Your Team, Your Impact

Your team develops silicon photonics-based optical engines and components at the heart of next-generation AI and data center infrastructure, directly shaping how AI systems connect and scale. You will work at the intersection of silicon photonics, advanced packaging, and high-speed electronics. Join a group of curious, highly motivated engineers embedded in a culture that is flexible, open, highly international, and genuinely people-centered. Zurich consistently ranks among the world’s top cities for quality of life and is one of Europe’s leading technology hubs, seamlessly combining innovation with exceptional living standards.

What You Can Expect

• Define, simulate, the architecture of high-frequency electrical interfaces for next-generation optical engines (400G/lane CPO and beyond)
• Perform co-design across photonics, analog/ASIC design, and packaging teams to optimize performance, power efficiency, and signal integrity
• Perform testing, characterization, and qualification of components and integrated systems
• Develop and validate end-to-end link budgets, correlating simulation and measurement across electrical and optical domains
• Analyze and interpret measurement data to identify performance limitations and drive design improvements
• Perform root cause analysis of complex signal integrity issues across electrical and optical domains

What We're Looking For

Qualifications

• Currently enrolled in a Master’s or PhD program in Electrical Engineering, Photonics, Physics, or a related field, with an expected graduation date after the internship
• Solid foundation in RF/microwave engineering, transmission lines, and signal integrity fundamentals (S-parameters, impedance matching, loss and crosstalk mechanisms)
• Coursework or research exposure to optical communications, silicon photonics, or electro-optical devices (modulators, photodetectors, lasers)
• Experience in one or more of the following (research or coursework counts):
  • EM or circuit simulation (HFSS, CST, or ADS), or RF PCB design
  • High-frequency or electro-optical measurements (VNA, oscilloscope, AWG, BERT), ideally in a university lab or prior internship
  • Python or MATLAB for data analysis, instrument automation, or system/link simulation
  • High-speed link concepts: PAM4 signaling, equalization (FFE, DFE, CTLE), and metrics such as BER, SNR, and eye diagrams
• Exposure to advanced packaging (2.5D/3D integration, co-packaged optics)

Personal qualities

• Curiosity and initiative, with the ability to work independently on a well-scoped project
• Collaborative, willing to learn from and work with cross-functional teams
• Clear communication, written and verbal, including presenting results to technical audiences
• Comfortable with ambiguity and eager to learn in a fast-paced environment

Interview Integrity 

To support fair and authentic hiring practices, candidates are not permitted to use AI tools (such as transcription apps, real-time answer generators like ChatGPT or Copilot, or automated note-taking bots) during interviews.

These tools must not be used to record, assist with, or enhance responses in any way. Our interviews are designed to evaluate your individual experience, thought process, and communication skills in real time. Use of AI tools without prior instruction from the interviewer will result in disqualification from the hiring process.

This position may require access to technology and/or software subject to U.S. export control laws and regulations, including the Export Administration Regulations (EAR). As such, applicants must be eligible to access export-controlled information as defined under applicable law. Marvell may be required to obtain export licensing approval from the U.S. Department of Commerce and/or the U.S. Department of State. Except for U.S. citizens, lawful permanent residents, or protected individuals as defined by 8 U.S.C. 1324b(a)(3), all applicants may be subject to an export license review process prior to employment.
