About the position

We have an IMMEDIATE NEED for an ETL Java Developer SME to provide Agile DevOps support to mission-critical systems. As an ETL Java Developer on this program, you will have the opportunity to build strong systems, software, and cloud environments and provide operations and maintenance for critical systems. The candidate will provide technical expertise and support in the design, development, implementation, and testing of customer tools and applications in support of Extracting, Transforming, and Loading of data into an enterprise Data Lake. Based in a DevOps framework, you will participate in and/or direct major deliverables of projects through all aspects of the software development lifecycle including scope and work estimation, architecture and design, coding, and unit testing. This role requires the development of custom code/scripts to quickly extract, triage, and exploit data across domains and data stores. In this position, you will be responsible for designing and implementing a large-scale ingest system in a big data environment. You will be required to read, analyze, and digest what the enterprise needs to accomplish with its data and design the best possible ELT process to support those objectives. You will also be responsible for recommending methodologies to optimize the visualization, organization, storage, and availability of large-scale data in support of enterprise requirements. Participation in software programming initiatives to support innovation and enhancement will be expected, utilizing technologies such as HTML, CSS, JavaScript, Java, Python, SpringBoot, and Hibernate. Additionally, you will develop and direct software system validation and testing methods using Junit and Katalon, and develop and integrate custom-developed software solutions to leverage automated deployment technologies. You will analyze (through proof of concept, performance, and end-to-end testing) and effectively coordinate Infrastructure needs driven by developed software to meet customer mission needs. Supporting the Agile software development lifecycle following Program SAFe practices is essential, as is the use of industry-leading DevOps tools like GitHub, Jenkins, and Unix bash scripting. You will document and perform systems software development, including deployment of build artifacts across different environments leveraging GitFlow constructs, and leverage the Atlassian tool suite like JIRA and Confluence to track activities. Communication of key project data to team members and building team cohesion and effectiveness will be crucial, as will holding meetings with PMO and enterprise stakeholders.
