01

Understand the role

What matters most

  • Production-Grade AI Lifecycle Management

    The role requires moving beyond experimentation to managing the full lifecycle of LLM-based and agentic systems. You must prioritize establishing robust guardrails, human-in-the-loop workflows, and automated evaluation frameworks to ensure reliability in a high-stakes airport environment.

  • Enterprise AI Architecture and Standards

    You are expected to define the technical strategy for AI-native products, including build-versus-buy decisions. This involves architecting scalable solutions on AWS that integrate RAG, vector search, and agentic workflows while maintaining consistent engineering standards across the organization.

  • Cross-Functional Team and Vendor Leadership

    Success depends on managing a multidisciplinary team of in-house and offshore resources. You must balance technical mentorship with commercial responsibilities, such as budget management, vendor performance oversight, and translating complex business challenges into actionable delivery roadmaps.

Likely challenges to think through

  • Balancing Innovation with Operational Stability

    Airport operations are mission-critical, creating a tension between adopting cutting-edge generative AI and maintaining system reliability. Prepare to discuss how you implement observability, fallback mechanisms, and rigorous testing to mitigate the inherent unpredictability of LLMs in production.

  • Managing Distributed and Offshore Delivery

    Leading a team that includes offshore resources requires strong communication and delivery discipline. You may face challenges in maintaining code quality and architectural consistency; prepare to explain your approach to standardizing CI/CD, infrastructure as code, and collaborative development practices across different time zones.

  • Translating Technical Complexity for Stakeholders

    You must bridge the gap between technical AI capabilities and business outcomes for non-technical stakeholders. The challenge lies in justifying AI investments and managing expectations regarding performance, latency, and costs; prepare to demonstrate how you quantify business value and explain technical trade-offs to senior leadership.

03

Practice your answers

Technical practice

Designing Production-Grade RAG Systems

What to coverExplain how you would architect a Retrieval-Augmented Generation (RAG) pipeline for high-availability enterprise use. Focus on strategies for data ingestion, vector database selection, retrieval accuracy, and how you handle grounding to minimize hallucinations in a production environment.

Agentic Workflow Orchestration

What to coverDescribe your approach to designing agentic systems that utilize tool or function calling. Discuss how you manage state, error handling, and the trade-offs between autonomous agent behavior and deterministic system requirements.

AI Observability and Monitoring

What to coverHow do you establish observability for LLM-based applications beyond standard infrastructure metrics? Address how you track model performance, latency, token consumption costs, and drift in retrieval quality over time.

Enterprise AI Guardrails and Security

What to coverDetail the implementation of guardrails for generative AI in a corporate setting. Discuss techniques for input/output filtering, PII redaction, and preventing prompt injection attacks while maintaining system usability.

Cloud-Native Architecture on AWS

What to coverGiven the requirement for AWS-based solutions, explain how you would integrate Amazon Bedrock with existing microservices. Discuss the use of event-driven patterns (e.g., SQS, SNS) and infrastructure as code (Terraform or CDK) to ensure scalable, reproducible deployments.

Evaluating AI Model Performance

What to coverDescribe your methodology for the automated evaluation of AI models and prompts. Explain how you incorporate human-in-the-loop workflows to validate outputs before full-scale production deployment.

Build-versus-Buy Decision Framework

What to coverWhen evaluating AI platforms versus custom-built solutions, what criteria do you use? Suggestion: Focus on long-term maintenance, data sovereignty, integration complexity, and the specific business value of proprietary versus off-the-shelf capabilities.
