• Communicate effectively with both technical and non-technical stakeholders, translating complex technical concepts into clear, actionable information while building strong working relationships across Government, engineering, and mission teams.
• Balance competing priorities and changing mission needs while maintaining a strong focus on system reliability, security, performance, and successful delivery of customer outcomes.
• Apply a strong application design mindset throughout the development lifecycle, helping teams thoughtfully evaluate solution approaches, architecture, interfaces, dependencies, scalability, security, and maintainability before significant development begins.
• Demonstrate proficiency with Confluence, Jira, and Jira Advanced Roadmaps to support requirements management, technical documentation, backlog development, dependency tracking, and cross-team planning and delivery.
• Experience working in AWS environments; familiarity with cloud-based application architectures, services, integrations, and deployment considerations is preferred.
