Senior Software Engineer – Frontend (Geospatial & Computer Vision)

Company OverviewThreeV Technologies, Inc. is an early-stage venture backed startup. We’re developing a Multi-Sensory Asset Intelligence Platform (MSAIP) to revolutionize asset heavy industries like Power & Utilities, Renewables, and Public Infrastructure. Our goal is to become the B2B Perplexity AI for the physical world. The ThreeV platform uses frontier AI techniques like customized Large Language Models, as well as applying the latest computer vision model architectures to drastically improve the end-to-end inspection process. This allows customers to cut operations & maintenance costs, streamline inspection decisions, and improve data accuracy to prevent asset failures. Global high profile safety incidents like wildfires over recent years underscore the urgent need for our platform, making it not just innovative but essential.Job SummaryWe’re looking for a Senior Software Engineer - Frontend (Geospatial & Computer Vision) to own and evolve ThreeV’s web platform and help define how computer vision and spatial data are translated into intuitive, performant product experiences.This is a hands-on senior IC role for someone who is equally comfortable fixing frontend bugs, building core product features, and implementing advanced visualizations such as computer vision overlays (bounding boxes, segmentation masks, metadata) and layered map-based views.You’ll work directly with our Platform and Machine Learning teams to improve and expand our Inspection Platform while leading frontend development across the broader product suite.
