• Use Ansible for configuration management, environment provisioning, and repeatable deployments across Linux/Windows.
• Establish secure‑by‑design practices (authentication/authorization, secret management, data access controls) and enforce coding standards.
• Instrument applications and pipelines with monitoring and logging; drive performance tuning, memory management, and cost optimization.
• Apply GenAI techniques (prompt engineering, RAG, fine‑tuning) and deep learning methods to solve practical user and business problems.
• Build evaluation harnesses and guardrails for LLM quality, safety, hallucination reduction, and bias assessment; iterate based on telemetry.
• Collaborate with product, data, security, and platform teams to prioritize roadmaps and translate ambiguous problems into delivered capabilities.
• Create clear technical documentation, architecture diagrams, and runbooks; participate in design and code reviews.
• Appropriately assess risk when business decisions are made, demonstrating consideration for the firm's reputation and safeguarding Citigroup, its clients and assets, by driving compliance with applicable laws, rules and regulations, adhering to Policy, applying sound ethical judgment regarding personal behavior, conduct and business practices, and escalating, managing and reporting control issues with transparency.
