prompt-injection, data-leakage, model-bias, unsafe-output, and unauthorized-tool-use risks.- Measure AI solutions using defined quality, accuracy, safety, performance, adoption, and business-value metrics.- Maintain awareness of rapidly evolving AI models, development tools, frameworks, security risks, and engineering practices.Software Delivery and Testing- Own software delivery from initial discovery and architecture through development, testing, deployment, production support, and continuous improvement.- Write clean, modular, testable, secure, and well-documented production code.- Develop and maintain unit, integration, API, user-interface, regression, performance, security, and end-to-end automated tests.- Use AI-assisted testing and automation tools while independently validating generated code and test results.- Participate in peer reviews, design reviews, architecture reviews, threat modeling, and release-readiness assessments.- Build and maintain continuous integration and continuous delivery pipelines.- Release software through safe, incremental, observable, and reversible deployment practices.- Ensure that functional requirements and acceptance criteria are demonstrably satisfied before production release.Application Ownership and Operational Excellence- Serve as the accountable engineer or technical owner for up to three assigned applications.- Maintain a clear understanding of each application’s architecture, business purpose, users, integrations, data flows, dependencies, risks, and operational requirements.- Monitor application availability, performance, capacity, security, errors, and user experience.- Diagnose and resolve production incidents, defects, integration failures, and performance issues.- Perform routine maintenance, framework and dependency upgrades, operating-system or platform updates, certificate renewals, configuration changes, and technical-debt remediation.- Patch application and infrastructure vulnerabilities within established remediation timelines.- Maintain current application documentation, support procedures, runbooks, architecture diagrams, data-flow diagrams, deployment instructions, and recovery procedures.- Participate in incident response, root-cause analysis, corrective-action planning, disaster-recovery testing, and business-continuity exercises.- Recommend modernization, re-platforming, consolidation, or retirement when an application no longer meets business or technical standards.Security, Architecture, Data, and Support Collaboration- Work closely with the Information Security team to implement secure coding standards, identity and access controls, encryption, secrets management, vulnerability management, logging, monitoring, and regulatory controls.- Partner with Enterprise Architecture to ensure solutions align with approved technology standards, integration patterns, cloud strategies, and target-state architecture.- Collaborate with enterprise database and data-management teams on data models, storage patterns, data quality, lineage, retention, privacy, and performance.- Coordinate with IT Support and operations teams to ensure applications can be effectively monitored, supported, maintained, and recovered.- Work with infrastructure, cloud, network, identity, DevOps, quality-assurance, product, legal, risk, and compliance teams as required.- Clearly communicate technical decisions, constraints, risks, tradeoffs, progress, and recommendations to both technical and nontechnical audiences.Engineering Standards and Governance- Follow established software-development lifecycle, change-management, security, architecture, data-governance, and release-management standards.- Ensure applications comply with applicable legal, regulatory, privacy, records-management, accessibility, and industry requirements.- Maintain traceability between business requirements, technical designs, code changes, tests, approvals, and releases.- Protect confidential, proprietary, customer, and regulated data throughout the development and production lifecycle.- Ensure AI-generated code and content are reviewed, tested, licensed appropriately, and treated with the same rigor as human-created work.- Contribute reusable engineering patterns, libraries, templates, prompts, skills, development standards, and
