The client is picturing a hands-on Guidewire ClaimCenter developer with a robust Java/API integration background, not a configuration analyst or functional consultant.
The repeated emphasis on Gosu, Spring Boot, microservices, and SAPI/PAPI/XAPI signals a developer who builds and maintains the integration layer around ClaimCenter, not someone who only configures business rules or screens.
The explicit list of protocols and tooling (REST, SOAP, JSON, XML, YAML, Swagger/OpenAPI, Postman) points to a candidate who owns integration design end to end, from documentation to testing.
This role should not be confused with a Guidewire Business Analyst, a QA/testing specialist, or a ClaimCenter functional configurator: the client is explicit about "designing, developing, documenting, and supporting" web services, which is a build role.
The client has since confirmed active urgency: they are ready to move quickly and meet candidates, resolving the earlier contradiction between "no current vacancy" and the ASAP submission date. Work mode is confirmed as hybrid with two days per week in office, and mandate duration is confirmed at 6 months, renewable. Guidewire ACE certification has been reconfirmed by the client as a distinct criterion.
