Join to apply for the
Senior Production Test Engineer – LiDAR
role at
Voyant Photonics Voyant Photonics, based in New York City, is transforming machine perception with LiDAR devices that are compact yet powerful. Our sensors leverage silicon photonic chips to deliver high-precision range, velocity, and reflectivity in a scalable, affordable form. Position Overview We are seeking a Senior Production Test Engineer to lead the development and implementation of scalable, high-throughput test infrastructure for both wafer-level production and end-of-line testing of LiDAR sensors. You will define and execute test strategies at multiple stages of manufacturing—wafer level for photonic devices and module/system level for LiDAR units—working closely with Systems, Photonics, Electrical, Firmware, and Manufacturing Engineering teams to ensure performance, yield, and reliability from prototype to volume production. Key Responsibilities Define and implement end-of-line test strategies for LiDAR sensors, validating system-level performance (range, velocity, reflectivity, etc.). Lead the development of photonic wafer-level test (WLT) strategies and tooling in collaboration with photonic design and foundry partners. Develop automated test fixtures and software to support both EOL and WLT in a production setting. Translate lab-level validation methods into robust and scalable production tests across optical, electrical, and mixed-signal domains. Partner with external contract manufacturers and test vendors to stand up and scale production test infrastructure; support factory bring-up and operator training. Drive test coverage, throughput, and cost optimization in both low- and medium-volume manufacturing. Lead root cause investigations for test failures across the stack and work cross-functionally to implement fixes. Own and continuously improve statistical process control (SPC), yield tracking, and test data analytics across the production lifecycle. Support reliability and environmental testing (e.g. thermal cycling, vibration, shock) for product qualification. Qualifications Bachelor’s or Master’s degree in Electrical Engineering, Optical Engineering, Physics, or a related discipline. 5+ years of experience in production test engineering with a focus on LiDAR systems, photonic components, or optical sensors. Proven expertise in system-level testing for LiDAR, imaging, or other complex electromechanical/optical systems. Hands-on experience developing and deploying automated test setups (Python preferred), including test instrumentation and DAQ systems. Proven track record in statistical process control, yield analysis, and high-volume data-driven decision-making. Demonstrated experience owning test strategy and implementation in a manufacturing or pilot-line environment. Familiarity with test methodologies for photonic integrated circuits or optical wafers (e.g., wafer probing, passive/active alignment, coupling efficiency). Experience interfacing with contract manufacturers and external test vendors. Preferred Skills Experience with FMCW LiDAR or coherent optical systems. Familiarity with photonic wafer-level test equipment and alignment automation. Exposure to MES systems, manufacturing analytics platforms, or test data infrastructure. What We Offer Competitive salary and meaningful equity package Unlimited PTO and paid company holidays Team events and company meetups Hybrid or remote work environment with monthly travel for remote employees Daily lunch provided in our NY office (Monday–Friday) Seniority level Mid-Senior level Employment type Full-time Job function Engineering and Information Technology Industries: Automation Machinery Manufacturing Note: This refined description retains core job information and removes non-essential boilerplate and extraneous postings while preserving the focus on responsibilities and qualifications.
