Position: Senior Software Engineer 1 Backend (Python)

Role Summary

Owns the core API’s: the largest and most business-critical Python services covering students, users, authentication, organizations, the API gateway, and reporting, plus the central database migrations repository and the legacy LMS_Back monolith. These services run Flask with SQLAlchemy and Alembic, Redis/RQ background jobs, boto3/AWS integrations, and DocuSign e-signature workflows, deployed as Docker containers on EKS.

Key Responsibilities
Deliver features across the Python microservices and the reporting stack.
Maintain and harden the authentication service and API gateway (JWT issuance, routing, service-to-service auth).
Own the DocuSign e-signature integration embedded in flows.
Lead the Flask 1.x 2.x/3.x and dependency-CVE remediation program across owned services, coordinated with the Architect's upgrade policy.
Manage schema evolution through database_migrations (Alembic)



across MySQL and PostgreSQL.
Raise the testing bar: most owned services ship without test suites — introduce pytest coverage and CI gates.
Operate Redis/RQ background job workloads (croniter scheduling, async processing).
Participate in cross-review of the other Python services to reduce bus factor (CODEOWNERS).

Required Qualifications
7+ years backend engineering, 5+ in Python.
Expert Flask (or FastAPI with robust Flask willingness), SQLAlchemy 1.x2.x, Alembic.
MySQL and PostgreSQL: query tuning, schema design, protected migrations.
Redis-backed job queues (RQ, Celery, or equivalent).
AWS SDK (boto3): S3, SES/SNS, and service integration patterns.
pytest and test-infrastructure buildout in low-coverage codebases.
Docker; comfortable deploying to Kubernetes.
