Company

hirify.global provides rack-scale AI infrastructure through connectivity solutions based on CXL, Ethernet, NVLink, PCIe, UALink, and its COSMOS software suite.

What you will do

• Define and implement optical test architectures and flows for wafer probe, package-level characterization, and optical module validation.
• Execute characterization and qualification testing for co-packaged optics components and assemblies.
• Perform high-speed optical measurements including insertion loss, return loss, extinction ratio, eye diagrams, BER, and OMA.
• Design and build test stations using fiber alignment systems, optical switches, tunable lasers, optical spectrum analyzers, oscilloscopes, and BER testers.
• Develop automated test software, scripts, and frameworks for wafer-scale and production-level testing.
• Analyze large-scale test data, generate Cpk, GR&R, and SPC reports, support design reviews, and coordinate with engineering teams, suppliers, and foundries.

Requirements

• Master’s or Ph.D. in Electrical Engineering, Optical Engineering, Physics, Photonics, or a related field.
• 5–7+ years of experience in optical testing, photonic device characterization, or optical transceiver development.
• Strong knowledge of silicon photonics devices, including modulators, photodetectors, multiplexers, grating couplers, and edge couplers.
• Hands-on experience with OSA, OMA, tunable lasers, polarization controllers, power meters, high-speed oscilloscopes, BERTs, and pattern generators.
• Experience testing 100G/lane and higher optical links using PAM4 and NRZ, plus knowledge of IEEE 802.3, OIF-CEI, and CMIS standards.
• Programming experience in Python, MATLAB, LabVIEW, or C/C++ and familiarity with statistical analysis and data visualization.

Nice to have

• Experience with co-packaged optics or on-board optics architectures.
• Experience with wafer-level optical probing, automated photonics test platforms, and photonics test hardware and software.
• Experience transitioning test processes from laboratory or prototype environments to high-volume manufacturing.

Culture & Benefits

• Work within a broader test organization and collaborate across design, process engineering, supplier, and foundry teams.
• Contribute to an environment that values creativity, innovation, and diverse backgrounds and experiences.
• Potential eligibility for discretionary bonus, incentives, and benefits.
