We at WriteLab (writelab.com) are building ML tools to give immediate writing feedback for students and English language learners. There is plenty of room to impact the product by designing and implementing new features, usually starting with data collection. We use all the good stuff in deep learning and NLP including: SpaCy, scikit-learn, TensorFlow, etc.
Strong background in machine learning and experience deploying ML models in production is a must. NLP and DL experience is a strong plus.
