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 computing—powering 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.

Qualifications:

  • PhD in Photonics, Physics, Electrical Engineering, or a related discipline.
  • Minimum of 10 years of industry experience in silicon photonics design, development, and productization.
  • Demonstrated expertise in designing and optimizing photonic integrated circuits, including grating couplers, waveguides, SOAs, and photodetectors.
  • Proven track record of taking silicon photonic devices from concept through to commercial production using leading foundries.
  • Hands-on experience working with PDKs, performing DFM/DFT, and managing tape-outs.
  • Experience characterizing and validating silicon photonic devices in a laboratory environment.
  • Familiarity with optical fiber coupling and high-speed photonics applications.
  • Strong problem-solving skills and the ability to work both independently and collaboratively in a dynamic environment.
  • Excellent communication skills, with the ability to clearly convey complex technical information to diverse stakeholders.

Preferred Skills:

  • Industry experience in optical communications, quantum computing, optical computing, or augmented reality (AR).
  • Knowledge of advanced photonic integration techniques and emerging photonics technologies.
  • Experience with high-speed photonics and signal integrity in integrated systems.
  • Proficiency in scripting or programming (e.g., Python, MATLAB) for design automation and analysis.
  • Demonstrated leadership experience or the potential to build and manage a technical team.

What We Offer:

  • A pivotal role in an innovative startup redefining the future of AI hardware.
  • A collaborative and intellectually stimulating work environment.
  • Competitive compensation, including salary and equity options.
  • Opportunities for career growth and future team leadership.
  • Access to cutting-edge technology and state-of-the-art facilities.

How to Apply: Interested candidates should send a resume and cover letter detailing their experience and fit for the role to We are excited to learn how you can contribute to the Neurophos vision and help us push the boundaries of optical computing.
