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

There are opportunities for server-side business logic implementation as well as client web application and user interface (UI) development. Technologies include Java, Python, embedded C/C++, Java cryptographic framework, XML, web UI (Angular, JavaScript, CSS, HTML), and special purpose device programming opportunities.

The Software Engineer will be responsible for software development activities both individually and as a member of an Agile team. The Software Engineer will actively participate in daily stand-ups, Sprint Planning, Program Increment (PI) Planning, and other related team activities. The individual will analyze and study complex system requirements, use design software tools, provide support using formal specifications, data flow diagrams, and other accepted design techniques.

They will use sound software engineering principles to ensure that developed code is modifiable, efficient, reliable, understandable, fault tolerant, and reusable. They will provide software process management and control throughout the coding portion of the software development process and promote code reuse and cross-program collaboration while reducing maintenance costs by creating common functions and shared actions for developers and testers.

They will engineer, author, tune and document automation scripts in a development environment and deploy to the test/production bench.
