Standards: Apply software engineering best practices including OOP, unit testing, and CI/CD.
To be successful in this role, you must demonstrate specific experience in:
Large Dataset Management: A track record of handling GB-scale data (4GB+) and addressing performance via vectorisation, parallelism, or memory optimisation.
Advanced Python Logic: Writing modular, production-quality code using classes/functions and addressing bottlenecks via chunking or asynchronous processing.
Analytical Pipelines: Building end-to-end pipelines that handle data ingestion, transformation, and modelling.
C# literacy: Ability to read and understand C# - not necessary to write, but understanding of cohesion between Python & C# is desirable.
