Assist in designing software solutions and evaluate design trade-offs against business requirements.
Help convert high-level designs into detailed software designs using mock screens, pseudocode, and functional logic.
Select appropriate frameworks, platforms, and environments for coding, configuration, and scripting.
Help implement telemetry features by determining data and metric requirements.
Support ad hoc software code reviews to ensure baseline mitigations for known risks.
Create and configure code for products or systems to meet business and non-functional requirements, including maintainability, availability, and scalability needs.
Arrange software engineering requirements into a programming sequence.
Drive the creation of scripts to automate repetitive tasks in CI/CD, testing, and other processes.
Translate customer requirements into test strategies; select and implement testing tools; and identify testing scope and methods.
Ensure test cases cover all scenarios in software requirements and help execute tests to detect code errors and defects.
Participate in engineering projects by providing documentation, direction, and examples; identifying solutions and timelines; reviewing requirements; and translating them into technical solutions.
Support development, unit and regression testing, and production go-live activities for projects.
