• Lead the definition, design, and integration of innovative DWDM line systems, open optical line systems (OOLS), ROADM architectures (CDC/Flex-Grid), controllers and coherent transponder platforms.
• Work closely with PLM, Eng, Architectureteam to Bridgetthe hyperscaler requirements to engineeringdeliverable and take accountability for the finaloutcome,
• Define technical vision, system specifications, and multi-year roadmaps for DWDM solutions that drive market leadership across Service Provider and Hyperscaler networks.
• Mentor and develop senior engineering talent, encouraging a culture of technical rigor, patent creation, and optical engineering excellence.

Minimum Qualifications

• Bachelors + 15+ years of related experience, or Masters + 12+ years of related experience, or PhD + 9+ years of related experience in Electrical Engineering, Optical Engineering, Physics, Telecommunications, or a related technical rigor.
• 15+ years of hands-on experience in Optical DWDM Systems: Extensive domain expertise in DWDM line system design, ROADM architectures (CDC, Flex-Grid, WSS), coherent optics, optical amplification (EDFA, Raman), and optical link budget/impairment modeling (OSNR, CD, PMD, nonlinearities).
• Experience crafting technical strategy, making critical architectural decisions, and developing product roadmaps for sophisticated optical transport platforms.
• Experience integrating hardware, embedded software, optical planning tools, and optical physical-layer control into carrier-grade and hyperscale production environments.

Preferred Qualifications

• Prior experience guiding engineering teams and interacting directly with Tier-1 Service Provider and Hyperscaler optical architects to tackle large-scale DWDM deployment challenges.
• Consistent track record leading end-to-end delivery of complex optical line systems, transponders/muxponders, or open optical platforms from concept to commercial deployment.
• Deep knowledge of modern optical network modeling, automated power/gain equalization algorithms, and optical performance monitoring.
• Active contributor to or recognized leadership in optical standards bodies and consortia (Open ROADM MSA, OIF, ITU-T SG15, or TIP Open Optical).
