About Our Team:

Within Expedia Group, at the foundation of every successful initiative is DATA.
Our team at Expedia Group is looking for a proven, entrepreneurial, hands-on technical leader at a senior level who will define and implement the vision for AI automated data and platform engineering that will power EG’s hyper personalized traveler experiences.
Our team is at the heart of Expedia Group's AI transformation working on data and platforms powering Destination domain and Marketing Communications while also being one of the AI platform development team taking AI initiatives to production for Enterprise Data Platform. We work on data experiences for over 700 million travelers annually across Expedia, Hotels.com, Vrbo, and our entire brand portfolio. We're a dynamic group of data engineers, full stack engineers, and product experts who are pioneering the use of generative AI and agentic systems to revolutionize how travel data is processed, understood, and activated at massive scale.

We're not just building data pipelines – we're also creating autonomous AI systems that understand destination and marketing domains for traveler intent, predict needs, and enable magical travel experiences in real-time. As early adopters of cutting-edge agentic AI frameworks and MCP (Model Context Protocol), we're building self-optimizing systems that process petabytes of data daily while continuously learning and evolving.

Our team culture celebrates innovation, where experimentation is encouraged, failures are learning opportunities, and breakthrough ideas come from everyone. This is a rare opportunity to shape the future of travel technology while having immediate impact on how millions of people experience the joy of travel.

In this role, you will:

• Design, build, and evolve complex, highly available, and performant services, APIs, and data models that power customer and partner-facing products across multiple domains.

• Lead end-to-end implementation of features and systems, including low-level design, API design, data modeling, coding, testing, deployment, and operational readiness for services you own.

• Drive technical decision-making within your area by evaluating trade-offs, proposing pragmatic solutions, and mentoring other engineers on engineering best practices, code quality, and system design.

• Safely integrate and operate AI/ML‑enabled solutions that improve outcomes, including familiarity with AI-driven systems, tools, or workflows and applying AI/ML concepts to real world products where appropriate.

• Collaborate closely with product, design, and other engineering teams to translate business and customer requirements into scalable technical solutions that can be reused across multiple services and domains.

• Champion operational excellence by improving reliability, observability, and incident response processes, and by continuously optimizing system performance, cost, and security.

Minimum Qualifications:

• Bachelor’s degree in Computer Science or a related technical field; or Equivalent related professional experience.

• 8+ years of relevant professional experience.

• Proven experience owning the design, implementation, and operational support of one or more services or components, including APIs, data models, and integrations with other systems.

• Proven experience in AI engineering.

• Strong foundation in computer science fundamentals, including data structures, algorithms, object-oriented or functional design, and system design for distributed or service-oriented architectures.

• Demonstrated ability to collaborate in a cross-functional environment, breaking down complex requirements into incremental, high-quality deliverables with a focus on testing, reliability, and maintainability.

Preferred Qualifications:

• Experience designing and evolving service architectures at scale, including clear API contracts, resilient integrations, and data modeling that supports high-throughput, low-latency workloads.

• Track record of driving AI enabled technical initiatives that improve reliability, observability, or cost efficiency across multiple services or teams, including ownership of on-call readiness and incident reviews.

• Proficiency in applying data-driven approaches to engineering decisions, such as using metrics, logs, and experimentation to guide performance tuning and feature rollout strategies.

• Hands-on experience integrating or extending AI/ML‑enabled capabilities in production systems, including responsible use of AI services, evaluation of model impact, and safe automation of workflows, with the ability to guide others on safe and effective AI adoption.

• Depth in at least one technical domain (such as backend services, full stack, data-intensive systems, or platform components) with the ability to quickly learn adjacent technologies and contribute across domain boundaries.
