Where others see a simple need for grocery delivery, we see exciting complexity and endless opportunity to serve the varied needs of our community. Overview At Arpalus, recently acquired by Instacart, we build AI-powered computer vision and AR technology that turns a phone camera into a precise sensing tool - real-time object detection, scanning, and spatial understanding shipped as a mobile product. Our tech runs on real devices, in real environments, under messy real-world conditions. As a Principal Computer Vision Engineer, you'll join our core AI team and help craft best-in-class perception systems that power our real-time retail analytics. You'll solve genuinely hard problems in computer vision, bridging the gap between cutting-edge research and highly optimized production pipelines. Responsibilities: - Architect and Own: Drive the evolution of our core computer vision pipelines, taking algorithms from initial research and training through to highly optimized production deployment. - Blend Classic & AI: Design and implement robust classic computer vision algorithms alongside deep learning architectures to solve complex spatial, alignment, and tracking challenges. - Model Development: Train, evaluate, and fine-tune state-of-the-art deep learning models for object detection, classification, and advanced segmentation. - Optimize for Production: Build and optimize high-performance inference pipelines in Python and C++, leveraging optimization tools like TensorRT and CUDA to ensure low-latency execution. - Technical Leadership: Drive technical excellence across the AI stack, evaluating new architectures, standardizing our training methodologies, and making pragmatic tradeoffs between accuracy, speed, and compute constraints. - Deliver End-to-End: Handle technical design, clean architecture, implementation, observability, and iterative improvements of our perception engine. Minimum Qualifications: - 6+ years of industry experience in computer vision, machine learning, or a related field. - Deep expertise in classic computer vision techniques, including strong practical knowledge of optical flow, multi-view geometry, feature matching, and homography estimation (e.g., using OpenCV). - Strong foundational understanding of modern deep learning architectures, specifically for object detection, image classification, and semantic/instance segmentation. - Production-level programming skills in Python. - Extensive hands-on experience with PyTorch and building scalable model training and evaluation pipelines. - Proven track record of optimizing complex algorithms for deployment in resource-constrained or real-time environments. Preferred Qualifications: - Familiarity with state-of-the-art segmentation frameworks and zero-shot/foundation models (e.g., SAM, Mask2Former, Grounding DINO). - Experience working alongside mobile teams to integrate computer vision models into native SDKs (iOS/Android). - Experience translating computer vision algorithms into Apple frameworks and iOS. - Background in retail tech or AR-based scanning applications. ## Skills ### Required - computer vision - machine learning - Python - PyTorch - OpenCV - deep learning - object detection - image classification - semantic segmentation ### Nice to have - state-of-the-art segmentation frameworks - zero-shot/foundation models - SAM - Mask2Former - Grounding DINO - iOS - Apple frameworks - retail tech - AR-based scanning applications --- Source: [Apply at job-boards.greenhouse.io](https://job-boards.greenhouse.io/instacart/jobs/8155140?utm_source=yubhub.co&utm_medium=jobs_feed&utm_campaign=apply)
