Sr. Data Scientist

Transact Campus is transforming the student experience through credential-driven privileges, innovative commerce solutions and payments. Our enterprise-class cloud platforms power campus life for millions of students and institutions.

Join as a founding member of our new Predictive Analytics team, where you'll work with Product teams to define our ML/AI development strategy and build our machine learning infrastructure from the ground up. This is a hands‑on, high‑autonomy role — you'll take full ownership of the model lifecycle, from data exploration through to deployment and monitoring in production, working directly on our Databricks on Azure architecture.

You'll solve real-world commerce and privileges problems — including order wait time prediction, market basket analysis, and conversational AI — while establishing the engineering standards and architectural decisions that will define how we build ML capabilities going forward. Your work will have direct, visible impact on our product and on the student experience for millions of users.

  AI and chatbot capabilities, leveraging LLMs and retrieval‑augmented generation (RAG) pipelines
  
• Collaborate with the Data Analytics team to leverage existing Power BI and Databricks data
  infrastructure, and extend it with predictive capabilities
  
• Define and implement MLOps best practices, CI/CD pipelines for models, and data governance
  standards — establishing the foundations the team will scale on
  
• Ensure data quality, security compliance, and model reliability in production
  
• Provide technical leadership and mentor AI/ML team members across Data Analytics and
  Predictive Analytics teams
  
• Partner with cross‑functional teams to find data‑driven opportunities and translate them into
  shipped ML features
  
• Ensure data quality, governance, and model reliability in production
  
• Stay updated on emerging technologies in AI, ML, and data science to drive innovation
  
• Provide technical leadership and help set the standard for ML engineering rigour as the team

• Deep, hands‑on experience with Azure ML and MLflow for experiment tracking, model registry,
  and model serving
  
• Strong proficiency in Python and SQL for data manipulation and analysis
  
• Proven experience deploying and monitoring ML models in production independently, without
  dedicated MLOps support
  
• Experience with ML frameworks - scikit‑learn, MLFlow, TensorFlow, PyTorch, and Pandas
  
• Experience with big data platforms (Databricks, Apache Spark) and cloud services (Azure
  Lakehouse, AWS, or GCP).
  
• Solid knowledge of ML Ops principles - CI/CD for ML, model versioning, drift monitoring, and
  pipeline automation
  
• Exposure to data visualisation tools (Power BI, Tableau, Looker).
  
• Strong knowledge of statistical modelling and the ability to select and justify appropriate
  approaches for real‑world problems
  
• Strong communication skills - ability to present complex technical concepts clearly to non-
  technical stakeholders and influence product decisions with data
  

Strong Advantage:

• 
  
• Master’s in Data Science, Computer Science or a related field
  
• Hands‑on experience with LLM frameworks such as LangChain, LlamaIndex, or similar, and
  familiarity with RAG pipeline design
