Join to apply for the Photonics Layout Engineer role at Lightium
Are you passionate about pushing the boundaries of photonic integrated circuit (PIC) technology? Lightium, a leading-edge photonics startup, is looking for a skilled Photonics Design R&D Engineer to drive the development of new layout and design methodologies for our innovative thin‑film lithium niobate (TFLN) platform. This role offers a unique opportunity to contribute to the next generation of photonics solutions while collaborating with top academic institutions.
Position Summary
As a Photonics Layout Engineer, you will define, implement, and execute wafer‑level and block‑level designs and floor‑planning of our internal and customer designs on our TFLN‑based PIC platform. Your contributions will be pivotal in advancing design innovation using state‑of‑the‑art software, bringing our photonic technologies from concept to mass production.
Key Responsibilities
Photonic Design: Develop and optimize various photonics PDK components—including passive, electro‑optical, and active components based on TFLN—using FEM or FDTD simulation methods in Lumerical or COMSOL.
PDK Development: Develop, implement, and maintain the PDK across EDA design software such as Nazca, Luceda, and Synopsys. The PDK encompasses both layout and physical models of each component.
PIC Circuit Layout: Model and simulate PIC designs (including GDS layouts) at the circuit level, focusing on innovative solutions to improve performance and reliability.
Collaboration: Work with the fabrication team to ensure designs are manufacturable and meet quality standards, and implement the PDK physical models based on statistical measurements.
Customer Guidance: Provide technical support and expertise to sales and marketing teams, assisting in customer engagement and product specification.
Technical Expertise: Stay up‑to‑date with industry trends and advancements in PIC technology and design methodologies.
Documentation: Document and maintain comprehensive records of PDK revisions, updates, and usage guidelines.
EU Projects: Participate in and contribute to international, national, and publicly funded projects such as Horizon Europe, including grant writing and reporting.
What Our Ideal Candidate Brings
Technical: GDS mask generation, floor‑planning, and block‑level design of cutting‑edge photonic components for internal and external stakeholders.
Design: Translating block‑level specifications into photonic designs in collaboration with RF and optical simulation engineers.
Simulation: Supporting Lightium’s simulation activities by contributing to optical and RF simulations using state‑of‑the‑art environments.
PDK Development: Supporting PDK development by providing block‑level functional models and statistical models accounting for fabrication and process tolerances.
Collaboration: Working closely with R&D teams across design, processing, fabrication, optical testing, and characterization to advance PIC technologies.
Documentation and Reporting: Maintaining thorough documentation of design data and reporting findings, as well as implementing work instructions and scripts for mask generation.
Innovation: Staying current with the latest photonics advancements, incorporating new metrology techniques and technologies into the R&D landscape.
