Position Summary

We are seeking a senior full-stack developer to own and modernize shared Python/Django capabilities and serve as the technical escalation point for complex, cross-application work. The role combines hands-on development with architecture, secure identity and database integration, lifecycle upgrades, production troubleshooting, documentation, and mentoring. The developer will collaborate with application teams, DevTools/DevOps, NIH CIT, Security, and database administrators across on-premises and AWS environments.

Key Responsibilities

  • Application engineering. Design, develop, test, and maintain Python/Django applications, reusable libraries, REST APIs, and supporting JavaScript/HTML/CSS components.
  • Python and Django lifecycle upgrades. Lead end-of-life upgrades across the application portfolio: inventory dependencies, assess compatibility, update requirements and internal packages, refactor deprecated APIs, test across environments, coordinate consuming teams, and publish migration and rollback guidance.
  • Runtime and package engineering. Build, validate, package, and distribute Python runtimes from source when approved installers are unavailable; verify checksums, test suites, pip/virtual-environment behavior, and compatibility with internal artifact repositories.
  • Shared Django platform ownership. Modernize shared Django infrastructure libraries and related packages; deliver Python 3.12+ compatibility, automated tests, versioning, deprecation paths, architecture diagrams, runbooks, and coordinated adoption by dependent applications.
  • PIV, SSO, authentication, and authorization. Implement and troubleshoot NIH Login/SiteMinder, CAS and django-cas-ng, AWS Cognito, JWT/OAuth2, Django authentication backends, authorization decorators, role and permission mapping, and secure session handling.
  • Secure database integration. Connect Django applications to Oracle, PostgreSQL, AWS RDS, and other approved data sources through centralized password-lookup and secrets-management services; support credential rotation, least privilege, and removal of hard-coded secrets.
  • Application security. Enforce Content Security Policy (CSP), XSS/CSRF protections, HSTS, secure headers and cookies, dependency remediation, and penetration-test findings; favor external scripts or nonce/hash-based CS

Preferred Qualifications:

  • Experience with git and the Gitflow workflow.
  • Experience reading SQL.
  • Experience using RDMS.
  • Experience with continuous integration/continuous deployment environment.
  • Experience with automated testing.
  • JavaScript development beyond jQuery.
  • Experience using the basic components of the AWS environment (EC2, Bastion, RDS, S3)

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way.
