Software Development Engineer III

We are the Model Lifecycle team inside Expedia Group's ML Platform. Our services help the MLS and MLE community across EG take use cases from idea to production model in the shortest time possible, with paved paths for training, registration, deployment, serving and monitoring.

As an SDE III you will own features end to end across one or two of these services, working in Python, Go, TypeScript and Kubernetes, with senior and principal engineers close by to pair, review and unblock. Hundreds of models across Expedia, Vrbo and Hotels.com run on what we help build, so the code you ship is felt quickly and good engineering habits (tests, observability, clear PRs) are valued as much as raw output.

We lean heavily on coding agents (Cursor, Claude Code and friends) to accelerate the delivery cycle: scaffolding services, drafting tests, reviewing PRs and keeping documentation in step with the code. You'll have space to learn how to get the best out of them and we'll look to you to apply good judgement on what lands in main.

Design, develop, test, deploy, and maintain reliable software services and applications that deliver measurable outcomes for customers and the business.

Apply software engineering principles across the development lifecycle, including low-level system design, API design, data modelling, implementation, testing, and code review.

Own technical solutions within a service or defined technical area, making sound engineering decisions that balance maintainability, scalability, reliability, and delivery.

Collaborate across engineering and partner teams to define requirements, resolve dependencies, and deliver cohesive solutions across multiple domains when needed.

Use operational data, monitoring, and production feedback to troubleshoot issues, improve system performance, and strengthen the reliability of owned services.

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

Expedia Group includes three flagship consumer brands - Expedia, Hotels.com, and Vrbo - along with a leading B2B travel business and travel advertising offerings. Across our brands and business, we help travelers explore the world with confidence and ease.
