How to Apply for Senior Deep Learning Research Engineer

at greyparrot

🏢 About greyparrot

Greyparrot is pioneering AI-driven waste recognition technology to revolutionize recycling efficiency and create a cleaner planet. Unlike generic AI companies, they focus specifically on solving real-world environmental challenges through computer vision, making work here both technically challenging and socially impactful. Their mission-driven approach attracts engineers who want their deep learning expertise to contribute directly to sustainability.

About This Role

As a Senior Deep Learning Research Engineer at Greyparrot, you'll push boundaries in object detection and classification specifically for waste recognition, directly improving recycling accuracy. You'll develop and implement cutting-edge deep learning methods using PyTorch while building internal tools to automate research workflows. This role is impactful because your models will be deployed in real-world waste processing facilities, directly reducing landfill waste and increasing recycling rates.

💡 A Day in the Life

A typical day involves experimenting with new deep learning architectures for waste detection, analyzing model performance on challenging waste datasets, and developing tools to streamline the research pipeline. You'll collaborate with the team to implement research papers into production-ready code while ensuring models maintain robustness against the variability of real-world waste streams.

🎯 Who greyparrot Is Looking For

  • Has 3-5+ years of industry experience applying deep learning with PyTorch, specifically in object detection/classification domains
  • Demonstrates hands-on experience with at least two of: active learning, semi-supervised learning, learning from noisy labels, or model robustness - particularly relevant for messy real-world waste data
  • Has practical experience implementing architectures like YOLO, ViT, or ResNet for real-world applications, not just academic projects
  • Can show examples of writing clean, scalable Python code with PyTorch, numpy, OpenCV, and Albumentations for production-ready systems

📝 Tips for Applying to greyparrot

1

Highlight specific projects where you applied deep learning to messy, real-world data (similar to waste recognition challenges)

2

Include metrics showing how your models improved performance in production environments, not just research settings

3

Demonstrate experience with the exact technologies mentioned: PyTorch, OpenCV, Albumentations - not just generic ML frameworks

4

Show how you've worked with at least two of their specified research areas (active learning, semi-supervised learning, etc.) with concrete examples

5

Tailor your resume to emphasize waste/industrial applications or similar challenging real-world computer vision problems

✉️ What to Emphasize in Your Cover Letter

["Explain why you're specifically interested in applying deep learning to environmental sustainability and waste recognition", 'Highlight your experience with PyTorch and the specific architectures mentioned (YOLO, ViT, ResNet) in production settings', "Describe how you've handled noisy data or implemented robust models - crucial for waste recognition where labels can be imperfect", 'Mention any experience automating research workflows or building internal tools, as this is explicitly mentioned in the job description']
