  • Potentially developing a new design and iterating on current designs
  • Implementation of network using current frameworks (PyTorch and TensorFlow)
  • Training using local and cloud compute
  • Deployment and monitoring of continually retrained models
Understanding of existing segmentation techniques (such as detectron) Perception
  • Competent in the manipulation of point clouds
  • Oversight on all automated robot perception
  • Calibration
  • Marker detection based visual techniques
  • 3D, point cloud-only calibration
  • Refinement techniques and benchmarking
  • Designing lab & field experiments that prove efficacy of your proposed improvements - "hypothesis-driven development"
  • PhD in a technical field (involving machine learning, computer science, robotics, physics, electrical engineering or equivalent), ..or recent masters in very related field
  • Working knowledge of PyTorch or similar frameworks
  • Experience with
  • implementing numerical methods and data visualisation
  • ROS
  • SQL/data retrieval
