About the job
Build and automate test benches to characterize optical circuit switches, validate system models, and guide design decisions for Voyant Photonics’ OCS program.
What you'll do
- Run experiments and characterize optical performance of early chips and prototypes, including loss, crosstalk, polarization, wavelength dependence, and switching time.
- Compare measurements with device, circuit, and system models; explain discrepancies and report findings to guide design and specifications.
- Design, build, and automate scalable OCS test benches and analyze how performance changes as port counts grow.
What they ask for
- Hands-on experience with optical or photonic testing, characterization, or early-stage technology derisking; optical lab equipment, fiber handling and coupling, and standard electrical equipment.
- Experience automating test equipment and analyzing large datasets.
- Proficiency in Python for test automation and data analysis.
- BS in Electrical Engineering, Physics, Optics, or a related field; must be able to work on-site.
Nice to have
- Experience testing silicon photonic integrated circuits, optical switches, or datacom/telecom optical modules.
- Familiarity with photonic simulation tools such as Lumerical; wafer- or die-level probing, high-channel-count setups, or automated stages and fiber alignment systems.
