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 II 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. In this role, you will: Design, build, test, and maintain reliable software components that deliver high-quality customer and business outcomes. Translate product and technical requirements into maintainable solutions, applying sound engineering practices across the software development lifecycle. Develop clear low-level designs, APIs, data models, and integrations that support scalable, secure, and dependable services. Investigate and resolve complex technical issues, improve system performance and reliability, and contribute to operational excellence. Collaborate effectively across engineering, product, and technical domains while applying transferable skills to multiple problem spaces. Safely integrate and operate AI/ML-enabled solutions that improve outcomes, while building familiarity with AI-driven systems, tools, workflows, and the application of AI/ML concepts to real-world products.
