Expedia Group is seeking a senior software engineer to shape an AI-native marketing platform that interfaces with agents and explores scalable architectures for data, services, and orchestration. You will partner with product, marketing, data science, and architecture leaders to drive high-impact engineering outcomes.

The role requires deep backend skills, experience with cloud systems (AWS), Kubernetes, and observable, cost-efficient services.

Hands-on experience with agentic / AI systems (LLMs, RAG, tools/MCPs, agent orchestration).
Demonstrated expertise in systems architecture, API design, and integrating third‑party products and platforms.

Responsibilities

Set technical vision for agentic marketing and own the outcomes.
Lead technical vision and target architecture for the agentic marketing platform - spanning data, services, workflows, experimentation, third-party APIs, and agent-facing surfaces.
Translate the agentic search strategy and investment roadmap into a sequenced, opinionated engineering plan with clear trade-offs and success criteria.
Partner with product, marketing, data science, SEO/AEO, and architecture leaders to align on priorities, interfaces, and ownership boundaries.
Work cross functionally with many internal and external teams to deliver outcomes with proven ability to influence without direct authority.
