About the Job

Requirements

  • A Bachelor's degree in Electrical Engineering.
  • At least 8 years of related experience in system-level electrical design, including successfully taking several products from concept to production.
  • Proficiency in schematic design using Cadence, Mentor, or Altium tools; Altium is preferred.
  • In-depth knowledge of voltage regulator modules, high-speed serializer/deserializer interfaces, central processing units, and interfaces or protocols such as PCIe, Ethernet, QSPI, I3C, and I2C.
  • At least 5 years of experience in laboratory experimentation, non-intrusive circuit debugging, and leading cross-functional integration teams.
  • Experience working with thermal solutions for integrated circuits and their board-level systems.
  • Familiarity with Product Lifecycle Management tools such as Oracle Agile, Arena, or Omnify PLM, and understanding of bill of materials and engineering change order management.
  • Capacity to comply with federally mandated U.S. export control requirements.

Responsibilities

  • Collaborate with the system architect and technical leads to define system-level hardware requirements and specifications.
  • Design power, memory, and interconnect circuits in analog and digital domains.
  • Identify electrical and optical components that fit the application based on specifications provided by the integrated circuit and photonics engineering teams.
  • Develop conceptual designs, physical models, and simulations of chip modules and systems, beginning with fundamental concepts and system considerations.
  • Oversee and review printed circuit board layout designs and provide complete, detailed electrical constraint rules.
  • Ensure boards and systems are manufacturable using the latest technologies, with high yield and robustness.
  • Qualify chip and system electrical properties.
  • Perform laboratory validation of boards and systems.
  • Lead integration with mechanical, software, integrated circuit, and other related teams.
  • Support contract manufacturing during prototype and production phases to resolve issues.
  • Work with component vendors and other supply partners.
  • Research new components, processes, and technologies to meet product goals.

Desired Qualifications

  • Experience designing electrical systems for networking or similar industries.
  • Knowledge of integrated circuit layout and designing a carrier printed circuit board assembly for it.
  • Knowledge of common manufacturing and design processes.
  • Familiarity with Systems Engineering principles.
  • Familiarity with 3D mechanical computer-aided design tools such as Solidworks or AutoCAD.

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.
