• Design end-to-end IT architectures for AI solutions selecting appropriate models components and techniques.
• Apply modern AI approaches and enterprise IT architecture practices (scalability security observability).
• Present solution blueprints to technical and business audiences moderate discussions and collect feedback.
• Data MDM and MLOps
• Support best practices for data quality master/metadata management lineage and governance.
• Implement modern MLOps: model/version registries CI/CD for ML feature stores monitoring retraining pipelines.
• Delivery & Integration
• Independently develop test document and integrate AI/ML components into service-oriented architectures.
• Ensure production readiness: reliability resilience performance security and compliance.
• Collaboration & Communication
• Work closely with cross-functional teams (data engineers architects product owners).
• Translate business needs into AI capabilities and measurable outcomes.

Specific Expertise (Required)

• Programming & AI Stack
• Excellent Python skills and core AI/ML/NLP libraries: pandas scikit-learn PyTorch TensorFlow Transformers spaCy NLTK; experience with OpenAI APIs/SDKs.
• Advanced AI Techniques
• Proven experience with LLMs and generative AI (prompting fine-tuning adapters/LoRA retrieval augmentation).
• ML algorithms and NLP pipelines in production contexts.
• Data & Platforms
• Modern data engineering practices: ETL/ELT pipelines streaming/batch metadata/model versioning.
• Database integration: SQL (e.g. Postgres) and NoSQL (e.g. Elasticsearch MongoDB Cassandra).
• Cloud & Operations
• Hands-on deployment on AWS and/or Azure (compute storage security networking managed ML services).
• Software engineering and DevOps: Git workflows CI/CD containerization (Docker) orchestration (Kubernetes) observability.
• Architecture & Integration
• Experience integrating AI components within service-oriented and event-driven architectures.
• Ability to produce high-quality design docs diagrams and PoCs leading to scalable solutions.
• Ethics Risk and Compliance
• Awareness of ethical/legal implications of AI (bias privacy IP model/data governance) ideally in enterprise or public sector environments.

Desirable Expertise (Assets)

• Experience with vector databases (e.g. FAISS pgvector Milvus) feature stores model registries.
• Knowledge of security for AI systems: data anonymization secret management network policies policy-based access.
• Experience with evaluation frameworks (e.g. RAGAS prompt eval) guardrails content filtering red-teaming.
• Familiarity with infrastructure-as-code (Terraform) workflow orchestration (Airflow Argo) and serverless.
• Prior work with enterprise architecture tools (e.g. Sparx Enterprise Architect).

Language

• Fluent in English (spoken and written).
• All documentation will be produced in English.

Tools & Methodologies

• Tools: MS Teams IntelliJ JIRA Enterprise Architect GitHub/GitLab Docker Kubernetes model registries.
• Methodologies/Frameworks: Agile
