Your contributions will directly impact the sophistication and empathy of Sesame AI's platforms, pushing the boundaries of what's possible in AI communication.
Key Responsibilities
- Design and implement machine learning models for natural language understanding (NLU) and natural language generation (NLG) with an emotional intelligence focus.
- Analyze complex conversational data to identify patterns, sentiment, and emotional cues, informing model improvements.
- Develop and evaluate metrics for assessing emotional accuracy and conversational flow in AI interactions.
- Collaborate with engineering and product teams to integrate AI models into production systems.
- Research and apply state-of-the-art techniques in NLP, deep learning, and affective computing.
Required Skills
Strong proficiency in Python and relevant libraries (TensorFlow, PyTorch, scikit-learn, NLTK, SpaCy). Deep understanding of machine learning algorithms, especially deep learning architectures (transformers, RNNs, CNNs). Expertise in natural language processing, including text classification, sentiment analysis, and entity recognition. Solid statistical modeling skills and experience with A/B testing. Experience with cloud platforms (AWS, GCP, Azure) and big data technologies (Spark, Hadoop) is a plus. Excellent communication and collaboration skills are essential.
Interview Process
The interview process for a Data Scientist at Sesame AI typically involves 4-5 rounds. It usually starts with an initial recruiter screen, followed by a technical phone screen focusing on Python coding and basic ML concepts. Subsequent rounds include a take-home assignment or live coding session, an onsite (or virtual) interview loop with hiring managers and team members covering behavioral questions, machine learning theory, NLP expertise, and system design. Expect discussions around past projects and problem-solving scenarios related to conversational AI and emotional intelligence.
