Job Description
Miraex is looking for an enthusiastic Photonics Test Engineer to join us on our mission to bring quantum computers to the necessary scale for real-life, practical applications. To enable this, we are building integrated circuits that bridge the gap between the world of microwave photons and optical photons. On the job you will:
Help us create industry-defining quantum hardware products by developing and executing testing and characterization strategies for our products
Design, build, and operate optical and electro-optical measurement setups for the characterization of integrated photonic devices
Perform high-quality experimental measurements, including optical transmission, loss, modulation response, and device performance under varying conditions
Develop and maintain automated data acquisition and control systems for efficient and reproducible testing
Analyze and interpret experimental data, including benchmarking against expected performance and identifying discrepancies with models or simulations
Collaborate closely with fabrication, design, and RF teams to provide feedback from measurements and help iterate on device performance
Contribute to the development of cryogenically compatible testing setups and measurement techniques, where applicable
Maintain awareness of the latest measurement techniques and testing methodologies used in advanced photonic and quantum devices
Document experimental procedures, results, and insights clearly, and communicate findings effectively to the broader team
Proactively identify opportunities to improve test infrastructure, measurement accuracy, and data reliability
Your Qualifications
Required:
Ph.D. in electrical engineering, applied physics, photonics, or a closely related field (or Master’s degree with 2–5 years of relevant industry experience)
Hands‑on experience in the experimental characterization and testing of integrated photonic devices, such as waveguides, interferometers, resonators, or modulators
Strong understanding of electromagnetic wave propagation and light–matter interaction, including familiarity with the Pockels effect or related electro‑optic phenomena
Proven experience setting up and operating optical measurement systems, including fiber alignment and coupling, laser sources and detectors, polarization control and calibration.
Experience with automated data acquisition and experimental control, using Python or similar tools (e.g., instrument control via VISA, SCPI, or equivalent)
Proficiency in scientific programming and data analysis, including processing large datasets, visualization, and extraction of key device parameters
Ability to analyze and interpret experimental results, including identifying discrepancies between expected (simulated or theoretical) and measured performance
Experience troubleshooting complex experimental setups, including identifying sources of noise, loss, or instability in optical systems
Strong communication skills, with the ability to clearly present experimental results and insights to cross‑functional teams (design, fabrication, RF, systems)
Experience working in multidisciplinary environments, collaborating across photonics, electronics, and fabrication teams
Familiarity with RF or high‑speed measurement techniques (e.g., S‑parameters, bandwidth characterization) is a strong plus
Cleanroom experience in lithography, deposition, etching, characterization, and metrology for production of photonic devices
Experience with foundries specialised in thin film lithium niobate, silicon nitride, or silicon photonics on a variety of substrates
Experience simulating mixed optical and RF or superconducting systems
Experience scripting for experimental control and data analysis down to cryogenic conditions
Demonstrated ability to contribute to our IP portfolio
If you don’t think you fit all the criteria, but you have what it takes to make an impact as an engineer at Miraex, we’d still love to have a chat so we can see if you might be a great fit.
Our offer
Participation in an international team with industrial and academic partners.
Contribution to challenging industrial R&D as well as scientific projects.
Exciting possibilities to put your knowledge into practice and make an impact.
Being part of a fast‑growing, investor‑backed deep‑tech startup
Highly attractive working environment, in the heart of the Lake Geneva region, Switzerland
Participation to our Employee Stock Option Plan
All the possibilities offered to people working at the EPFL Innovation Park (networking, access to experts, lots of social and sport activities)
We are an Equal Opportunity Employer and do not discriminate against any employee or applicant for employment because of race, colour, sex, age, national origin, religion, sexual orientation, gender identity, status as a veteran, and basis of disability or any other protected class.
