• Identify ways to improve technology, processes, and performance.
• Identify opportunities to apply approved AI tools and AI-assisted engineering practices to improve development velocity, code maintainability, testing efficiency, and documentation quality.
• Participate in design, code, AI-assisted code validation, and technical design reviews.
• Build solutions that significantly impact company growth.
• Participate in an Agile scrum-based software development environment.
• Work closely with internal and external team members to decompose requirements, design software, and prioritize tasks.
• Collaborate with product, architecture, security, and engineering partners to evaluate AI-enabled application patterns, automation opportunities, and responsible AI considerations where appropriate.
• Meet periodically with onsite and offshore developers to review and improve code quality, requirements specifications, and design methodologies.
• Troubleshoot, debug, and improve existing integrations and software.
• Actively participate in team meetings to ensure team deliverables are met.
• Provide hands-on development, AI-assisted engineering guidance, and mentoring as necessary for other members of the development team.
• Create project artifacts such as technical specifications, AI usage notes, solution design documentation, and metrics reports.
• Identify technology risks early and establish mitigation plans.
• Apply AI-assisted development practices to improve engineering productivity, code quality, testing, documentation, and solution delivery.

Required Qualifications

• Solid background in application development; minimum 5 years of experience.
• Demonstrated ability to apply .Net development tools and techniques across coding, debugging, refactoring, test creation, documentation, and code review workflows.
