The Developer II has responsibilities across the full Software Development Life Cycle (SDLC) from business requirements to support, but he or she is primarily focused on development activities. Development activities include: working with business analysts and customers to understand requirements; working with team members to apply secure programming techniques using standards and best practices; commenting code for peers and testers; performing unit testing, configuration management, source code control, deployment and release management; and providing support services as needed. Operational support services vary in scope from minor bug fixes (tickets) to major enhancements (change orders). As an application reaches the sunset stage, the developer is also expected to participate in planning efforts around replacement and modernization. The Developer II operates at the application level.
