Two (2) years of specialized experience may substitute for one (1) year of the academic requirement. Minimum Experience: Five (5) to eight (8) years of full-stack application development experience, including at least two (2) years of experience in legacy modernization or platform migration, along with demonstrated production use of AI-assisted development tools. Certifications: One required certification and one certification obtainable after hire. Preferred certifications include Oracle Certified Professional Java SE, Microsoft Certified: Azure Developer Associate, AWS Certified Developer - Associate, AWS Certified Machine Learning - Specialty, Microsoft Certified: Azure AI Engineer Associate, or GitHub Copilot or equivalent AI-assisted development credentials. Required Skills: Java and Spring Boot, React and TypeScript, RESTful API design, relational data modeling, legacy code analysis, AI-assisted development tools such as GitHub Copilot or Amazon Q Developer, prompt engineering for code translation and test generation, secure coding, and DevSecOps practices. Preferred Skills: Experience with Delphi, Pascal, or comparable 4GL technologies; retrieval-augmented generation (RAG) over legacy codebases and documentation; large language model evaluation and output validation; strangler-fig and parallel-run migration patterns; and federal-sector experience. Technical Environment: Java 17+ with Spring Boot, React 18 with TypeScript, REST and GraphQL APIs, PostgreSQL, SQL Server or Oracle databases, Docker, Kubernetes, AWS or Azure, GitHub Copilot or Amazon Q Developer, LangChain, retrieval-augmented generation, vector stores such as pgvector and OpenSearch, CI/CD tools including Jenkins, GitHub Actions or Azure DevOps, testing frameworks such as JUnit, Jest and Playwright, SonarQube, and legacy Delphi and Pascal source analysis tools. ## Description * Lead decomposition and reverse-engineering of legacy Delphi modules, using AI-assisted code analysis to recover undocumented business rules and data flows. * Architect and build target-state services in Java (Spring Boot) and front-end components in React, preserving functional parity with the legacy system. * Define and enforce the team's AI-assisted development standards, including prompt patterns, human review gates, licensing and provenance checks, and prohibited uses. * Build automated equivalence and regression harnesses, using AI-generated test scaffolding validated against legacy behavior. * Integrate AI coding assistants into the CI/CD pipeline with secrets hygiene and data-handling controls appropriate to sensitive case data. * Review all AI-generated code for correctness, security, and maintainability before merge; no AI output reaches production unreviewed. Mentor mid-level developers on both the target stack and disciplined AI-assisted engineering practice
