About the role

Principal Computer Vision Engineer role at Arpalus (now part of Instacart) focusing on building real-time perception systems for mobile, real-world retail analytics. Blends classical CV with deep learning, leads technical strategy, and ships observable algorithms at scale in a hybrid(work onsite 3 days/week) environment.

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.

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.
