You will actively participate in daily stand‑ups, Sprint Planning, Program Increment (PI) Planning, and other related team activities; analyze and study complex system requirements, use design software tools, provide support using formal specifications, data flow diagrams, and other accepted design techniques and will use sound software engineering principles to ensure that developed code is modifiable, efficient, reliable, understandable, fault‑tolerant, and reusable. 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.
