Job description

Ready to shape the future of autonomous technology right from the production floor? We are looking for a hands‑on Sr. Manufacturing Test Engineer to lead our calibration and end‑of‑line (EOL) test operations for cutting‑edge LiDAR systems in Pleasanton, CA. In this high‑impact role, you will bridge the gap between complex engineering requirements and reliable, high‑volume production by partnering with world‑class cross‑functional teams and global CM/EMS providers. If you thrive in fast‑paced environments, love diving into root‑cause analysis for electro‑optical hardware, and want to own the processes that ensure our tech is deployment‑ready, we want you on our team. Come help us scale the next generation of sensing technology from pilot builds to volume manufacturing!

Interview Process

We believe in full transparency. Here's what to expect before you apply.

• Interview On‑Site · 4 hours · Peer / Team Members

Responsibilities

• Own and support calibration and end‑of‑line (EOL) test processes for our LiDAR systems and subassemblies.
• Set up, validate, maintain, and improve production test stations, fixtures, and supporting processes.
• Execute test and calibration procedures during NPI, pilot builds, and volume production.
• Troubleshoot test failures and manufacturing issues and drive root cause analysis and corrective actions.
• Partner with CM/EMS providers and cross‑functional teams including Systems, Hard- ware, Quality, Reliability, and Operations to support production readiness and ongoing manufacturing.
• Drive yield improvement, test robustness, and continuous improvement initiatives across manufacturing test operations.
• Maintain test documentation, work instructions, and engineering change control records.
• Participate in DFT and DFM reviews to improve manufacturability, test coverage, and product readiness.

Requirements

• Bachelor’s degree in Electrical Engineering, Optical Engineering, Physics, Mechanical Engineering, or a related technical field.
• 8+ years of experience in manufacturing, production test, or test engineering, ideally in optics, sensors, automotive electronics, or similarly complex hardware environments.
• Hands‑on experience with automated test systems, lab instrumentation, and production fixturing.
• Strong understanding of electro‑optical systems, lasers, photodetectors (including APD and SPAD), and optical fundamentals
• Experience using data analysis and statistical methods to improve yield, reliability, and test performance.
• Ability to work effectively in a fast‑paced production or manufacturing environment.
• Willingness to support builds and issue resolution at world wide CM/EMS partner sites as needed

Nice to Haves

• Experience with LiDAR systems, optical sensors, or related electro‑optical products.
• Familiarity with laser‑based systems, photodetectors, and optical alignment processes.
• Exposure to automotive manufacturing, safety‑critical systems, or high‑reliability products.
• Experience working with contract manufacturers or EMS partners in a production
