**Job Responsibilities

Build and maintain mathematical optimization models — objective functions,
constraints, and penalty calibration

Encode and validate business rules, contract parameters, and operational
constraints into model inputs

Execute regression testing and model health checks before and after every
production run

Conduct scenario and sensitivity analysis with documented trade-offs and
business recommendations

Validate all input files pre-run — NULL checks, format errors, anomalies, and
data readiness sign-off

Monitor data pipeline health, audit logs, and ingestion failures across
recurring run cycles

Perform data quality assessments — missingness, outliers, duplicate records,
and consistency checks

Validate model outputs and savings calculations — ensuring mathematical
accuracy and business defensibility

Review compliance and performance tracking — compare actuals vs recommendations
and document deviations

Review output files for anomalies and formatting issues before stakeholder
delivery

Support recurring run preparation — scenario setup, input file review, and run
orchestration

Partner with business stakeholders to explain model outputs and recommendations
in plain language

Mentor junior team members on best practices, coding standards, and
documentation discipline
