaces to meet functional, EMC/EMI, environmental, and manufacturability requirements.
• Perform electrical simulations and testing to verify system behaviour and support DFM/DFT activities with manufacturing partners.
• Prepare and maintain documentation, including design logs, reports, manuals, and production files.
• Support hardware quality through validation testing, specification writing, and close cooperation with test engineers.
• Define and validate end-of-line (EoL) testing, including equipment, fixtures, and software requirements; analyse yield data and failure modes to drive improvements.
• Collaborate closely with manufacturing and quality teams to resolve design or process issues and support troubleshooting when needed.
• Work cross-functionally with internal product, engineering, and production teams, guiding product build as needed.

• At least 5 years of experience in electronics design for small-series or larger production.
• Hands-on experience transitioning designs into manufacturing, including DFM/DFT, industrialization, and test setup.
• Practical know-how in EoL testing, yield and failure analysis, and continuous improvement during production ramp-up.
• Experience working in multidisciplinary teams (hardware, software, mechanics, testing, production).
• Strong skills in schematic design, PCB layout, component selection, simulation, prototyping, and testing.
• Proficiency in Altium Designer or a comparable ECAD tool; experience with LTspice, Matlab, or similar simulation software.
• Ability to prepare documentation and reports; basic data analysis skills in Excel or similar tools.
• Bachelor’s or Master’s degree in electronics, mechatronics, electrical engineering, or embedded systems.
• Good verbal and written English.
• Proactive, detail-oriented, analytical, and eager to learn and improve.

• We offer flexible working hours, with the possibility of mobile working without core working hours and sufficient freedom for your own ideas.
• A flat hierarchy culture - fostering our great working atmosphere.
• A motivating opportunity for continuous growth at Skeleton.
• An additional day off every year for your birthday.

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.
