As an ML Engineer at Sesame AI, you will be at the forefront of developing and deploying cutting-edge machine learning models that power emotionally intelligent conversational AI. Your work will directly impact how users interact with AI, making these interactions more natural, empathetic, and effective. This role requires a deep understanding of natural language processing (NLP), emotional AI, and robust MLOps practices to bring research ideas into production systems that can handle real-world complexities and scale.

Key Responsibilities

• Design, develop, and implement advanced NLP and emotional intelligence models for conversational AI platforms.
• Optimize existing models for performance, scalability, and efficiency in production environments.
• Collaborate with research scientists and product managers to translate novel AI concepts into deployable features.
• Build and maintain robust data pipelines for training, evaluation, and monitoring of ML models.
• Conduct A/B testing and performance analysis to continuously improve model accuracy and user experience.

Required Skills

• Strong proficiency in Python and ML frameworks such as TensorFlow, PyTorch, or JAX.
• Extensive experience with NLP techniques, including transformers, large language models, and sentiment analysis.
• Solid understanding of machine learning algorithms, data structures, and software engineering principles.
• Experience with MLOps tools and practices (e.g., Docker, Kubernetes, AWS/GCP/Azure ML services).
• Familiarity with speech recognition, emotional AI, or multimodal AI is a significant plus.

Interview Process

The interview process for an ML Engineer at Sesame AI typically involves 4-5 rounds. It generally starts with an initial recruiter screen, followed by a technical phone screen focusing on coding and ML fundamentals. Subsequent rounds include a deep dive into machine learning theory and system design, a behavioral interview, and potentially a take-home assignment or an on-site (virtual) loop with multiple team members, including engineers, research scientists, and hiring managers. Expect questions on NLP, model deployment, and scaling challenges.

Salary & Compensation

The salary range for an ML Engineer at Sesame AI is typically between $160,000 and $250,000 annually, depending on experience, skill set, and performance during the interview process. This compensation package often includes a competitive base salary, stock options or restricted stock units (RSUs), and a comprehensive benefits package covering health, dental, vision, and retirement plans. Performance bonuses may also be part of the total compensation.
