• Mentor colleagues for growth and success.

Mandatory Requirements

• Academic Qualification: Bachelor s degree with STEM background (Science, Technology, Engineering and Management) with strong quantitative flavour.

• Strong Fundamentals: The candidate is required to build quantitative models from first principles and hence need to have excellent understanding of basics in mathematics and statistics (e.g., differential equations, linear algebra, matrix, combinatorics, probability, Bayesian statistics, eigen vectors, Markov models, Fourier analysis).

• Core Expertise: The candidate is expected to specialize in Speech and Audio Signal Processing. Solid understanding of Automated Speech Recognition, Acoustic Model and Language Model is a pre-requisite. Excellent understanding of Spectral Analysis, Cepstral Analysis, Dynamic Time Warping, Hidden Markov Models is required. It is good to have hands-on model implementation skills for any one of the above areas using any widely used technology stack (e.g., Kaldi/C++, Mozilla-DeepSpeech, Facebook-Wave2Vec, Python/Tensor Flow/OpenCV/Keras)

• Emerging Trends - Artificial Intelligence and Machine Learning: Good Understanding of working principles of neural networks and underlying algorithms (e.g., convolutional-CNN), recurrent-RNN-LSTM-GRU, back-propagation, loss function, gradient descent)

• Data Wrangling and Model Lifecycle Maintenance: Experience in data cleaning, ETL, pipeline building and model-maintenance, using commonly used methodology (e.g., Airflow, MLflow)

• Communication : Ability to articulate key messages concisely and precisely

• Collaboration: Excellent interpersonal and teaming skills

Additional Preference

• Advanced Qualification: PhD in any Quantitative Discipline

• Eminence: Patents, publications, thought leadership, invited speakership and conspicuous presence in refereed platforms or forums of repute.
