Data Scientist II

Job Description

Join our dynamic team as a Data Scientist II and work at the forefront of data-driven innovation. You'll dive deep into exploratory data analysis, modeling, and MLOps to craft impactful solutions across multidisciplinary teams.

Duties and Responsibilities:

• Collaborate and work across functional and multidisciplinary teams in a dynamic environment to develop an understanding of evolving/agile business needs

• The Data Scientist role has work across the following four areas:

  • Exploratory data analysis:

    • Conduct in-depth exploratory data analysis (EDA) to uncover hidden patterns, anomalies, and trends.

    • Utilize statistical techniques and data visualization tools to communicate insights effectively to both technical and non-technical stakeholders.

    • Perform hypothesis testing and A/B testing to validate assumptions and measure the impact of data-driven decisions.

  • Feature engineering and enrichment: 

    • Create and refine relevant features from raw data to enhance model performance.

    • Leverage large language models (LLMs) to generate novel features and augment existing datasets.

  • Modeling:

    • Design, develop, and deploy advanced machine learning models (e.g., regression, classification, clustering) to address complex business problems.

    • Continuously improve model performance by fine-tuning hyperparameters, exploring new algorithms, and incorporating feature engineering techniques.

    • Collaborate with domain experts to understand business objectives and translate them into actionable data science solutions.

  • Data Operations and MLOps: 

    • Develop and maintain efficient data pipelines to extract, transform, and load (ETL) data from various sources.

    • Deploy and manage machine learning models in production environments using MLOps practices.

    • Monitor model performance, retrain as needed, and implement automated retraining pipelines.

    • Collaborate with software teams to ensure seamless integration of data science solutions into the broader technology stack.

Requirements and Qualifications:

• BS/MS in Science (Statistics, Computer Science, Econometrics, Data Science, Artificial Intelligence ).

• 1-5 years of experience with data science or computer science fields

• Experience with common data science toolkits, programming languages, visualization tools and SQL/NoSQL databases.

• Good applied statistical knowledge with emphasis in business and finance related statistical distributions, statistical testing, modeling, regression analysis, etc.

• Good foundation of computer science knowledge such as data structure, operating system

• Familiar or prone to adopt design thinking methods.

• Able to work under pressure and change, and balance among speed, reliability, interpretability.

• Experience with code versioning, code review and documentation.

• Effective communication skills

• Experience in building part-time projects which focuses on:
