• Analyze user requirements to derive software design and performance requirements.\n
• Design and code new software and modify existing software to add capabilities.\n
• Debug software, correct defects, adapt applications to new hardware, and improve software performance.\n
• Develop and implement algorithms that meet or exceed system functional and performance standards.\n
• Design or implement complex algorithms subject to strict timing, system-resource, or interface constraints.\n
• Design, develop, and modify software systems using appropriate scientific analysis and mathematical models to evaluate design outcomes and consequences.\n

\n \nIntegration, Data & System Engineering\n \n \n

• Integrate existing software into new or modified systems and operating environments.\n
• Develop data queries for existing or proposed databases and data repositories.\n
• Design and implement complex database and data-repository interfaces and queries.\n
• Develop software solutions by analyzing system performance standards, system flows, data usage, work processes, and technical problem areas.\n
• Confer with systems engineers and hardware engineers to derive software requirements and understand project limitations, capabilities, performance requirements, and interfaces.\n
• Contribute to system-design decisions involving hardware/software tradeoffs, software reuse, COTS/GOTS alternatives, and requirements allocation.\n
• Coordinate software-system installation and monitor equipment functioning to ensure operational specifications are met.\n

\n \nTesting, Quality & Engineering Practices\n \n \n

• Review and test software components for adherence to design requirements and document test results.\n
• Develop and execute test procedures for software components.\n
• Resolve software problem reports.\n
• Perform quality control on team products.\n
• Write and review software and system documentation.\n
• Recommend and implement improvements to documentation and software-development process standards.\n
• Apply software-development and software-design methodologies appropriate to the development environment. \n

\n \nTechnical Leadership\n \n \n

• Serve as a team lead at the level appropriate to the software-development process and project.\n
• Oversee one or more software-development teams and help ensure work is completed within the constraints of the development process being used.\n
• Coordinate technical activities with users, systems engineers, hardware engineers, and other engineering disciplines.\n
