Staff Silicon Photonics Test Engineer

Job Title

Staff Silicon Photonics Test Engineer

Role Summary

Lead hands-on engineer responsible for device and PIC characterization, test execution at the bench, and lab/measurement infrastructure at Lumilens. The role sets test methodology, owns transitions from R&D to production test flows, and mentors junior engineers.

Experience Level

Senior — typically 8+ years of relevant experience.

Responsibilities

Primary technical and leadership responsibilities:

• Define and own characterization strategy for devices and PICs (EO, OE, OO) at chip and wafer level.
• Architect and lead high-speed measurements (bandwidth, BER, eye diagrams, etc.).
• Establish best practices for test automation frameworks and measurement routines using LabVIEW and/or Python.
• Lead wafer probing, optical alignment, and test setup bring-up.
• Perform root-cause analysis and resolve complex test and measurement issues.
• Analyze measurement data and provide actionable feedback to design and process teams.
• Own die sorting, yield improvement initiatives, and transition test flows from R&D to production.
• Mentor and provide technical direction to junior test engineers; collaborate cross-functionally on test requirements and roadmaps.

Requirements

Must-have technical skills and experience. Education items are listed under Education Requirements below.

• Deep, hands-on expertise in photonics device testing and optical lab work.
• Experience with high-speed measurement equipment: VNA, high-speed oscilloscopes, BERTs, and related instrumentation.
• Strong understanding of optical communication systems and measurement techniques.
• Advanced proficiency in LabVIEW (preferred) and/or Python for test automation; experience with instrument control (VISA/SCPI).
• Extensive experience with optical alignment, fiber handling, and wafer probing.
• Proven ability to design, build, and scale lab test infrastructure and measurement workflows.
• Detail-oriented leader with a track record of mentoring engineers and driving execution in fast-paced environments.
• Experience taking test processes from R&D to production scale (preferred).

Education Requirements

Bachelor's degree or higher in Electrical Engineering, Physics, or a related technical field.
