Staff Photonics Test Engineer (Mountain View)

Lightmatter builds chips that enable extreme-scale artificial intelligence computing clusters. If you're a collaborative engineer or scientist who has a passion for innovation, solving challenging technical problems and doing impactful work like building the world's first optical computers, consider joining the team at Lightmatter!

In this role as a part of the product engineering team you will be focused on High Volume Manufacturing (HVM) testing, developing novel wafer and package level testing strategies of Lightmatter’s Silicon Photonics products. You will also help in setting up validation capabilities and carrying out validation tests. You will be expected to support customer deployment and related technical issues.

Responsibilities

• Work closely with architecture, design, product engineering, and customers to understand the test needs.
• Create test plan documentation, feasibility analysis, and provide feedback early on during the design phase.
• Define, develop, and setup of wafer and package level tests for Lightmatter silicon photonics products.
• Develop test software to enable test execution, data analysis, and parameter extraction.
• Work with vendors to specify and procure test equipment.
• Setup and operate a range of optical equipment such as lasers, DCA, BERT, OBR/OVA, and switches for HVM testing.
• Work closely with Operations on wafer sort/package test timelines.
• Engage with silicon and platform validation teams and bridge any gaps between the test and validation teams.
• Help enable reliability teams for pre and post stress test needs.
• Keep up to date with the latest developments in Silicon Photonics technology and testability.

Requirements

• Master’s in Photonics, Physics, Electrical Engineering or a related field.
• 6+ years of proven experience in silicon photonics test development including wafer level test experience.
• Understanding of photonic integrated components and circuits.
• Hands-on lab experience in optoelectronics link testing of photonics chips, components, and devices.
• Experience working with test equipment including lasers, VNA, switches, spectrum analyzers, high-speed oscilloscopes (DCA), BERT, source-meter units, or OBR etc.
• Proficiency in Python for test automation.
• Strong analytical and problem-solving skills to identify and solve issues during the testing process.
• Ability to convey complex technical concepts to both technical and non-technical stakeholders.

Preferred Qualifications

• Ph.D in photonics, Physics, Electrical Engineering or a related field with 3 years of silicon photonics test development including wafer level test experience.
• Experience working in HVM environment from NPI to Mass Production.
• System level validation experience of silicon photonics products.
