The ideal candidate is a seasoned full-stack engineer who thrives at the intersection of legacy system modernization and modern AI-assisted development.

? Act as a subject matter expert and escalation point for complex engineering challenges across the portfolio
Application Development & Modernization:
? Design, develop, and maintain features across .NET/C#, Java, and React-based applications in both web and mobile contexts
? Drive the modernization of legacy systems - refactoring aging codebases, improving performance, and introducing contemporary patterns (REST APIs, microservices, component-based front ends) using AI-assisted development workflows
? Build and maintain RESTful APIs and integrate with internal data systems, third-party services, and city agency platforms
? Ensure all applications meet security, accessibility (WCAG), and compliance standards appropriate for a public-sector environment
? Contribute to mobile development efforts supporting the iOS and Android applications.
AI Tooling & Developer Productivity:
? Champion the adoption of AI-assisted development tools (e.g., GitHub Copilot, Cursor, Claude Code, or similar) to increase team velocity and reduce technical debt remediation timelines
? Develop and refine internal AI-augmented workflows for code generation, automated testing, documentation, and legacy code analysis
? Evaluate and implement LLM-based capabilities where appropriate within applications (e.g., intelligent search, automated summarization, chatbot interfaces for resident-facing features)
? Stay current on AI/ML tooling trends and serve as an internal resource for the team on responsible and effective AI usage in software development
Mentorship & Team Development:
? Mentor mid-level and junior engineers through code reviews, pairing sessions, design discussions, and direct feedback
? Foster a collaborative team culture that values craft, continuous learning, and inclusive problem-solving.
