Join a groundbreaking project focused on designing and building next-generation spectrographs for detecting Earth-like exoplanets. You will be part of a world-leading research environment, working at the intersection of astrophysics, optical design, and astronomical instrumentation. This fully funded PhD position at ETH Zurich offers the chance to contribute directly to high-impact international missions and the future of exoplanet science.

• Advance the optical design of the HARVY spectrograph, based on an existing concept study.
• Evaluate, characterise, and optimise key novel optical components.
• Lead the design and manufacturing of key subsystems during the instrument construction phase.
• Contribute to preparing and carrying out the on-sky test campaign planned for 2028.
• Work closely with experts in astrophysics, optical design, and instrumentation.
• Participate in scientific writing, proposal preparation, and international collaboration.

• Master's degree in physics, astrophysics, optics, or a closely related field.
• Strong interest in astronomical instrumentation and exoplanet science.
• Experience or strong interest in optical design, spectroscopy, or precision measurements.
• Programming and data analysis skills (e.g. Python, MATLAB, Zemax, or similar tools).
• Ability to work both independently and as part of an international research team.
• Fluency in English, both spoken and written.

• Fully funded PhD position with a competitive salary according to ETH Zurich standards.
• Work in an interdisciplinary and international research environment.
• Develop expertise in EPRV instrumentation, optical design, system-level performance modelling, and more.
• Engage in laboratory validation, integration, and on-sky commissioning of astronomical instruments.
• Enjoy ETH Zurich's commitment to diversity, inclusion, and sustainability.
• Benefit from Swiss employment conditions and social benefits.
