Tester - Senior

Provide a short description of the Position: The position supports the UI Job Assist Tool (JAT), a initiative to develop and integrate secure APIs and Model Context Protocol (MCP) services between the core UI system of record and an AI-enabled Job Assist Tool. The Senior Tester will perform functional, integration, API, microservice, AI-tool, and MCP validation to ensure reliable and secure read/write data exchange.

Provide a list of the day-to-day tasks to be performed by the Selected Candidate: • Develop and execute functional and integration test scenarios for the Al-enabled UI Job Assist Tool. • Test read/write REST APIs and Java microservices used to exchange data between the core UI system and the Job Assist Tool. • Perform Model Context Protocol (MCP) validation, including server/client interactions, tool invocation, request/response handling, and error conditions. • Validate business rules and data-integrity controls designed to prevent corrupt or unapproved Al-generated data from being written back to the UI system. • Execute positive, negative, boundary, regression, and end-to-end tests across APIs, microservices, MCP components, and Al integrations. • Create and maintain test cases, test data, traceability, defect documentation, and test execution results. • Use API testing tools to validate REST endpoints, payloads, schemas, authentication, error handling, and response behavior. • Query backend data stores as needed to confirm accurate processing and persistence of data. • Collaborate with Programmers, Data Architects, Cloud Engineers, vendor technical teams, and business SMEs to investigate defects and clarify expected behavior. • Support performance and scalability testing for workloads associated with approximately 1,500 concurrent users and document-heavy processing. • Validate security-sensitive integration behavior in a regulated UI environment and support knowledge transfer to State staff.
