SOA/OSB Developer

• Maintain the Oracle Service Bus (OSB) composite services and Oracle views through which the system obtains new participant information from integrated systems. [The composite services are defined in the Oracle Service Integration Framework (SIF). The OSB manages requests from these systems and sends back responses to the systems using the composite services.]
• Support the ongoing data governance activities & needs of both the applicant system and the systems exchanging data with it. This includes data architecture documents and data models monthly as systems evolve.
  • Data ETL & Synchronization Processes – Changes to the systems will happen periodically throughout the year as part of several monthly releases.
  • OSB WebServices (PUT/ GET/ SEARCH/QUICK SEARCH (Fuzzy or Exact match)) for pushing and pulling data from MDM application.
  • JMS Setup (Queues & Bridges) for pushing MDM data change details to downstream application.
  • PL/SQL procedures, triggers, packages and queues.
  • Java/SIF UserExists.
• Address Trouble and Support Tickets.
• Apply patches to WebLogic application/ servers (WebLogic CPU Quarterly Patches) to Sandbox, Dev and SQT domains. Create migration documents and work with client resources to deploy the patches.
• Perform upgrades and the installation and testing of hotfixes for the Oracle Service Bus.
• Participate and assist when there is:
  • A scheduled Production Change (monthly)
  • A critical vulnerability and/or patch required (estimated 1-4 times per year)
  • A production support issue (estimated 0-4 times per year)
• Support security patching in coordination with the DBA and infrastructure teams.
• Respond to user questions and reported incidents.
• Provide system training and guidance.
• Maintain technical documentation.
• Monitor and respond to user requests and associated trouble tickets and resolving all trouble tickets in a timely manner.
• Work with business users in an ongoing process of data cleansing and de-duplication records by aiding in the development of algorithms and processes as defined by client staff.
• Perform the full range of software engineering tasks necessary to sustain and enhance the system, following industry best-practices and client standards and processes for designing, testing, deploying and documenting across all systems tiers in conjunction with impacted teams.
• Deliver monthly releases using agile methodology.
• Upgrade Java in MDM WebLogic domains.
• Support requirements analysis, Change Request (CR) tracking, design, development, unit testing and integration testing, support for UAT, and managing the release process for system enhancements.
  • Application Enhancements – Define scope and size required changes to the system in coordination with the COR, business users and requirements analysts, then design and implementapproved plan.
  • API Enhancements and Consuming Application Integration Support – Work with consuming applications and their business analysts on defining, scoping, scheduling, designing and implementing updates to the API and OSB capabilities.
  • Help reduce the average amount of time required for the system’s response to a request from the consuming applications.
  • Major Stack Upgrades– There will be major stack upgrades approximately every two years. Functional system-stack upgrades are typically delayed until their stability has been tested and debugged by other organizations before being used in Production.
  • Improve processes for reducing the number of duplicate records –Engage in an ongoing process of designing and implementing processes to reduce the number of duplicate records in the system, in conjunction with client’s business requirements and processes. This will reduce the total number of records in the system and simplify reporting and maintenance requirements.
  • A potential project could involve migrating system access to an open-standards API-based approach vs. Oracle Service Bus.
• Analyze weekly Vulnerability report from Infrastructure team and check for new vulnerabilities for system domains that need to be addressed.
• Help develop architecture diagrams.
• Ensure SSL certificates and systems remain current (examples: LDAP LDS ROOT Cert, Osbcert – Internal certificate, Pay.gov [PROD Cert])
