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 8 years of experience in photonic devices, photonic integrated circuits, and semiconductor physics.
  • Strong understanding of silicon photonics.
  • 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.
  • Strong problem-solving skills, particularly for problems without obvious solutions.
  • Candidates should have capacity to comply with federally mandated U.S. export control requirements.

Responsibilities

  • Engage with a cross-functional team to design and deliver a successful high-volume laser and optical product.
  • Collaborate with product and architecture teams to drive new laser and photonics concepts.
  • Work closely with hardware and software teams to translate high-level module product requirements and architecture specifications into a detailed engineering execution plan.
  • Resolve design and manufacturing challenges for innovative high-performance laser solutions.
  • Collaborate across electronics, photonics, mechanical, thermal, and package-design engineering disciplines to build photonic systems, control algorithms, photonic integrated circuits, and control application-specific integrated circuits that meet performance, power, and production requirements.
  • Collaborate with control-system and test engineers to define production test and validation protocols, characterize components, and debug test results from prototype level through validation.
  • Work with external vendors to ensure timely development and delivery of key processes and components.

Desired Qualifications

  • Strong understanding of laser physics.
  • Experience with lasers or silicon photonics for datacom applications.
  • Experience with control systems and systems engineering.
  • Experience working in a high-volume manufacturing environment.
  • Demonstrated technical leadership of a cross-functional team.

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.
