You will perform software development lifecycle (SDLC) activities as both an individual and a member of our top-notch agile development team building a large complex enterprise system. Development includes the full range of turning Agile user stories into implementable concepts, through development, unit testing, integration and test, and deployment of the new capabilities for the large complex enterprise system. Following the Behavior-driven Development (BDD) pattern, developers are responsible for implementing robust testing leveraging DevOps automation and, where appropriate, use of test automation commercial tools.

You will provide software process management and control throughout the coding portion of the software development process and will promote code reuse and cross-program collaboration while reducing maintenance costs by creating common functions and shared actions for developers and testers. You will engineer, author, tune and document automation scripts in a development environment and deploy to the test/production bench.
