- Manage subcon partners and drive NPI test development with a global OSAT team.
What you'll need
- Bachelor or Master of Science degree in Electrical Engineering or related field.
- 10 years of experience in sustaining high-speed RF products and Silicon Photonics that have moved into volume production.
- Experience with RF/Mixed-Signal/Silicon Photonics IC test with focus on yield, cost, and manufacturing process improvements.
- Experience with complex data analysis using JMP, Silicon Dash, PDF solutions, or other standardized semiconductor tools.
- Understanding of linear/limiting high-speed TIA’s, Drivers, Sipho and their test and characterization using RF test equipment in the lab.
- Hands-on wafer sort analysis experience for analog devices 67GHz, 110G, and larger.
- Solid understanding of DFm for SiGe semiconductor technologies.
Nice to have
- Familiarity with test bench equipment, including Network Analyzers, Sampling Oscilloscopes, Power Supplies, and Power Meters.
