Key Responsibilities:

• Architect and develop backend (Python/Django 4.x, Django REST Framework) and frontend (React) code for the 2-K admissions module in accordance with NYCPS standards and secure coding practices.
• Design and implement new Django models, serializers, and REST API endpoints for 2-K-admission and waitlist instances, DOB eligibility configuration, application checklists, and program directory-extending 3-K patterns while isolating 2-K logic to minimize regression risk.
• Implement 2-K eligibility and offer logic including age-based eligibility, FDOS vs. calendar-year cutoffs for NYCEEC/FCC seat types, provisional offer letter designation, DOB-based start date calculations, and configurable cutoff dates editable by NYCPS administrators without code changes.
• Extend the React application to support the 2-K program directory, search filters, simplified program cards, application submission, and eligibility messaging distinguishing NYCEEC-eligible from FCC-only-eligible students.
• Adapt the Gale-Shapley matching algorithm and offer pipeline to incorporate 2-K rules including FCC eligibility windows, provisional vs. standard letter selection, DOB-based merge fields, and automatic exclusion from non-2 K letter runs.
• Implement 2-K waitlist logic with differentiated auto-add rules based on FDOS eligibility, FCC-specific behavior, and age-based no-offer messaging-ensuring no disruption to existing waitlist processing.
• Write PostgreSQL queries, migrations, and schema definitions for 2-K data models, working with the database administration team. Implement Celery-based async task processing for bulk operations including letter generation, eligibility calculations, and waitlist processing.
• Write unit tests, integration tests, and automated regression tests for all 2-K logic, validating that changes to shared platform components do not introduce regressions across existing 3-K, Pre-K, or K-12 enrollment workflows.
• Validate system behavior under load during peak enrollment periods and ensure accessibility compliance (WCAG 2.1 AA) across all 2-K family-facing features.
