Responsibilities

Lowering deep learning graphs - from common frameworks (PyTorch, Tensorflow, Keras, etc) down to an IR for training and inference - with particular focus on ensuring reproducibility

Writing novel algorithms - for transforming intermediate representations of compute graphs between different operator representations

Owning two of the following compiler areas:

Front-end - deal with the handshaking of common Deep Learning Frameworks with Gensyn's IR for internal IR usage. Write Transformation passes in ONNX to alter IR for middle-end consumption

Middle-end - write compiler passes for training-based compute graphs, integrate reproducible Deep Learning kernels into the code generation stage, and debug compilation passes and transformations as you go

Back-end : lower IR from middle-end to GPU target machine code
