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 Photonic Design and Layout Engineer, you will define, implement and execute the wafer-level and block-level designs and floor-planning of our internal and customer designs in our TFLN-based PIC platform. Your contributions will be pivotal in continuing the innovation at the design level using state-of-the-art software packages, bringing our cutting-edge photonic technologies from concept to mass production.

Responsibilities

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 together with our RF and optical simulation engineers.

Simulation: Supporting Lightium’s simulation activities by contributing to optical and RF simulations using state-of-the-arts simulation environments.

PDK Development: Supporting Lightium’s PDK development by providing block-level functional models and statistical models involving fabrication and process tolerances.

Collaboration: Work closely with the R&D teams from design, processing, fabrication to optical testing and characterization, contributing to cross-functional projects to advance our PIC technologies.

Documentation and Reporting: Maintain thorough documentation of design data and report findings, as well as implement work instructions and scripts for mask generation.

Innovation: Stay up-to-date on the latest advancements in photonics, incorporating new metrology techniques and technologies into our R&D landscape.

What Our Ideal Candidate Brings

Educational Background: A degree (MSc or PhD) in Photonics, Physics, Electrical Engineering, Communications, Material Sciences or a related field.

Experience: First work experience in photonic design at an industrial level. Prior experience with integrated photonics design, such as TFLN, silicon photonics, SiN, InP or related photonics platforms are a plus.

Technical Skills: Strong proficiency in GDS mask generation, optical simulations, RF / antenna simulations, design-rule-check (DRC), PDK development and improvement. Prior experience with optical proximity correction (OPC) is a plus.

Organization & Documentation: Strong organizational skills to plan your work schedule between multiple projects, clean documentation of design data, following standard working procedures, and use best practices to maintain confidentiality.

Collaboration: Excellent communication skills and the ability to work effectively in a multidisciplinary team.

Adaptability: The ability to thrive in a fast-paced startup environment, demonstrating flexibility and resilience in the face of change.

Language Skills: Fluency in English is required. Knowledge of German or French is an advantage.
