Principal Software Developer (Java, JavaScript, Docker)

Designs, develops, troubleshoots and analyzes routine, complicated and difficult software programs for computer-based systems. Advises hardware engineers on machine characteristics that affect software systems, such as storage capacity, processing speed and input/output requirements. As required, provides inputs for documentation of new or existing programs.

The Level 3 Software Developer shall possess the following capabilities:

• Use object oriented techniques, programming languages, and standard methodologies, including classic development, waterfall, and agile methods (Extreme programming).
• Perform deployment, installation, maintenance, quality control monitoring, and implementation of software at Government specified locations.
• Maintain processes to log and track customer service requests.
• Maintain/develop software products to be used on a variety of platforms.

• Codes in eXtensible Mark-up Language (XML)/W3C XML Schema to C++ Compiler (XSD)
• Applies middleware technologies, such as enterprise service bus (ESB), CORBA, or Internet Communications Engine (ICE)
• Uses Integrated Development Environments (IDEs), such as JBuilder and/or Eclipse
• Design, develop, and document system and subsystem-level code. This includes support for system requirements, preliminary design, detailed design and specifications, data dictionaries, interface control/design documents, user help information/manuals, maintenance information/manuals, operations information/manuals, program code, quality assurance activities, and test.
• Develop customer requirements and information needs into software specifications that can be implemented
• Maintain/modify software code to add new features, correct errors, adapt to new hardware, or to improve system performance.
• Integrate with other signal repositories when prioritized by the Government.
• Perform system and unit level testing. This includes test plans and procedures, documentation of test results and development of special test code. Plan/conduct regression tests after each code modification, upgrade enhancement.
