Full Description
About Us
Marriott International Inc., headquartered in Bethesda, Maryland, USA, was founded in May 1927 by J. Willard Marriott and Alice S. Marriott with a modest nine-seat A&W root beer stand. Guided by the family's leadership and core principles, Marriott International today has grown into a global hospitality giant, operating approximately 9,000 properties and over 30 leading brands in more than 140 countries and territories.
Role Title: Senior Quality Engineer II
Position Summary
We are looking for a highly skilled Senior Performance Engineer to join our Quality Engineering team, focused on end to end performance engineering rather than traditional execution only performance testing. This role goes beyond running load tests and publishing results. The Senior Performance Engineer is expected to proactively identify, investigate, and help resolve performance risks by continuously analyzing application behavior across environments using observability data, logs, and performance metrics.
This individual will develop a deep understanding of the application ecosystem, including frontend, backend services, databases, integrations, and cloud infrastructure. By reviewing Dynatrace telemetry, logs, traces, and code paths, the engineer will partner closely with application, platform, and architecture teams to diagnose bottlenecks, explain root causes, and recommend performance and scalability improvements.
Success in this role requires strong engineering fundamentals, the ability to read and reason about Java and Python code, and a broad architectural mindset to evaluate system behavior holistically—not just under load, but in real production like conditions.
This role is not limited to executing performance tests; it is an engineering role focused on understanding how systems behave, why performance issues occur, and how to prevent them.

Experience with Test Automation and DevSecOps tools (e.g., Git, JIRA, Ant, Maven, Jenkins)
Undergraduate degree in an engineering or computer science discipline and/or equivalent experience/certification
Strong performance engineering mindset with experience analyzing production like telemetry, logs, and distributed traces, not just test execution results.
Ability to read, understand, and reason about Java and Python code to identify performance risks and optimization opportunities.
Solid understanding of distributed system architecture, including microservices, APIs, databases, messaging, and cloud infrastructure.
Experience using observability platforms (e.g., Dynatrace) for continuous performance analysis, root cause investigation, and system optimization.
Proven ability to translate technical findings into actionable recommendations for engineering and architecture teams.
Demonstrated ability to move from “test results” to “engineering insights”, influencing design and implementation decisions.
