AI​/ML Software Engineer

Description
Title:
AI Software Engineer
Location:
Cartersville, GA (Qcells Cartersville Factory)
Department:
Smart Intelligence Team
The AI Software Engineer will design, develop, and deploy AI systems across Qcells’ solar manufacturing line - spanning ingot, wafer, cell, and module processes at the Cartersville (CTV) and Dalton (DLT) plants. The role covers two core areas: (1) deep learning‑based machine vision for automated defect inspection and quality control, and (2) AI agent systems that combine large language models (LLM), retrieval‑augmented generation (RAG), and real‑time process monitoring to support frontline engineers.

The engineer will own the full lifecycle from data collection and model training to production deployment and continuous improvement (MLOps).

• Build and maintain image datasets for inspection, including data collection, annotation workflows, and dataset versioning across cell and module processes
• Perform exploratory data analysis to extract statistics and actionable insights from vision inspection and process data
• Train and evaluate deep learning models for image classification, object detection, and instance segmentation (e.g., EL/AOI defect detection, over-kill and miss reduction)
• Develop advanced inspection architectures such as cascade (two-stage) inference for ambiguous defect verification
• Design and build AI agent systems using LLM and RAG pipelines (vector database, embeddings) for process Q&A, automated root‑cause analysis (RCA), and real‑time anomaly alerting (e.g., via messaging integrations such as Telegram)
• Deploy and integrate machine learning models into industrial equipment and inspection systems, including interfaces with manufacturing equipment, MES, and process databases
• Build and operate data pipelines connecting equipment, inspection images, and process parameters for correlation analysis and traceability
• Establish MLOps practices for model monitoring, retraining, and continuous performance improvement on newly generated production data
• Collaborate with process, equipment, and quality engineering teams to translate domain requirements into AI solutions

• Bachelor’s degree in a quantitative discipline (e.g., Computer Science, Statistics, Industrial Engineering, Mathematics, or a related field)
• 2+ years of relevant experience
• Professional experience applying machine learning to computer vision — specifically image classification, object detection, and instance segmentation
• Proficiency with Python and deep learning frameworks (PyTorch, Tensor Flow) and OpenCV
• Comfortable working across the entire machine learning lifecycle, from data gathering to model deployment
• Solid understanding of both classical computer vision algorithms and deep learning‑based solutions
• Ability to collaborate effectively with colleagues, customers, suppliers, and stakeholders from different technical backgrounds

• Experience building LLM / RAG‑based applications or AI agents (e.g., vector databases, embedding models, prompt engineering, agent orchestration)
• Experience in a data‑related role in a manufacturing industry
• Experience with network programming such as TCP/IP and SMB protocol
• Experience deploying and operating models in production (MLOps), including monitoring and retraining pipelines
• Familiarity with messaging or alerting integrations (e.g., Telegram, Slack) for operational notifications
