Key Responsibilities
- Design,
build and maintain Python plugins that encapsulate business rules and
transformation logic such as custom aggregation/disaggregation, rule-based
data enrichment, and time-grain manipulations.
- Implement
data-cleaning, validation, mapping and merging routines using Pandas,
NumPy and other Python libraries to prepare inputs for downstream
analytics.
- Define
clear interfaces and configuration schemes for plugins (for example,
picklists for output grains and rule codes) and package them for easy
consumption by implementation teams.
- Profile
and optimize Python code paths—leveraging vectorized operations, efficient
merges and in-memory transformations—to handle large datasets with low
latency.
- Establish
and enforce coding standards, write comprehensive unit and integration
tests with pytest (or similar), and ensure high coverage for all recent
components.
- Triage
and resolve issues in legacy scripts, refactor complex routines for
readability and extensibility, and manage versioning across releases.

Collaborate with data




engineers and analysts to capture requirements, document plugin behaviors,
configuration parameters, and usage examples in code repositories or internal
wikis.

Requirements
Must-Have Skills
- 5–7
years of hands-on experience writing well-structured Python code, with
deep familiarity in both object-oriented and functional programming
paradigms.
- Expert
mastery of Pandas and NumPy for transformations (group-by aggregations,
merges, column operations), plus strong comfort with Python’s datetime and
copy modules.
- Proven
experience designing modular Python packages, exposing configuration
through parameters or picklists, and managing versioned releases.
- Ability
to translate complex, rule-driven requirements (such as disaggregation
rules, external-table merges, and priority ranking) into clean Python
functions and classes.
- Proficiency
with pytest (or equivalent), mocking, and integrating with CI pipelines
