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.

Requirements

  • 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.

Benefits

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

What They Do

Skeleton Technologies specializes in high-power energy storage solutions, leveraging its proprietary curved graphene nanomaterial to produce supercapacitors and hybrid SuperBatteries. Their innovative products are designed for a variety of applications, including AI data centers, transportation sectors such as automotive and maritime, grid stabilization, and industrial uses. As Europe's largest ultracapacitor manufacturer, Skeleton Technologies maintains full control over its value chain, from raw materials to software and patents, ensuring superior performance and reliability in their offerings (source: wikipedia.org). Their product lineup includes the SkelCap SCA series cells, which are UL 810A certified for safety in automotive and UPS applications, and the SkelStart engine start modules, which boast an impressive 2,000 cold-cranking amps and a lifespan of over 1 million cycles.

Projects & Track Record

Skeleton Technologies has a strong track record of notable projects, including the opening of the Großröhrsdorf Superfactory in 2017, which significantly scaled their ISO-certified module production capabilities. They launched the SkelStart in 2015, recognized as the world's most powerful engine starter, and have developed space capacitors for the European Space Agency since 2011. In 2024, they are set to power the NTT IndyCar Series with their advanced supercapacitors, showcasing their commitment to innovation in high-performance applications (source: skeletontech.com). Currently, they are working on the €220 million Leipzig Superfactory, which is expected to produce 12 million cells annually and create 420 jobs, with production slated to begin in 2024-2025.
