Zurich consistently ranks among the world’s top cities for quality of living for expatriates and is Europe’s leading tech hub, a city that seamlessly blends multicultural innovation with stunning natural surroundings.

As an intern, you will work on real projects with mentoring from experienced engineers. You will see how photonic devices go from concept to design, layout, and tape-out.

What You Can Expect

Depending on your interests and the team's needs, you will:

• Support the development of test and characterization methods for photonic components, products, and subsystems.
• Help design and validate test setups and measurement solutions for R&D and production applications.
• Perform hands-on laboratory measurements, including optical and high-speed electrical characterisation.
• Analyze measurement data and troubleshoot unexpected results to support product development.
• Develop measurement software, automation scripts, and data analysis tools to make testing faster and more reliable.
• Work with design and other multidisciplinary teams to define measurement requirements and test strategies.
• Document your work and present your results to the team.

What We're Looking For

• Currently enrolled in a Master's in Electrical Engineering, Photonics, Physics, Electronics, Mechatronics or a related field, with an expected graduation date after the end of the internship.
• Foundation in photonics, optics, electronics, or semiconductor physics.
• Interest in silicon photonics, optical communications, and experimental work.
• Some hands-on lab experience through coursework, a thesis, or projects (for example, optical or electrical measurements, or working with test equipment).
• Solid programming or scripting skills for data analysis or instrument control (Python preferred).

Nice to have (any of the following):

• Experience with lab instrument automation (e.g., VISA/SCPI).
• Familiarity with high-speed or RF measurements, such as signal generators and oscilloscopes.
• Experience with optical test equipment such as lasers, optical spectrum analyzers, or probe stations.

You Also Bring:

• Curiosity and initiative, with the ability to work independently on a well-scoped project.
• Openness to feedback and eagerness to pick up new tools and topics quickly.
• Clear written and verbal communication, including presenting your results to the team.
• A collaborative attitude and willingness to learn from and work with colleagues across teams.
