Common roles include data engineers, semantic web developers, and ontology specialists.

Job description

Position Summary
We are seeking a Middleware Software Engineer / Developer to support the modernization of a proprietary middleware broker application used to interface with IBM Engineering Lifecycle Management, formerly IBM ELM.
The current middleware tool acts as a broker that pulls and processes data using SPARQL queries for reporting into IBM ELM. The underlying database has already been converted to a SQL relational database, and the next phase of the project is to update the middleware broker application so it can pull, process, and store data using SQL instead of SPARQL.
The ideal candidate will have strong experience supporting, developing, and modifying middleware tools, with hands-on development experience in Java, C++, and C, along with a working understanding of SPARQL, SQL, and relational database technologies.
Key Responsibilities
  • Support and enhance a proprietary middleware broker application used in connection with IBM ELM.
  • Modify existing middleware functionality to pull, process, and store data from a SQL relational database.
  • Replace or refactor legacy SPARQL-based query logic with SQL-based data access and processing.
  • Analyze existing Java, C++, and C code to understand current broker behavior and data flows.
  • Work with converted SQL database structures to ensure data is retrieved and stored accurately.
  • Support reporting workflows that feed data into IBM ELM.
  • Troubleshoot and resolve middleware application issues.
  • Develop, test, and validate changes to the broker application.
  • Support configuration management and version control processes.
  • Assist with documentation of system changes, data flow logic, and application updates.
  • Provide support for Microsoft Excel-based reporting tools, including macros where applicable.
Required Qualifications
  • Strong experience as a Middleware Engineer with Hands-on experience supporting, developing, or updating middleware applications or integration tools.
  • Proficiency with Java.
  • Experience with C++ and/or C application development.
  • Strong working knowledge of SQL and relational database concepts.
  • Ability to understand existing legacy code and refactor application logic.
  • Basic understanding of SPARQL and semantic query concepts.
  • Experience working with applications that retrieve, process, transform, or store data between systems.
  • Strong debugging, troubleshooting, and problem-solving skills.
  • Experience working in a configuration-managed software environment.
Preferred Qualifications
  • Experience with Apache Jena.
  • Experience supporting tools that interact with IBM Engineering Lifecycle Management / IBM ELM or other PLM tools.
  • Experience migrating applications from semantic query models, such as SPARQL, to relational SQL-based data models.
  • Microsoft Excel experience, including macro development and support.
  • Experience with reporting tools, data extraction, or engineering lifecycle/reporting environments.
  • Familiarity with proprietary or internally developed broker, middleware, or integration tools.

Flexible work from home options available.
