Job Description

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.
  • 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.

We're not just about energy storage. We're about redefining energy for a net-zero future, and we'd love for you to be a part of our journey.
