Senior Deep Learning Research Engineer

• Join Greyparrot to build the eyes of a circular economy, applying cutting-edge deep learning in messy, real-world environments where your input directly reduces the global carbon footprint. • Work as an architect of a sustainable future, with the autonomy to propose, discuss, and implement the best solutions for customers. • Report to the Head of Deep Learning, working within a focused DL team and collaborating with a dedicated Data team. • Interact regularly with the wider company to ensure technical alignment across the organisation.

• Bring 3+ years (5+ preferred) applying deep learning in industry settings. • Have experience applying the latest deep learning research in PyTorch. • Bring experience with at least two of active learning, semi-supervised learning, learning from noisy labels, and model robustness. • Have experience with architectures such as YOLO, ViT, and ResNet. • Write clear, efficient, and scalable code using Python and PyTorch. • Have experience with numpy, scipy, OpenCV, and Albumentations. • Bring an analytical, detail-oriented mindset with strong abstract thinking and a solid theoretical understanding of neural networks.

• Have experience in the waste industry. • Bring startup or scale-up experience. • Have built internal tools to automate research and analysis workflows. • Have experience integrating computer vision models into real-world production environments.

• Push the boundaries of deep learning by building on the latest research in object detection and classification. • Develop deep learning methods using best software development practices, training, analysing, and reporting model performance. • Develop internal tools to further automate research and analysis workflows.

• Earn a competitive London-based salary (band shared on application) plus an employee stock option scheme. • Work customised hybrid between office and home. • Take 25 days' holiday plus UK bank holidays (or statutory country-equivalent if higher), carrying over up to 3 unused days each year. • Get paid sick leave for physical and mental health needs, plus 1-1 mental health support and therapy through Spill. • Benefit from enhanced maternity, paternity, adoption, or shared parental leave. • Use a £500/year learning and development budget and a £500/year home office budget. • Enjoy unlimited healthy snacks in the office, summer Friday half-days, and a cycle-to-work scheme. • Work nomadically for up to 12 days a year within a 1–3 hour time difference.

Greyparrot is a London-based leader in AI waste analytics, on a mission to increase transparency and automation in waste management and accelerate the circular economy. Its camera systems and AI software are deployed in recycling plants and waste facilities worldwide to measure material flows and provide real-time waste analytics. The company's Analyzer units track and identify materials passing through recovery facilities, while its Deepnest platform gives brands direct access to how their packaging performs at end of life. By bringing transparency and accountability to a sector where waste data has been largely non-existent, Greyparrot is tackling a global waste crisis in which recycling rates remain around 10%.
