Job(岗位): Laser and Sensor Test Engineer

Type(岗位类型): Operations

Citys(岗位城市): Sunnyvale, CA | Redmond, WA

Date(发布日期): 2022-3-28


The Laser and Sensor Test Engineer applies the highest level of skill and knowledge of laser optics, imaging, metrology, and optical-/electrical-based sensors (health, motion, magnetic, environmental) in architecting test/calibration stations for consumer electronics devices on a subassembly and system level.

You will drive conceptual test system hardware design with technology groups in the early product exploration stage and validate first article design in the lab. You will lead the end-to-end development of software and hardware integration, including test flow, instrument control, robotics/motion control, data capture and process, and integration of advanced algorithms with third-party partners. You will be an optical or electrical engineer expert for the team for consultation and also to design quick prototypes to aid test station validation. You will be leading in documenting and troubleshooting station hardware/software issues on test equipment and systems and bridge to production.

The ideal candidate is a self-driven individual working in a cross-functional team environment and will be responsible for planning the design, development, and implementation of factory test/calibration systems. You will enforce manufacturability, testability and ensure cost-effective designs are implemented for testing and automation systems, software, and equipment.

This position will have responsibilities for NTI (New Technology Introduction) and NPI test development and bridge to sustaining support of production. You must be responsive, flexible, and able to succeed within an open collaborative peer environment. We are looking for someone with a productive mindset who can apply their expertise to solve problems in creative, insightful ways.


Bachelor’s degree in Physics, Electrical Engineering, Optics or related field.

2+ years of experience in developing test/calibration solutions in a consumer electronics or related field.

2+ years of experience in at least one of the two areas: Optical metrology (spectrometer, radiometer, imaging optics, color sensor, etc.) or High-precision sensitive electrical signal measurements, including noise shielding and suppression.

Experience with designing complicated test systems integrating instruments, mechanical motion, electrical controls, and test software.

Experience with programming languages such as Python, C/C++, and data processing tools such as MATLAB, JMP and Minitab.

Experience in statistical methods (distributions, SPC, Cpk, etc.) for data analytics.


Develop and deploy advanced manufacturing-ready laser and sensor test stations for Meta AR/VR consumer electronics products.

Coordinates third-party vendors in designing, fabricating and developing test systems.

Develop and deploy end-to-end test software including test sequence, motion stage/robotics control, image capturing/processing and data transaction interface to defined IT infrastructure.

Drive third-party vendors to develop and customize instruments (including camera, lens, sensor, light source, etc.) that meet the unique requirements of test systems.

Analyze, evaluate, design, integrate and test the first article fixture to meet specification and proof of concept.

Lead functional technology groups and drive cross-functional decisions on test development and architecture.

Validation of test SW/FW releases, including repeatability and negative testing, and coordinate SW upgrades with fixture integrator and CM/JDM partners.

Troubleshoot and debug test systems and automation solutions from a software and hardware perspective in full autonomy.

Support failure analysis on systems and use data to improve test strategies and processes.

Serve as subject matter expert for the test team for sensitive electrical and/or laser measurements.

Work with vendors and firmware/electrical design team to design prototype or driver boards (e.g. for camera or sensors) and FPCs for rapid prototypes.

Travel up to 25%, includes domestics and International travels for prototype builds support, mass production sustaining, and collaboration with R&D teams.

Additional Requirements(额外要求)

Master/Ph.D. in Physics, Electrical Engineering, or Optics.

Experience with laser safety classification and the required tests.

Experience with health sensors (e.g. heart rate, oximeter), electrical-based sensors (e.g. electromyography), optical-based sensors (e.g. ambient light), or environmental sensors (e.g. magnetometer, proximity).

Experience with standard communication buses (I2C, SPI, UART, etc.).

Software skills: Python proficiency, image processing algorithms.

5+ years experience with factory tests for consumer electronics products for NPI and mass production.

Experience with managing multiple third-party vendors from evaluation, down-selection, and driving deliverables to meet project requirements.
