About the Position

Kilby Labs is seeking a highly motivated and experienced Silicon Photonics Design Engineer to design silicon photonics solutions for advanced data communications applications and establish methodologies tools and automation flows for silicon photonics this role you will be responsible for the end-to-end design and layout of transmit and receive Photonic Integrated Circuits (PICs). You will play a critical role in helping to build up an internal design enablement toolset including PDK and verification flows. The role includes working closely with process development system architecture validation and product and test engineering team members to ensure successful prototyping product development and launch. The role requires a creative problem-solver who can develop unique breakthrough technologies that leap-frog the state-of-the-art and contribute across various aspects of a project depending on project needs.

Responsibilities may include but are not limited to:

• PIC Design - Design of passive and active PIC components such as advanced passive waveguide circuit elements and high speed active components such as modulators and Ge-based waveguide detectors.
• Layout and tape-out execution - Translating schematic level layouts to .gds files anddevelopment of PCells including both hands-on layout and working with remote layout engineering teams.
• Design Enablement and PDK development Assist with Building and maintaining a Process Design Kit and schematic-driven layout automation including development of design rules and design rule checking.
• Layout Verification Development of DRC and LVS checks for layout verification to ensure first-pass silicon success
• Design for manufacturability Collaborate with design systems architecture and packaging teams to ensure designs meet specifications with high yield. Link design rules to process capabilities and test yield data.
• Design for test Ensure designs include advanced DFT features including strategies and architectures enabling wafer-level and die-level volume testing.
• Develop and implement volume-product-ready solutions that are power- and cost-efficient contributing to the development of the launch of datacom transceiver products.
• Ensure component models and design rules correlate to volume test data by closing the loop between manufacturing test data and design simulations using tools such as JMP.
• Develop PICs based on both external fixed and custom Si fabrication processes working closely with process teams.
• See designs through to mass production by collaborating with product engineering and operations teams.
• Participate in R&D to develop next generation photonics technologies drive IP development.
• Present work and findings to internal and external stakeholders.
