Applied ML & Data Mining Engineer: Large-Scale Retrieval

PlusAI; Santa Clara (CA); On-site; USD 130,000 - 220,000; Full time

Job summary

PlusAI is seeking Software Engineers to advance data mining, retrieval, and ranking methods for autonomous-driving datasets. You will design, implement, and evaluate scalable pipelines handling fleet-scale imagery, video, and time-series data, delivering end-to-end mining products with Python APIs, TypeScript/React interfaces, and robust production systems.

The role welcomes candidates with ML or data-mining foundations who are eager to grow across scalable systems and the product stack.

Qualifications

• BS, MS, or PhD in Computer Science, Machine Learning, or a related technical field, or equivalent practical experience.
• Hands-on experience developing and evaluating machine-learning, data-mining, computer-vision, or information-retrieval methods with PyTorch or TensorFlow, including experimentation, error analysis, and principled metrics.
• Foundations for data-centric machine learning: an understanding of model uncertainty and evaluation, embeddings and similarity search, and how training-data composition shapes model behavior.
• Self-driven with a strong sense of ownership: a quick learner who is eager to take responsibility and drive projects forward end to end.

Responsibilities

• Develop and evaluate mining, retrieval, and ranking methods using signals such as model confidence, disagreement, embeddings, anomalies, temporal behavior, and learned representations.
• Build and evolve semantic image/video/scenario search, including text-to-image/video and image-to-image or video-to-video retrieval, vector search, metadata and temporal or spatial filters, task-specific ranking, and search quality, freshness, latency, and reliability.
• Build and operate distributed mining, inference, and indexing pipelines over fleet-scale imagery, video, time-series, and autonomy-system data, including GPU batch inference, embedding generation, reproducible candidate datasets, and reliable index refreshes.
• Design and ship mining products end to end: Python APIs and services, relational data models, asynchronous jobs, modern TypeScript/React search and review experiences, deployment, access control, testing, observability, and production reliability.
• Ensure that your work is performed in accordance with the company’s Quality Management System (QMS) requirements and contribute to continuous improvement efforts.
