Responsibilities: Design, Code and Implement Microservices component as per the requirement using Spring Boot. Use Java 8 features to write functional and concurrency programming. Use Maven as build and project management central repository tool. Follow TDD approach and write Junit test cases for code coverage. Code coverage is validated against Sonar Cube. Build front-end page using Angular 8 and render the response from backend RESTful API services. Document the business process using low-level design and sequence diagram.

Microservice endpoints should be performance test using Jmeter and the endpoints response time (SLA) should be less than 300 ms. Coordinate with the QA team to finalize on the test case for relevant endpoints and the UI components. GIT is used a source repository and as a developer we should create/work on a feature branch designated for the particular task and release management should be followed.

T.ROWEPRICE, OWINGS MILLS, MD Jan 19 Jan 20 J2EE Developer/Lead Description: A.O.R. is a Central Repository Portal creates an intuitive way to view and edit backdated trades that will accommodate various reporting and tracking needs. An opportunity exists for TRP to extend using a single, consolidated desktop to the Financial Institution Services (FIS) group. At the highest level, TRP currently defines a desktop as a means to present an associate with one stop for information needed to interact with an individual, either customer or prospect in Retail, a retirement plan participant in Retirement Plan Services (RPS), or a client in FIS. FIS does not currently have a single, consolidated desktop that can be used to provide one stop for information needed to service client requests. To date TRP has implemented Vantage as the Retail desktop, Synergy as the RPS desktop (within the Participant Service Center), and Touchpoint to provide customer relationship information for Institutional sales groups and FIS. Although the Retail and RPS desktops look slightly different and service different types of individuals, ie a customer / prospect or a retirement plan participant, the desktops provide similar functionality.

This enables Plan Sponsors to continue providing drug coverage to their Medicare-eligible retirees at a lower cost. The PRP System processes payment requests originating from both the RDS Secure Website (RDS Users) and the PRP Payment System Interface (RDS Operations staff). In processing payment requests, the PRP System ensures that participant eligibility (debarment) and payment validation are performed on all payment requests in accordance within established program guidelines. The PRP System performs all EFT/ACH functions between the RDS Program and its commercial bank (CitiBank) on behalf of CMS. These functions include both pre-notes and wire transfer payments. The PRP System also provides the ability for RDS Operations staff to report pre-note and wire transfer payment failures, which in turns triggers automatic notification of incorrect banking information to the Plan Sponsor by way of existing communication paths with the RDS mid-tier.

It is an integral part of the foundation and core of the overall RPS Strategy execution. Through our definition of what is logical and configurable for our offerings, we are able to solidify our competitive edge in the marketplace. With MPI T Rowe is able to create and modify certain products by considering various categories and corresponding answers for them and come up with ranking which allow easy determination of product in 5 categories Preferred, Less Preferred, Allowed by authorization and Not authorized and Other. OMR program was to stand up a new, clean instance of the Omni record keeping platform. The existing Omni instance is characterized by years of incorrect or underutilization of the core Omni product, T. Rowe price specific global and plan specific customizations, and inconsistent utilization of data elements within the platform. Essentially we are in a state where we have a record keeping product but are not using it to its potential as we have customized the product beyond recognition. One of the technology goals of OMR is "more to core" which is the notion that we should push record keeping functionality to Omni and use the core product as intended as opposed to relying upon T. Rowe specific customizations that are not as full featured as the base offering provided by the core Omni product. Single Point of Entry, also known by the acronym S.P.O.E., is a foundational technology. It will allow RPS to holistically and efficiently manage plan level information by providing a centralized, governed and trusted single source of plan level data.
