LiDAR Test & Calibration Engineer - Mountain View, CA, United States
$103,900 - $140,600 USD yearly
Originally posted 24 July 2026 by the employer.
About the role
This role is responsible for developing, optimizing, and supporting manufacturing test and calibration processes for LiDAR sensors in a high-volume production environment. You will ensure units meet performance, quality, and reliability specifications through automated testing, calibration, and data analysis on silicon photonics 4D LiDAR modules.
What you'll do
- Develop, validate, and maintain manufacturing test and calibration processes for LiDAR sensors. - Work with suppliers to design and optimize automated production test stations, fixtures, and calibration equipment. - Define production test sequences, acceptance criteria, and calibration algorithms. - Analyze LiDAR performance metrics including range accuracy, precision, SNR, signal intensity, point cloud quality, and receiver sensitivity. - Perform root cause analysis of manufacturing failures and implement corrective actions to improve first-pass yield (FPY) and overall equipment effectiveness (OEE). - Support EVT, DVT, PVT, and Mass Production (MP) builds, and integrate test equipment with Manufacturing Execution Systems (MES).
What you'll need
- 1–3 years of experience (or equivalent academic project experience) developing test processes and infrastructure for optoelectronic products such as LiDAR, laser-based sensors, optical systems, cameras, or imaging systems. - Strong programming abilities in Python. - Computer operating system and networking skills, including command-line tools and LAN troubleshooting. - Foundation in physics and signal processing fundamentals to understand 4D LiDAR and manufacturing variability impacts. - Familiarity with statistical analysis and Statistical Process Control (SPC) techniques. - Ability to travel internationally up to 25% of the time.
Nice to have
- Hands-on experience with electro-optical sensor systems. - Knowledge of photonics, optics, and laser systems. - Experience with robotic automation and industrial manufacturing equipment. - Exposure to production testing environments for electro-optical sensor systems. - Knowledge of software engineering processes, including version control, release engineering, test-driven development, and Agile methodologies. - Familiarity with automotive LiDAR performance requirements. - Bilingual fluency in Spanish or Korean.
