About the role
The Senior Manager, Photonics Quality Engineering leads product quality engineering for Semtech's InP photonics portfolio across gain chips, DFB laser chips, and high bandwidth photodetectors supporting coherent and IM-DD optical transceivers. The role owns product-level quality from device design through customer delivery, interfacing with fab operations, process engineering, and product teams.
What you'll do
- Own the product quality strategy across NPI, mass production, and end-of-life for InP photonics products supporting hyperscale and AI infrastructure customers. - Lead quality risk assessments, DFMEA reviews, and design qualification plans for new product launches, process transitions, and co-packaging or near-packaging optics platforms. - Drive diagnosis, root cause failure analysis, and 8D/CAPA closure for customer-escalated quality issues and field returns. - Report quality metrics through quality business reviews (QBRs), reliability qualification summaries, and customer corrective action updates. - Partner with InP wafer fabrication foundry and contract manufacturing partners to resolve process excursions and conduct supplier audits for new materials and processes.
What you'll need
- Bachelor's degree in Electrical/Electronic Engineering, Applied Physics, Materials Science, Optical Engineering, or a related field. - Knowledge of III-V compound semiconductor device physics, with emphasis on InP-based photonic devices including edge-emitting lasers, DFB/DBR lasers, gain chips, and semiconductor optical amplifiers (SOAs). - Working knowledge of InP epitaxial growth processes (MOCVD/MBE), material quality assessment, and defect management. - Knowledge of optical transceiver product engineering fundamentals, including LIV (Light-Current-Voltage), spectral performance, and optical power characterization test methodologies. - Experience identifying and analyzing device failure mechanisms such as facet damage, active region defects, grating defects, and contact degradation. - Written and verbal communication skills to interface across internal teams and directly with hyperscale customers.
Nice to have
- Master's degree in a related technical discipline. - Experience with high-speed optical transceivers, datacenter interconnects, or coherent optical communication systems within 400G/800G/1.6T/3.2T architectures. - Experience in semiconductor or photonics manufacturing quality engineering owning supplier quality management, customer quality interface, or reliability qualification programs. - Statistical data analysis experience using JMP, Minitab, or Python/R. - Exposure to Lean Manufacturing and Six Sigma methodologies, such as Green/Black Belt certification. - ISO 9001 and/or ISO 14001 Lead Auditor certification. - Familiarity with reliability standards for optical components, including Telcordia GR-468 and IEC standards. - Understanding of co-packaged optics (CPO) and near-packaged optics (NPO) architectures.
