Job description

This is a temporary position. The assignment duration is through September 11, 2027. JOB SUMMARY Marriott International is a global hospitality company with a portfolio of 31 brands and more than 8,500 properties across 138 countries and territories. Diversity, inclusion, and the well-being of associates are fundamental to Marriott's values and business goals. The FLEX Software Engineer, Software Development Engineer in Test, AI, leads quality engineering for production conversational AI and intelligent search experiences. This role combines software development in test, browser and API automation, AI evaluation, performance engineering, accessibility validation, and production reliability to establish measurable quality standards and release-readiness gates for accurate, grounded, secure, reliable, and consistent customer experiences. CANDIDATE PROFILE Education and Experience Required • Bachelor's degree in Computer Science, Software Engineering, Information Technology, or a related field, or equivalent professional experience. • 2+ years of experience in quality engineering, test automation, or SDET roles. • Strong programming experience in Python, JavaScript, TypeScript, Java, or a comparable language, with hands-on experience in browser automation, API testing, automated test frameworks, performance testing, source control, code review, and CI/CD quality gates. • Experience testing conversational AI, generative AI, retrieval-augmented generation, intelligent search, chatbot, or agent-based applications, including non-deterministic evaluation, cloud-native systems, containers, Kubernetes, observability, accessibility, and cross-functional delivery. Preferred • Experience with commercial or open-source LLM evaluation platforms and with designing LLM-as-judge, deterministic, human-evaluation, prompt-testing, model-comparison, and retrieval-ranking workflows. • Experience with responsible-AI validation, red teaming, adversarial datasets, contract testing, service virtualization, workflow orchestration, asynchronous systems, canary deployments, and production smoke testing. • Experience with localization, accessibility, responsive and cross-browser testing, authentication and authorization testing, CORS, CSP, sensitive-data security testing, quality dashboards, and executive release-readiness reporting. CORE WORK ACTIVITIES • Defines and owns the automated quality strategy for conversational AI applications and intelligent search experiences. • Builds and maintains browser, API, integration, contract, smoke, regression, and end-to-end automated test suites. • Develops automated evaluations for response correctness, relevance, grounding, hallucination risk, retrieval quality, ranking quality, tool selection, and tool-call accuracy. • Validates multi-turn conversation consistency, safety guardrails, prompt-injection resistance, responsible-AI requirements, and sensitive-data handling. • Converts business scenarios, customer journeys, and production defects into reusable regression datasets and automated tests. • Develops performance, load, stress, spike, scalability, and reliability tests for AI applications and supporting services. • Establishes measurable quality baselines for latency, throughput, error rates, concurrency, resource utilization, and release readiness. • Integrates automated tests, AI evaluations, and quality thresholds into CI/CD pipelines and progressive-delivery workflows. • Builds automated pre-deployment and post-deployment smoke tests that validate critical customer and system workflows. • Manages test environments, synthetic data, fixtures, service mocks, test credentials, and repeatable test execution capabilities. • Analyzes failures and production issues using logs, metrics, distributed traces, automation results, and AI evaluation data. • Produces quality dashboards, defect insights, evaluation summaries, and release-readiness reports for engineering and business stakeholders. • Collaborates with Engineering, Product, Platform, Security, Accessibility, Quality Engineering, and Responsible AI teams to improve testability and prevent defects earlier in development. • Evaluates emerging AI quality-engineering tools and techniques and applies pragmatic approaches appropriate for production systems. At Marriott International, we are dedicated to being an equal opportunity employer, welcoming all and providing access to opportunity. We actively foster an environment where the unique backgrounds of our associates are valued and celebrated. Our greatest strength lies in the rich blend of culture, talent, and experiences of our associates.  We are committed to non-discrimination on any protected basis, including disability, veteran status, or other basis protected by applicable law.
