How to Apply for CVML Engineer, See & Spray

at Blue River Technologies

🏢 About Blue River Technologies

Blue River Technologies is pioneering sustainable agriculture through robotics and AI, specifically targeting precision farming to dramatically reduce chemical use and waste. Their See & Spray technology represents cutting-edge computer vision and machine learning applied to real-world environmental challenges, making this an opportunity to work on meaningful technology with tangible ecological impact.

About This Role

As a CVML Engineer for See & Spray, you'll be responsible for the full lifecycle of deep learning models—from training and fine-tuning to error analysis and dataset improvement—specifically for agricultural weed detection and spraying systems. This role directly impacts farm sustainability by optimizing model performance to reduce chemical usage while maintaining crop health.

💡 A Day in the Life

A typical day involves analyzing model performance metrics from recent field tests, using weak supervision techniques to clean and enrich weed detection datasets, fine-tuning PyTorch models based on error analysis, and updating dashboards to visualize model improvements for cross-functional teams. You'll collaborate with robotics engineers to understand field constraints while iterating on models that directly impact chemical reduction in farming.
