Senior Specialist - Architecture

About the role

As a Software Engineer on the Agentic System Layer (ASL) team, you will build and maintain the core platform components that power American Airlines’ agentic AI systems.

Responsibilities

• Develop and maintain agent orchestration services, tool registries, and execution runtimes
• Build APIs and microservices for LLM integration, prompt management, and agent lifecycle management
• Implement observability, logging, and monitoring for agentic workflows
• Write comprehensive tests (unit, integration, end-to-end) for platform reliability
• Collaborate with architects on design decisions and with ML engineers on model integration
• Participate in on-call rotations for production support of the AI platform
• Contribute to CI/CD pipelines, infrastructure-as-code, and deployment automation

Requirements

• 5+ years software engineering experience with strong proficiency in Python, plus working knowledge of at least one of Java, Go, or TypeScript
• Hands-on experience building production REST/gRPC APIs and microservices
• Solid experience with cloud platforms (AWS or Azure preferred), containerization (Docker/Kubernetes), CI/CD pipelines, and infrastructure-as-code (Terraform, CloudFormation, or Pulumi)
• Working experience with LLM integration patterns, prompt engineering, or AI/ML application development
• Familiarity with frameworks like LangChain, LangGraph, or similar orchestration tools

Nice-to-have Skills

• Experience with event-driven architectures (Kafka, EventBridge)
• Vector databases
• Observability tools (Datadog, Splunk, OpenTelemetry)
• Agent evaluation frameworks
• FastAPI/Flask, async Python
• Redis/caching patterns
• Airline or travel industry experience

What Makes a Great Candidate

A great candidate is a solid mid-level to senior engineer who writes clean, testable code and has genuine curiosity about AI/ML systems. They do not need to be a deep ML expert, but they should understand how LLMs work, what agentic patterns look like, and how to build reliable services around non-deterministic components. They take ownership, write good tests, communicate clearly in code reviews, and are comfortable operating production systems.
