Senior Photonic Design Engineer at Lucidean

As a Senior Photonics Design Engineer at Lucidean, you will lead the design, simulation, and optimization of high-performance passive and active photonic components for next-generation datacom transceivers. In this role, you will work across the organization to own the PIC lifecycle end-to-end—from DOE-driven device design and layout through packaging, PCB integration, and system-level modeling using both simulated and measured data. You will define test methodologies and work closely with the team to execute validation and reliability studies, and drive yield and failure analysis to deliver robust, production-ready photonic solutions.

• Design, simulate, and optimize passive and active photonic components using a variety of simulation tools like RSoft, Lumerical, HFSS, EMPro, COMSOL, Sentaurus, and Silvaco.
• Plan and execute Design of Experiments (DOEs) to optimize photonic components.
• Design layouts for high-speed optical transmitters and receivers on tools such as GDS Factory, Luceda IPKISS, and Opto Compiler.
• Perform system-level simulations, integrating both simulated and real test data, using tools such as Opt Sim and VPI.
• Oversee assembly, packaging, and integration of PICs with electronic components on PCBs.
• Define and implement standardized test plans for photonic components and PICs.
• Conduct comprehensive testing and validation of high-speed PICs and optoelectronic assemblies, including transmitters and receivers.
• Define and execute reliability studies and failure analysis for photonic components, PICs and optoelectronic assemblies.

• M.S. or Ph.D. in Electrical Engineering, Physics, or related field.
• Experience with design, test, and integration of photonic components for telecom or datacom transceivers, including lasers, MZMs, photodiodes, and passive components
• Experience delivering photonic components and PICs for telecom or datacom products.
• Hands‑on experience developing and executing test plans for PICs.
• Experience with PIC product packaging, testing, and qualification.
• Proficiency in the simulation and design tools listed under Key Responsibilities.
• Strong teamwork, collaboration, and communication skills.

• High-speed modulator and detector design and test experience.
• Yield, reliability and failure analysis experience.

• Push the frontier of optical interconnect technologies for AI computing in exciting start-up.
• Work alongside a dedicated, diverse team focused on making a tangible impact.
• Contribute to and help shape a flexible and dynamic startup environment with a culture of continuous learning and development.
• Competitive salary, equity options, and a comprehensive benefits package.
