Thinking about this job
Responsibilities
On the Computer Vision & Machine Learning team at GBG Plc in Atlanta, you'll design, implement, fine-tune, and optimize state-of-the-art ML and CV models (including CNNs, transformers, and vision-language models), rigorously evaluate them with appropriate metrics, and analyze data to improve accuracy, robustness, and reliability. You’ll support full ML lifecycles and MLOps practices—covering data preparation, training, deployment, monitoring, CI/CD, and troubleshooting production issues—while proactively enhancing models, workflows, tools, and features. You’ll also mentor junior engineers, participate in design reviews and Agile ceremonies, share knowledge across the team, and stay current on emerging ML and CV trends to deliver high-impact solutions in collaboration with engineering, product, and data stakeholders.
