Staff Electrical Engineer

工作内容

Key responsibilities:

• Design and develop 3D sensing laser and package test board, including schematic design, layout, high speed circuit simulation, PCBA build, bring up, and verification.
• Develop laser driver circuit and evaluation board reference designs for time of flight (TOF) and structure light applications.
• Perform laser and package characterization tests, including RF / high speed electrical and optical tests, test system build and calibration for optical and electrical characterization (LIV, high-speed / pulse testing, WL, far field, beam quality).
• Perform TOF and Lidar subsystem performance and tradeoff evaluation, including transmitter (laser and driver circuits), receiver (sensor and amplifier circuits) test and optimization, depth measurements and characterizations
• Data analysis, documentation and presentation of design and test data
• Support design integrated optical modules and subassemblies including laser, driver, sensor, and amplifiers etc., from concept, prototype, qualification to volume manufacturing for consumer, industrial, and automotive applications
• Work closely with PLM and FAE teams for customer technical support

Qualifications:

• Experiences in high speed circuit simulation, design and test.
• Experience in PCB layout is desirable
• Strong analytic and data analysis skills via Excel, Minitab and/or JMP is a plus
• Experience with circuit design and simulation, PCB layout tools, such as Cadence, Spice, HFSS, ADS, CST simulation tools is a plus
• Familiarity with TOF components such as semiconductor lasers (VCSEL or Edge emitter), optical components (lens, diffuser, DOE, etc.), pulsed laser driving electronics, APD and SPAD sensors, and TIA receiving electronics components.
• Knowledge on TOF system design, design tradeoffs, experiences on Lidar or dTOF module or subsystem product development
• Knowledge of optics and optical testing is desirable.
• Experience in conceptual design, product and component requirements definition, customer technical engagement, vendor interaction, sample prototyping, testing, and performance characterization
• Excellent written and oral communication skills
• BS degree with 10 years in electrical, optical or physical engineering. Experienced designer with master or PhD. in EE preferred.
