Introduction to the team:

Reviews Distribution (one of three tenets — Acquisition, Management, Distribution of Expedia Group's Reviews platform) owns how traveler reviews get surfaced and consumed across EG's brands (Expedia, Vrbo, Hotwire, COMET) and product lines (Lodging, Cars, GT, LX). We're mid-way through Reviews Unification and a multi-year effort consolidating fragmented, LOB-owned review services into One Reviews Platform, and rebuilding review forms into a single, shared, high-performance experience across web, mWeb, and native app.

In this role, you will:

• Design, build, and evolve complex, highly available services and applications, including system design (low-level design), API contracts, and data models that are resilient, scalable, and maintainable.

• Lead end-to-end ownership of one or more critical services or components within a broader domain, from technical design and implementation through deployment, monitoring, and ongoing operational excellence.

• Write high-quality, well-tested code, establish coding standards, and perform deep code reviews that improve reliability, performance, security, and long-term maintainability across the team.

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

• 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.

• Diagnose and resolve complex production issues, drive root cause analysis and long-term fixes, and improve observability, automation, and operational processes across services and domains.

Minimum Qualifications:

• Bachelor’s degree in Computer Science, Engineering, or a related technical field, or equivalent practical experience.

• 5+ years of professional software development experience building and operating production services or applications, including ownership of at least one significant service or component.

• Strong proficiency in one or more modern programming languages and frameworks, with proven ability to design APIs, data models, and low-level system components for scalable, distributed systems.

• Demonstrated experience owning the full lifecycle of services (design, implementation, testing, deployment, monitoring, and operations) within a team or domain environment.

• Familiarity with AI-driven systems, tools, or workflows and the fundamentals of integrating such capabilities safely into existing applications or services.

Preferred Qualifications:

• Experience designing and evolving service architectures at scale, including complex API ecosystems, data modeling for high-volume systems, and low-level designs that balance performance and maintainability.

• Proven track record leading technical delivery for multi-service or cross-team initiatives, influencing technical direction, and driving standardization across a domain.

• Depth in operational excellence practices such as observability, incident management, capacity planning, reliability engineering, and continuous improvement in production environments.

• Hands-on experience integrating or extending AI/ML-enabled capabilities in production systems, including safely operating these solutions, optimizing their impact, and managing dependencies on AI platforms or services.

• Experience using data-driven approaches (experiments, metrics, and analytics) to inform design decisions, validate solutions, and iterate on products and services across different functional areas or domains.
