TerraClear applies artificial intelligence, robotics, and world-class mechanical design to solve some of the most data deficient and labor intensive jobs on the farm. These technologies are rapidly transforming agricultural intelligence, allowing farmers to make faster and more informed decisions that translate into highly precise actions and more productive farms. Our first application solved one of the most disliked tasks on the farm: clearing rocks. The annual emergence of news rocks impacts nearly half of farms in North America, slowing farming, damaging equipment, and causing downtime during seeding and harvesting. Solving this problem frees farmers to focus on higher-value tasks and brings their operations into a new era of farming. Leveraging our commercial success in rocks, we are now expanding our core technologies to new farm applications including the precise management of weeds, pests, disease and overall plant health. Our team is tight-knit and believes in the power of teamwork. We value learning directly from the farmers we serve, getting our hands dirty, and tackling tough challenges together. You will thrive at TerraClear with a positive attitude, a collaborative mindset, a healthy dose of grit and a passion for solving real-world problems. Machine Learning Engineer Remote Position Role As a Machine Learning Engineer, you will design, train, evaluate, and deploy deep learning models for real-world computer vision applications across mapping intelligence and robotics systems.
