About the Job

Requirements

  • A Ph.D. in Photonics, Electrical Engineering, Applied Physics, or a related discipline, with at least 3 years of relevant post-degree experience or equivalent.
  • A minimum of 3 years of experience in photonic devices, photonic integrated circuits, and semiconductor physics.
  • A strong understanding of silicon photonics or hands-on circuit design experience.
  • Experience collaborating closely with cross-functional engineering teams, including photonics design, packaging, thermal, systems engineering, and firmware.
  • Ability to convey complex technical concepts to technical and non-technical stakeholders.
  • Demonstrated problem-solving skills, particularly for problems without obvious solutions.
  • Capacity to comply with federally mandated U.S. export control requirements.

Responsibilities

About the Company

Lightmatter

Photonic computing hardware for AI acceleration

Lightmatter develops photonic computing hardware that accelerates AI workloads using light-based processors. Its photonic supercomputers run AI tasks faster and use far less energy (about 10x faster and 90% less energy) than traditional electronic systems. The company differentiates itself by focusing on electro-photonic systems and practical AI acceleration for AI and autonomous vehicle workloads, working with universities and selling hardware, software licenses, and partnerships. Its goal is to bring scalable photonic computing to market so AI and self-driving applications can run faster, more efficiently, and at larger scale.
