About the Job

Requirements

  • A Master's degree in Photonics, Physics, Electrical Engineering, or a related field is required.
  • At least 6 years of proven experience in silicon photonics test development is required.
  • Industrial experience supporting new product introduction and volume production is required.
  • Understanding of silicon photonics components and circuits is required.
  • Experience working with design teams to define test cells for model feedback and validation is required.
  • Hands-on experience characterizing and testing photonics components and circuits is required.
  • Direct experience in high-speed photonic device testing and familiarity with test equipment such as AWG, DCA, DSO, PNA, and LCA are required.
  • Experience automating test systems using Python, C#, or other languages is required.
  • Ability to identify and solve issues during the testing process is required.
  • Ability to convey complex technical concepts to technical and non-technical stakeholders is required.
  • Capacity to comply with federally mandated U.S. export control requirements is required.

Responsibilities

  • Work with architecture and design teams to understand the technology and conceptualize characterization and test techniques that provide feedback for design model validation.
  • Architect test concepts and platforms, establish design-for-test rules, and provide feedback early in the technology concept phase.
  • Create detailed test-plan documentation and ensure timely execution.
  • Define, develop, and set up wafer-, package-, and system-level tests for silicon photonics products.
  • Develop test software for test execution, data analysis, and parameter extraction.
  • Work with vendors to specify and procure test equipment.
  • Set up and operate optical equipment such as tunable lasers, power meters, polarization synthesizers, OBR/OVA, and high-speed test equipment.
  • Engage with silicon and platform validation teams and bridge gaps between test and validation teams.
  • Work with OSAT teams to define, validate, and refine test techniques for high-volume manufacturing.
  • Work with the reliability team to address pre- and post-stress testing needs.
  • Keep up to date with developments in silicon photonics technology and testability.

Desired Qualifications

  • A PhD in Photonics, Physics, Electrical Engineering, or a related field is preferred.
  • At least 2 years of photonic component or circuit design experience is preferred.
  • Exposure to system link bring-up is preferred.

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.
