This includes but is not limited to the installation, modification, and testing of new and/or upgraded applications (packages or homegrown), operating systems, file structures, hardware, communication devices, and productivity tools. Applies analysis techniques and procedures to gather and then translate business requirements into functional/technical specifications and designs. Using functional specifications and designs, produces all or part of the deliverables. Maintains databases and application system code. Specific Duties & Responsibilities Analysis & Requirements Gathering Under guidance define business/clinical/education problems by meeting with clients to observe and understand current processes and the issues related to those processes. Provide written documentation of findings to share with the client and other IT colleagues. Gather system requirements by meeting with clients and researching existing technology to understand the business requirements for new applications. Design & Development Develop detailed tasks by analyzing project scope and milestones for projects to ensure product is delivered quickly according to software lifecycle standards. Write functional/technical specifications by taking the provided system requirements, putting them into functional and technical descriptions for use by programmers and business analysts to develop technical solutions. Develop/change data input, files/database structures, data transformation, algorithms, and data output by using appropriate computer language/tools to provide technical solution for application development tasks. Document code and associated processes by adhering to development methodologies, adding code comments and appropriate documentation to various knowledge-based system(s) to simplify code maintenance and to improve the support. Testing & Documentation Create and document test scenarios using the appropriate testing tools to validate and verify application functionality. Test all changes by using the appropriate test scenarios to ensure all delivered solutions work as expected and errors are handled in a meaningful way. Author and maintain documentation by writing audience-appropriate materials to serve as technical and/or end-user references. Implementation & Maintenance Implement changes by adhering to the change management policies and procedures for any given project to communicate to all parties the nature, significance, and risk factors of the solution. Monitor changes and resolve problems by responding to problems as they occur, by reviewing all processing and output of the newly implemented solution, and by proactively ensuring the solution works successfully to satisfy the customer requirements and to provide a smooth transition to the new solution. Provide support by triaging and resolving issues to ensure prompt, effective service. Other duties as assigned. In addition to the duties described above Working with SQL and relational databases.
