Contribute to frontend development, including React component design and API integration. Implement and support Command Query Responsibility Segregation (CQRS) patterns where appropriate. Use AI-assisted coding tools, including Copilot CLI, Claude Code, and Codex, to accelerate feature delivery, refactor code, improve tests, and support documentation. Develop and manage agent-driven coding workflows, coordinating multiple AI agents to build, test, and iterate on features in parallel. Refine code through iterative AI feedback loops, including prompting, validation, and continuous improvement. Review and audit AI-generated code to ensure accuracy, security, maintainability, and compliance with engineering standards. Establish guardrails, validation patterns, and review processes that promote the safe and reliable use of AI-generated output. Manage multiple parallel workstreams effectively, maintaining clarity around feature ownership, dependencies, and deliverables. Collaborate with Product, QA, and engineering colleagues to deliver high-quality software aligned with business objectives. Participate in code reviews and contribute to engineering standards, technical practices, and continuous improvement. Embed security, compliance, and quality considerations throughout the application stack. Support and mentor other engineers through pairing, constructive feedback, and knowledge sharing.
