Sophie Wang is Vice President, System Engineering and Validation at Velodyne Lidar. She joined Velodyne in early 2019 and her team is responsible for all aspects of lidar and related systems validation and calibration. This includes confirming that our lidar sensor designs meet operational and technical specification requirements under all relevant operating conditions and environments. It also includes certifying the readiness of our lidar sensors to pass through the New Product Introduction (NPI) phase and move to production.
Sophie holds a PhD degree in Optical Engineering from the University of California, Santa Cruz. Prior to joining Velodyne, she spent more than ten years in the telecommunications industry in a few different roles, from engineer to engineering management positions. These positions ranged across a vertically integrated organization: from chip to subassembly to module level, with a focus on solving all kinds of product engineering issues to effectively bridge design and successful volume production.
We chatted with Sophie to learn more about her and her work at Velodyne.
Sophie: My team’s mission is to calibrate, test and validate all of Velodyne’s new product design and design changes. We work closely with the product design, development and manufacturing groups to ensure we develop high-quality lidar sensors that meet different levels of specification and reliability requirements, and successfully transfer them to our manufacturing partners for volume production.
As the commercial and product management teams are bringing in new exciting business opportunities, a product validation plan and requirement is often a critical element for sustained partnership. The system validation team will develop and drive product validation plans together with project management teams and adjacent teams.
Sophie: We have a few different roles in the system engineering and validation group. Depending on which role we are playing on a specific day, we can be found doing intrinsic lidar distance and reflectivity calibration, simulating optical stray light impact to lidar performance, or characterizing lidar field of view and range accuracy performance across different settings.
We plan and execute validation tests of new design or process changes, travel to a third party test lab to test the robustness of our lidar, write testing scripts, analyze and report the validation results. Our team also conducts root cause analysis of production and validation failures in development phase. We are involved in discussions with cross functional groups for corrective actions and improvement plan execution to constantly make our lidar better.
Sophie: It is our mission to validate and certify the performance and reliability of our lidars. We hold a high-quality standard to all of our sensors through EVT (Engineering Validation Test) and DVT (Design Validation Test) processes. In these processes, sensors in different product development phases are function/performance and reliability/robustness tested according to international road vehicle standard or other application based industrial standards.

Sophie: It was awesome and very encouraging to see many women engineers and engineering leaders in this traditionally male-dominant field! We may continue to have less women representatives in autonomous industry for a long way to come.
However, in my humble view, gender should never be a variable in the function of personal impact and capability in professional world. I am infinitely appreciative to all my managers and colleagues that I was fortunate to have had the pleasure to work with, for they have helped to shape my view.
Sophie: I am a curious person with a long list of things and places that I’d like to try and explore outside the work life. But as a mom of two (soon to be 8 and 12), I find myself always short of a few hours for this and that. Yeah, that’s just an excuse.
I love nature and believe in a nature fix. As such, I’ve enjoyed many of the Bay Area hiking trails with friends and family, although I often have to beg or threaten a little to get the kids to agree to go hiking. They do always end up having a great time once outside!
Despite the COVID-19 pandemic, I had the luxury (thanks to the support of my family) to fly to Oregon this summer, met with my hiking group and hiked the beautiful Mount Rainier (my favorite National Park) and a few other surrounding places. I also find yoga very restoring and have been practicing it for many years.
