About the Job

Requirements

  • Machine Learning fundamentals including areas related to search relevance, ranking algorithms, or information retrieval.
  • Strong programming proficiency in Python, C++, Go, or Java with a focus on building, scaling, and maintaining robust backend infrastructure.
  • Demonstrated ability to analyze code, system architecture, and data pipelines to improve execution speed and resource efficiency.
  • Experience handling and processing high volumes of data, particularly unstructured formats like image and video files.

Responsibilities

  • Optimize Search Infrastructure: Analyze and refactor existing image and video search indexing pipelines to maximize computational efficiency and minimize operational costs.
  • Build Iterative Search Features: Design and implement a feedback-loop mechanism that captures positive and negative signals from previous search rounds to dynamically refine and improve search accuracy.
  • Develop Smart Sampling Strategies: Overhaul the indexing sampling strategy to intelligently select data based on contextual factors such as predefined critical events, geographic location, and surrounding environmental conditions.
  • Cross-Domain Collaboration: Bridge the gap between machine learning models and backend infrastructure to ensure search systems are both highly accurate and horizontally scalable.

Desired Qualifications

  • Computer vision experience: familiarity with image and video processing techniques, feature extraction, or working with vector embeddings.
  • Active learning and relevance feedback: prior experience building human-in-the-loop systems, reinforcement learning, or systems that actively use user feedback to train or tune models.
  • Search and indexing tools: hands-on experience with vector databases (e.g., FAISS, Milvus) or large-scale search engines (e.g., Elasticsearch, Solr).
  • Contextual data integration: experience working with geospatial data (GIS), temporal event logging, or incorporating external metadata (like environmental factors) into datasets.

About the Company

PlusAI

Builds AI driving systems for commercial trucks

PlusAI develops AI driving software for commercial trucks, working with vehicle manufacturers and logistics partners to automate freight transport. Its SuperDrive system combines sensors, onboard computing, and AI models to understand roads, plan maneuvers, and control a truck within defined operating conditions. Truck manufacturers integrate the software into their vehicles, and PlusAI engineers develop and validate the virtual driver for use on freight routes. It also sells autonomous-driving data and development tools through HyperFoundry, and plans to charge for SuperDrive according to truck usage. PlusAI was founded in 2016 and is headquartered in Santa Clara, California.
