Senior Machine Learning Software Engineer, On-Cloud

Seattle, Washington, United States

Metropolis is an artificial intelligence company that uses computer vision technology to enable frictionless, checkout-free experiences in the real world. Today, we are reimagining parking to enable millions of consumers to just “drive in and drive out.” We envision a future where people transact in the real world with a speed, ease and convenience that is unparalleled, even online. Tomorrow, we will power checkout-free experiences anywhere you go to make the everyday experiences of living, working and playing remarkable – giving us back our most valuable asset, time.

We are seeking a Senior Machine Learning Software Engineer to lead the development of advanced multi-camera perception and localization systems with an integrated focus on image-based search, vector database integration, and re-ranking strategies. You will design and build algorithms that combine object tracking, scene understanding, and cross-camera reasoning with scalable retrieval systems to power high‑precision localization and visual matching across large-scale deployments.

This role requires strong expertise in computer vision, real‑time systems, and search infrastructure, with a focus on turning visual data into actionable spatial intelligence.

• Design and implement algorithms for multi‑camera object detection, classification, and persistent tracking
• Build scene understanding modules to extract landmarks, spatial layout, and semantic context from image streams
• Develop cross‑camera fusion and localization methods for consistent identification and positioning of objects
• Architect and deploy visual search systems using vector databases (e.g., Open Search, FAISS, Milvus) for image-based retrieval and matching
• Design and implement re‑ranking techniques to improve retrieval precision based on context, metadata, and scene cues
• Create tools and metrics to evaluate retrieval quality, localization accuracy, and perception robustness
• Collaborate across ML, backend, and infrastructure teams to ensure scalable, real‑time deployment
• Investigate system‑level issues, drive debugging efforts, and improve model and system performance
• Mentor junior engineers and contribute to long‑term vision for perception, localization, and image retrieval

• M.S. or Ph.D. in Computer Science, Robotics, Electrical Engineering, or a related field
• 5+ years of industry experience in computer vision, image retrieval, or perception systems
• Strong background in object detection, tracking, and scene understanding using multi‑camera inputs
• Deep understanding of vector‑based retrieval systems and experience with Open Search, FAISS, or similar tools
• Proficiency in Python or C++, with hands‑on experience in PyTorch, Tensor Flow, and OpenCV
• Experience in building large‑scale image retrieval pipelines, including feature extraction, indexing, and search optimization
• Knowledge of multi‑view geometry, and cross‑camera identity association
• Experience evaluating and tuning re‑ranking strategies using contextual and multi‑modal signals
• Exposure to cloud‑based deployment of search systems (e.g., Open Search cluster tuning, sharding, replication)
• Experience with edge deployment of perception pipelines (e.g., Jetson, Qualcomm)
• Publications or patents in the fields of visual search, localization, or multi‑camera perception

The anticipated base salary for this position is $ USD to $ USD annually. Additional compensation may include stock options, bonus plans, and a comprehensive benefits package including health, dental, vision, 401(k), and disability coverage.
