• Build and manage RAG pipelines, including ingestion, preprocessing, chunking, embeddings, indexing, retrieval, and evaluation.
• Architect and implement agentic AI systems, including multi-step reasoning, tool usage, orchestration, and multi-agent patterns.
• Establish prompt evaluation frameworks, benchmarking processes, and continuous improvement loops for quality, latency, and cost.
• Apply fine-tuning and domain adaptation techniques where necessary.
• Ensure responsible AI practices, including governance, safety, and reliability in production environments.

2. Software Engineering & Full Stack Development

• Design and build scalable backend systems using Python (FastAPI or similar) and/or Java-based architectures.
• Develop modern front-end applications using React, Angular, or Vue frameworks.
• Build and maintain APIs, microservices, and integrations across internal and external systems.
• Ensure system performance, scalability, observability, and reliability across the stack.
• Contribute to architectural decisions and long-term technical roadmap development.

3. Data & AI Infrastructure

• Design and manage data pipelines (ETL) to support AI workflows and model performance.
• Implement and maintain vector databases and embedding-based retrieval systems.
• Deploy, monitor, and optimize AI models in production environments.
• Optimize inference performance, scalability, and cost efficiency.
• Leverage cloud platforms (AWS, GCP, Azure) and AI services such as Vertex AI.

4. Architecture & Technical Leadership

• Translate business requirements into scalable architectures, technical specifications, and delivery plans.
• Lead development efforts, including system design, code reviews, and engineering best practices.
• Mentor team members and promote a culture of engineering excellence and AI adoption.
• Collaborate cross-functionally with product, operations, and leadership teams to deliver impactful AI solutions.
• Evaluate emerging AI tools, frameworks, and technologies for practical implementation.

5. Quality, Testing & Deployment

• Develop and implement testing strategies across application and AI layers, including unit, integration, regression, and performance testing.
• Maintain CI/CD pipelines and ensure production readiness of all systems.
• Monitor system performance, manage incidents, and drive continuous optimization.
• Ensure high standards of reliability, scalability, and consistency across releases.

6. Compliance, Data Security & Governance (PHI, HIPAA, and AI Safety)

• Ensure all AI systems, data pipelines, and integrations comply with HIPAA and organizational data security standards.
• Implement safeguards for handling Protected Health Information (PHI), including encryption, access control, and secure transmission.
• Establish audit trails, monitoring systems, and governance frameworks for AI usage and data handling.
• Conduct risk assessments related to AI systems, data exposure, and model behavior.
• Collaborate with compliance and security teams to enforce best practices in data protection and AI governance.

Authority & Accountability

• Responsible for architecture, development, and performance of AI-powered systems across the organization.
• Authority to define and enforce engineering standards, AI practices, and system design decisions.
