Job description

Position: Sr. Agentic AI Platform Architect

Location: Fort Worth, Texas (Hybrid)

Job ID: 180323

Responsibilities

• As Sr Eng 2 Architect on the Agentic System Layer (ASL) team, candidates will define and drive the technical architecture for clients’ agentic AI platform.
• Day-to-day responsibilities include:
• Designing and evolving the architecture for multi-agent orchestration systems, tool-use frameworks, and LLM integration pipelines
• Establishing patterns for agent reliability, observability, and guardrails at production scale
• Leading technical design reviews and producing architecture decision records (ADRs)
• Collaborating with ML engineers and software engineers to ensure platform components are scalable, secure, and maintainable
• Evaluating and integrating emerging agentic AI frameworks (e.g. LangGraph, CrewAI, Semantic Kernel, AutoGen)
• Defining API contracts, data flow patterns, and integration standards across the AI platform ecosystem
• Mentoring engineers on best practices for building production-grade AI systems.

Top 3 Mandatory Skills and Experience

• 10 plus years software architecture experience with at least 3 years designing AI/ML platform systems, including hands-on experience with LLM orchestration frameworks (LangChain, LangGraph, Semantic Kernel, or similar).
• Deep expertise in distributed systems design, microservices architecture, event-driven patterns, and API design (REST/gRPC), with strong proficiency in Python and at least one of Java/Go/TypeScript
• Production experience building and deploying agentic AI systems or LLM-powered applications at scale, including prompt engineering, tool-use patterns, RAG pipelines, and agent reliability/observability.

Nice to Have Skills

• Experience with Kubernetes/container orchestration, cloud platforms (AWS/Azure/GCP), MLOps/LLMOps tooling, vector databases (Pinecone, Weaviate, pgvector), knowledge graphs, airline/travel domain experience, TOGAF or similar architecture certification, experience with multi-agent system design patterns and agent evaluation/benchmarking frameworks.

Describe a great candidate that you are looking for and what skills and experience they will have

• A great candidate is a seasoned architect who has shipped production agentic AI systems - not just prototypes.
• They can whiteboard a multi-agent orchestration system, debate tradeoffs between different LLM routing strategies, and then jump into code to prove out a design.
• They understand that agentic systems at airline scale need bulletproof reliability, graceful degradation, and real observability.
• They have opinions backed by experience, they push back on bad ideas constructively, and they make the engineers around them better.

Additional Details

• Candidate must have 10 plus years of experience.
• Candidate must work onsite Tuesdays - Thursday, virtually Mondays and Fridays.
• This assignment is ending on 12/31/2027
