Staefa, Switzerland

Internship in Charging Solutions Verification (m/f/d)

If you are looking for an opportunity to dive into hardware and software testing and get hands-on experience in real-world verification challenges, this opportunity is for you.

As an intern, you will co-develop a testing platform designed to validate both software and hardware specifications at a system level, covering functional behavior, power management, and electro-mechanical testing.

Your focus will be on building and maintaining test infrastructure for charging solutions, developing automated test scripts, and running experiments to assess charging behavior in realistic hearing instrument usage scenarios. You will turn raw measurement data into clear reports and actionable insights.

Your work will span the full testing lifecycle, and you will be part of a cross-functional engineering team, giving you direct exposure to real day-to-day challenges in electronics, firmware, and system-level performance — all within the context of innovative hearing device technology.

More about the role

• Establish, calibrate, maintain test infrastructure for charging solutions verification
• Develop, maintain, and execute automated test scripts/frameworks to execute verification plans
• Develop test cases for new developed functionalities and adapt existing test cases to new product variations
• Run experiments to assess charging behavior and safety mechanisms in realistic hearing instrument usage scenarios
• Collaborate with engineering teams on requirements and test strategies
• Collect, analyze, and visualize measurement data, prepare clear reports and documentation of test procedures and results.
• Support and troubleshoot measurement setups and contribute to continuous improvement of test workflows.
• Collaborate with engineers on electronics, firmware, integration with the hearing devices, and system-level performance investigations.

More about you

• BSc or MSc in Electrical Engineering or related field
• Basic programming knowledge (Python, MATLAB, C)
• Knowhow in manual and automated hardware testing and troubleshooting of electronic devices is a plus
• Hands-on mindset, curious, with strong analytical skills and attention to detail.
• Comfortable with data logging/analysis and willing to contribute to test setup, execution, and reporting.
• Strong logical thinking and problem-solving skills
• Good communication and teamwork skills
