About the role
•
We are seeking a highly motivated Photonics Validation Engineer to join our team. In this role, you will be responsible for validating photonics sub-systems and packaged opto-electronic modules — building test infrastructure from the ground up and driving failure analysis from component level through module level. This position requires hands-on expertise in optical and electro-optic testing, strong troubleshooting instincts, and the ability to work closely with a multidisciplinary engineering team. Experience with EIC control, firmware/FPGA/ASIC-based test environments, coherent communications, and data analysis is essential. Background in free space optics, micro-optics, packaging, and III-V semiconductor physics is a plus. You will work alongside a world-class, cross-functional team in a fast-paced and rapidly growing environment.
What you’ll do
•
Build test benches and automated test setups from scratch for photonics systems, components, and packaged opto-electronic devices
•
Design, execute, and refine test plans and validation methodologies across wafer, chip, eval board, and sub-module levels
•
Perform spectrum analysis, noise analysis and FFT-based signal analysis
•
Validate coherent communication systems and modules (e.g., coherent receivers, DSP-linked subsystems)
•
Perform failure analysis efforts — root-causing device and system failures across optical, electrical, and firmware layers, and driving corrective actions
•
Perform passive optical testing (insertion loss, return loss, wavelength response, etc.)
•
Troubleshoot and debug test setups and design issues, identifying and resolving challenges
•
Analyze and visualize test data to characterize device performance and identify trends or deviations
•
Interface with EIC controls, firmware, and embedded software during test bring-up
•
Collaborate with FPGA/ASIC teams to support test automation, debug, and validation workflows
•
Work closely with cross-functional teams (design, packaging, manufacturing, product) to drive issues from detection to resolution
•
Document test procedures, results, and failure analyses; communicate findings clearly to internal stakeholders
•
Support the transition of test methodologies from R&D into high-volume manufacturing
Required Qualifications
•
Bachelor’s degree in Electrical Engineering, Photonics, Applied Physics, or a related field; a Master’s or Ph.D. is welcome but not required
•
3–7 years of relevant industry or applied research experience in photonics validation, optical testing, or opto-electronic systems
•
Hands-on experience testing photonic or opto-electronic components, subsystems, or packaged modules
