Tech Lead Software Engineer

• AI Platforms Pod
  In the AI Platforms Pod, you’ll set technical direction for the core platforms that enable Southwest’s AI and machine learning capabilities. You’ll lead system design for distributed cloud services and APIs, ensuring platform components are scalable, secure, and reusable across Teams. This role includes leading design reviews, raising engineering standards across testing, CI/CD, and reliability, and partnering closely with Product Teams to deliver roadmap outcomes while managing technical debt. You’ll work hands‑on with AWS services, Infrastructure as Code, event‑driven integrations, and observability tools to ensure platform services are production‑ready and easy to operate. Your leadership helps create a strong foundation that allows Teams across the Company to develop, deploy, and experiment with AI confidently and at scale.

• AI Platform Operations Pod
  In the AI Platform Operations Pod, you’ll lead advanced support engineering for AI and agentic platforms, bridging the gap between platform development and operational excellence. You’ll guide L2/L3 engineering efforts—driving automation, improving reliability patterns, and shaping how platform issues are detected, triaged, and resolved. This role focuses on setting a high technical bar for support engineering through observability, automation‑first practices, and “shift‑left” improvements that reduce operational load over time. You’ll mentor a growing Team of Engineers and help define effective L1/L2/L3 handoff models, while working closely with Platform and Product Partners to ensure AI systems continue to deliver value as they evolve. Your work ensures Southwest’s AI platforms remain dependable, resilient, and ready to scale.
