Sr. Silicon Photonics Design Engineer

Job Description Are you a passionate Silicon Photonics Design Engineer eager to contribute to groundbreaking research and development? Join our team and play a key role in designing and developing cutting-edge silicon photonics integrated circuits. You’ll lead the entire development process, from design and fabrication to testing and analysis, for complex photonic devices and systems-on-chip. Collaborate with experienced designers on innovative projects and large-scale silicon photonics circuits. Apply now and be part of a team pushing the boundaries of photonic technology!

How You Will Contribute And What You Will Learn

• Drive the architecture and development of next-generation optical engines in advanced Si photonics process technologies for high-performance pluggable optics and embedded solutions for coherent DWDM long-haul and metro transport applications.
• Own product definition, PIC architecture innovation, and specification of integrated photonic circuits for coherent Tx/Rx signal processing chains, critical optical components, and comprehensive test methodologies tailored to meet demanding requirements across long-haul, metro, and pluggable coherent optical systems.
• Spearhead link budget development and optimization across coherent optical transport links, driving analysis of system performance, channel impairments, chromatic dispersion, polarization effects, active and passive component margins, and foundry process capabilities to ensure first-pass silicon photonic designs meet aggressive performance targets in both long-haul and metro deployments.
• Champion design-for-test and design-for-manufacturing (DFM) best practices, establishing photonic device characterization strategies and test protocols to enable rapid volume ramp and high-yield manufacturing in next-generation coherent pluggable platforms and integrated transceiver solutions.
• Lead design reviews as a recognized subject matter expert in silicon photonic component design, setting technical direction and raising the bar for system-level performance, power efficiency, and manufacturability across diverse coherent optical applications.
• Drive cross-functional execution with photonics design, RFIC/EIC, DSP, packaging, product engineering, foundry technology partners, test development, and product leadership to architect and deploy scalable design automation, simulation frameworks, and test infrastructure that accelerates deployment of innovative coherent optic solutions.
