Job summary: As a Senior Data Scientist for Messaging App, you will play a critical role in developing and deploying machine learning models to enhance the security, productivity, and intelligence of our messaging platform. You will work on a variety of challenging problems, from detecting and preventing fraud and abuse to building intelligent agent solutions that assist users within the chat environment. You will have a strong background in classical machine learning techniques, natural language processing (NLP), and experience with both large language models (LLMs) and small language models (SLMs). You will work closely with product managers, engineers, and other data scientists to deliver impactful data- driven solutions. Key Responsibilities: Model Development & Deployment:
Design, develop, train, evaluate, and deploy machine learning models for a variety of applications within KChat, including: ■ Security: ● Fraud detection and prevention (e.g., identifying phishing scams, spam, malicious links). ● Abuse detection (e.g., identifying hate speech, harassment, and other policy violations). ● Account takeover detection. ● Anomaly detection. ■ Productivity: ● Smart reply suggestions. ● Message summarization. ● Task automation (e.g., scheduling meetings, setting reminders). ● Content recommendations. ● Translation.
■ Agent AI:
● Fine- tuning and customizing LLMs and SLMs for specific tasks and domains. ● Building and integrating intelligent agent solutions (chatbots) within KChat to assist users with various tasks. ● Developing natural language understanding (NLU) and dialogue management capabilities for agents.
Implement data preprocessing, feature engineering, and model selection techniques. Deploy models to production and monitor their performance. Use a variety of machine learning algorithms, including classical ML models (e.g., logistic regression, SVM, random forests), deep learning models (e.g., transformers, LSTMs), and language models (LLMs and SLMs). Work with large datasets of text, user activity, and other relevant data.
Data Analysis & Insights
Communicate findings and recommendations to product and engineering teams. Analyze user behavior and messaging data to identify opportunities for improvement.
Collaboration:
Work with other data scientists to share knowledge and best practices. Work closely with product managers to define product requirements and translate them into data science solutions. Collaborate with engineers to integrate models into the KChat platform.
Research & Innovation:
Explore and evaluate new techniques and technologies. Stay up- to- date on the latest data science and machine learning research.
