Photonic Design and Layout Engineer / Photonic Design and Layout Engineeress

Lightium AG - March 16, 2026

Join Our Team as a Photonics Design R&D Engineer

Are you passionate about pushing the boundaries of photonic integrated circuit (PIC) technology? Lightium, a leading-edge photonics startup, is seeking 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 crucial in advancing 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 in collaboration with our RF and optical simulation engineers.
  • Simulation: Supporting Lightium’s simulation activities by contributing to optical and RF simulations using state-of-the-art simulation environments.
  • PDK Development: Providing block-level functional models and statistical models involving fabrication and process tolerances to support Lightium’s PDK development.
  • Collaboration: Working closely with R&D teams across design, processing, fabrication, and optical testing to advance our PIC technologies.
  • Documentation and Reporting: Maintaining thorough documentation of design data, reporting findings, and implementing work instructions and scripts for mask generation.
  • Innovation: Staying 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: Initial work experience in photonic design at an industrial level. Prior experience with integrated photonics design, including TFLN, silicon photonics, SiN, InP, or related platforms is a plus.
  • Technical Skills: Strong proficiency in GDS mask generation, optical simulations, RF/antenna simulations, design-rule-check (DRC), and PDK development and improvement. Experience with optical proximity correction (OPC) is advantageous.
  • Organization & Documentation: Excellent organizational skills to manage multiple projects simultaneously, ensuring clean documentation of design data while following standard procedures and maintaining confidentiality.
  • Collaboration: Exceptional communication skills and the ability to work effectively within a multidisciplinary team.
  • Adaptability: The ability to thrive in a fast-paced startup environment, showing flexibility and resilience amid change.
  • Language Skills: Fluency in English is required. Knowledge of German or French is a plus.
