Résumé du poste

CScale is building the interconnect for gigawatt-scale AI. We seek a hands-on Optical Component Validation Engineer to validate lasers, silicon photonic devices, and packaging interfaces in our optical engines.

You will define validation plans, build measurement setups (LIV, spectrum, coupling losses), analyze data, and work with photonics, packaging, and supplier teams to resolve root causes and improve yields. Strong lab skills and Python automation are essential.

Qualifications

• Experience with laser and photonic components testing.
• Lab experience with semiconductor lasers and photonic devices.
• Strong data analysis and statistics for optical data.
• Python or similar for automation of measurements.
• Clear communicator across engineering disciplines and with suppliers.
• Ability to work in ambiguous, dynamic environments.

Responsabilités

• Define validation plans for laser, silicon photonic, and packaging components.
• Build and run characterization setups: LIV, spectrum, coupling losses.
• Characterize devices at die/wafer level: loss, modulation, and detuning performance.
• Develop precision fiber-to-chip measurement methods and test structures.
• Correlate measurements with optical models to locate loss causes.
• Collaborate with photonics, packaging, and supplier teams.
