Principal Silicon Photonics Engineer

Job Title : Principal Silicon Photonics Engineer

Location : Austin, TX or San Francisco, CA (remote work will be considered in special cases)

Reports To : Chief Technology Officer (CTO)

About Neurophos : At Neurophos, listed as one of EE Times 2025 100 Most Promising Start-ups, we are revolutionizing AI computation with a groundbreaking photonic module that promises to redefine the world of AI. After three years of stealth R&D, we have engineered a technology platform delivering 100x performance gains in neural network computingpowering applications like Large Language Models (LLMs) and next-generation AI architectures. By integrating metamaterials with conventional optoelectronics, our compute-in-memory optical system surpasses existing solutions, paving the way for the future of AI hardware. We are scaling our elite engineering team to bring this transformative technology to market. Join us to shape the future of optical computing.

Position Overview : We are seeking a Principal Silicon Photonics Engineer to lead the architecture, design, and development of advanced silicon photonic devices for our AI acceleration platform. This role is ideal for a highly experienced and motivated engineer with a deep understanding of silicon photonics, including grating couplers, waveguides, semiconductor optical amplifiers (SOAs), and photodetectors, who are excited. The candidate will work closely with the CTO and cross-disciplinary teams to drive the design, validation, and commercialization of cutting-edge photonic modules. Initially, this position will be an individual contributor role with potential future opportunities to build and lead a team.

Key Responsibilities :

• Develop and maintain end-to-end system link budget.
• Architect, design, model, and optimize complex silicon photonic devices, including grating couplers, waveguides, SOAs, and photodetectors, for high-speed AI computing applications.
• Collaborate with external foundries to develop manufacturable designs using process design kits (PDKs) and ensure successful tape-out of silicon photonic components.
• Perform design-for-manufacturing (DFM) and design-for-test (DFT) evaluations to ensure scalability and robust production.
• Conduct and interpret optical simulations using industry-standard tools (e.g., Lumerical, Ansys, COMSOL, or equivalent).
• Work with optical fiber assemblies and ensure seamless integration with high-speed photonic systems.
• Perform experimental validation and characterization of silicon photonic devices in the lab.
• Collaborate closely with optomechanical, electrical, and software engineering teams to ensure system-level integration.
• Lead design reviews and contribute to the development of optical test plans, specifications, and manufacturing guidelines.
• Support the development of intellectual property (IP) and contribute to patent filings related to novel silicon photonic designs.
• Mentor junior engineers and contribute to the continuous improvement of silicon photonics design methodologies.
