• Set the multi-year technical roadmap for the application portfolio; lead build-versus-buy evaluations and present recommendations to Digital & IT leadership.
• Embed security and performance requirements into design: threat modeling, secure coding practices, and load and scalability testing.
• Implement and enforce UI/UX standards; ensure consistent, accessible user experiences across all applications.
• Partner with AI & Automation Engineer to introduce AI-assisted development practices (GitHub Copilot, AI code review).
• Set the standard for AI-leveraged engineering: redesign development workflows around AI tooling, measure the resulting productivity gains, and coach the team toward the same level of output.

Legacy Modernization:

• Assess technical debt in legacy systems; define incremental refactoring and migration paths.
• Lead legacy system modernization sprints, ensuring backward compatibility and stakeholder communication.
• Own the modernization business case: sequencing, effort and cost estimates, and risk trade-offs presented to business stakeholders.

Quality & Testing:

• Define and track automated testing coverage; champion test-driven development.

Master’s degree in a related field preferred., * Minimum of 7 years of full-stack software engineering experience in production environments, including at least 2 years in a senior or technical lead capacity.
• Demonstrated experience owning end-to-end architecture for multiple production applications, and mentoring both junior and mid-level engineers.
• Demonstrated track record of using AI tools to multiply engineering output - candidates should be able to point to work where AI-assisted development delivered order-of-magnitude (up to 20x) gains in throughput or cycle time, and explain how those gains were measured.

Technical Skills:

• Front-end: JavaScript/TypeScript, React, Angular, or Vue; HTML5, CSS3.
• Back-end: C#/.NET Core, Node.js, or Python.
• Database: SQL Server, Azure SQL, or equivalent; understanding of ORMs and query optimization.
• Azure application services: App Service, Azure Functions, Container Apps, API Management.
