Cloud Software Developer 3

Lentech•Annapolis Junction, MD

About The Position

The Cloud Software Developer develops, maintains, and enhances complex Big-Data cloud systems based on documented requirements. The role contributes to back-end processing, analysis, and indexing, and applies expertise in cloud computing, the Hadoop ecosystem, Java applications, distributed computing, information retrieval, and object-oriented design. The developer may work independently or as part of a team; reviews and tests software components against design requirements; documents test results; resolves software problem reports; and uses software development and design methodologies appropriate to the environment. The position provides input to software components of system design, including hardware/software trade-offs, software reuse, use of COTS/GOTS products in place of new development, and analysis and synthesis of requirements from the system level to individual software components. Work also involves cloud architecture, implementation and management of multi-node installations, debugging distributed frameworks, information assurance, SIGINT-related systems and dataflows, and configuration management. An active and current TS/SCI with FSP through NSA is required. A bachelor's degree in computer science or a related discipline is required, with stated substitutions for relevant experience, a master's degree, and Cloudera certification. The stated salary range is $215,731 to $230,393.
