Senior Principal Application Software Engineer

Adheres to and optimizes execution of all phases of the application software development lifecycle; coaches engineers to drive application-focused improvements. Utilizes depth and breadth of expert knowledge to develop and guide new application features and enhancements, leading design specifications, ensuring accessibility, and maintaining documentation for application design and code. Leads process, architecture, and/or code reviews across a project and/or complete application/product/service to drive improvements. Conducts debugging and troubleshooting to identify and fix highly complex application issues. Develops fixes for identified issues. Troubleshoots and resolves highly complex issues related to application programming interface (API) functionality, integration, and service-to-service interactions. Designs and develops application software, systems, and services, reporting results to manager and/or senior technical leaders upon completion. Defines project or design scope for application components and services. Collaborates with stakeholders across business lines and drives efforts to understand customer use cases, root causes, and mitigations to align and explain rationale behind application solutions. Can provide advanced technical guidance and support to customers regarding application-related issues to mitigate recurrence. Collaborates with the team and cross-functionally to follow and suggest improvements to application development practices, secure coding standards, and code quality, providing coaching to less experienced team members. Utilizes innovation to perform periodic maintenance and testing operations for application systems that require upgrading or patching (e.g., for critical vulnerabilities).
