• Strong background in TensorFlow or PyTorch; Python and packages/libraries related to computer vision or graphics; evidenced by the development of advanced applications in image/video/graphics processing or computer vision (minimum of 3 years of experience for ML engineer, minimum 5 years for Senior ML engineer).
• Evidence of leading technical developments by at least 1 research publication in a top‑tier conference like CVPR, ECCV, ICCV, SIGGRAPH or similar.
• Solid background in one or more of the following: (i) neural network architectures, evidenced (for example) by knowledge of how to formulate and test advanced loss functions in neural network design; (ii) design and test of advanced convolutional, recurrent, transformer‑based, diffusion‑based or other neural network architectures in a task‑specific manner; (iii) some experience in training, validation and evaluation of deep neural network models on large datasets, evidenced by experience in using Python libraries like HDF5 or similar.

Desired qualifications:

• Publications, e.g. in top‑tier conferences and journals: IEEE Transactions on Image Processing, IEEE Transactions on Circuits and Systems for Video Technology, conferences like IEEE CVPR/ICCV/ECCV, NeurIPS, ICML, ICLR, or similar.
• Some theoretical understanding of the graphics pipeline, including coordinate transformations between frames of reference, PBR materials, rasterization, lighting, and ray tracing.
• Experience in image processing theory and methods, evidenced by the development of practical designs in this area.
• Some experience with 3D engines such as Unreal or Unity; in particular, generation of datasets, extraction of G‑buffers, motion vectors, etc.

Benefits:

• Discretionary bonus opportunity.
• Hybrid Working (within Flexmodes).
• Private Medical Insurance.
