2. Generative & Agentic AI Integration
- Build solutions leveraging models such as OpenAI, Azure OpenAI, Anthropic, or open-source LLMs.
- Design and implement agentic systems orchestrating multiple tools, actions, or reasoning steps.
- Develop RAG pipelines (indexing, vectorization, retrieval) and advanced contextualization mechanisms.
- Implement guardrails, robust prompting, security policies, and quality control mechanisms.
3. Engineering, Quality & Performance
- Produce maintainable, tested, high-performance code aligned with industry standards.
- Conduct technical code reviews, propose improvements, and solve complex engineering challenges.
- Diagnose, optimize, and monitor the performance of AI solutions in production.
- Contribute to DevOps/MLOps/GenAIOps practices: CI/CD, containerization, observability, continuous model evaluation.
4. Collaboration & Technical Leadership
- Work closely with architects, analysts, and business teams to understand use cases.
- Contribute to technical workshops, demos, and proofs of concept.
- Provide advanced technical support to development teams integrating AI.
- Document solutions, patterns, and recommended practices.
5. Innovation & Technology Watch
- Stay up to date with advancements in generative AI, agentic architectures, RAG, and orchestration frameworks.
- Experiment with new models, tools, and techniques to assess enterprise applicability.
- Identify optimization and innovation opportunities within the application ecosystem.
