Data Scientist

What you will do

The Data Scientist will play a pivotal role in planning, executing and delivering machine learning-based projects. The bulk of the work will be in machine learning (ML) modelling, management and problem analysis, data exploration and preparation, data collection and integration, operationalization.

The Data Scientist will be a key interface between the analytics team and the business(s) and various other departments (such as IT). Candidates need to be very much self-driven, curious and creative.

How you will do it

• Problem Analysis and Project Management
  • Guide and inspire the organization about the business potential and strategy of artificial intelligence
  • Identify data-driven/ML business opportunities
  • Collaborate across the business to understand IT and business constraints
  • Prioritize, scope, and manage data science projects and the corresponding key performance indicators (KPIs) for success
  • Define and communicate governance principles

• Data Collection and Integration
  • Understand new data sources and process pipelines and catalog/document them
  • Acquire access to various databases and other sources systems such as SQL or graph databases
  • Create data pipelines for more efficient and repeatable data science projects

• Data Exploration and Preparation
  • Apply statistical analysis and visualization techniques to various data, such as hierarchical clustering, T-distributed Stochastic Neighbor Embedding (t-SNE), principal components analysis (PCA) Machine Learning
  • Generate hypotheses about the underlying mechanics of the business process
  • Test hypotheses using various quantitative methods
  • Display drive and curiosity to understand the business process to its core
  • Network with domain experts to better understand the business mechanics that generated the data

• Machine Learning
  • Apply various ML and advanced analytics techniques to perform classification or prediction tasks
  • Integrate domain knowledge into the ML solution; for example, from an understanding of financial risk, customer journey, quality prediction, sales, marketing
  • Testing of ML models, such as cross-validation, A/B testing, bias and fairness

• Operationalization
  • Collaborate with ML operations (MLOps), data engineers, and IT to evaluate and implement ML deployment options
  • integrate model performance management tools into the current business infrastructure
  • Implement champion/challenger test (A/B tests) on production systems
  • Continuously monitor execution and health of production ML models
  • Establish best practices around ML production infrastructure

• Other
  • Train other business and IT staff on basic data science principles and techniques
  • Train peers on specialist data science topics
  • Network with internal and external partners
  • Upskill yourself (through conferences, publications, courses, local academia and meetups).
  • Promote collaboration with other data science teams within the organization (if there is a decentralized data science practice). Encourage reuse of artifacts
