Description

Software Engineer 1

The Software Engineer (SWE) develops, maintains, and enhances complex and diverse software systems (e.g., processing intensive analytics, novel algorithm development, manipulation of extremely large data sets, real-time systems, and business management information systems) based upon documented requirements. Works individually or as part of a team. Reviews and tests software components for adherence to the design requirements and documents test results. Resolves software problem reports.

Utilizes software development and software design methodologies appropriate to the development environment. Provides specific input to the software components of system design to include hardware/software trade-offs, software reuse, use of Commercial Off-the-shelf (COTS)/Government Off-the-shelf (GOTS) in place of new development, and requirements analysis and synthesis from system level to individual software components.

Requirements

The Level 1 Software Engineer shall possess the following capabilities:

• Analyze user requirements to derive software design and performance requirements
• Debug existing software and correct defects
• Provide recommendations for improving documentation and software development process standards
• Design and code new software or modify existing software to add new features
• Integrate existing software into new or modified systems or operating environments
• Develop simple data queries for existing or proposed databases or data repositories
• Write or review software and system documentation
• Serve as team lead at the level appropriate to the software development process being used on any particular project
• Design or implement complex database or data repository interfaces/queries
• Develop or implement algorithms to meet or exceed system performance and functional standards
• Assist with developing and executing test procedures for software components
• Develop software solutions by analyzing system performance standards, confer with users or system engineers; analyze systems flow, data usage and work processes; and investigate problem areas
• Modify existing software to correct errors, to adapt to new hardware, or to improve its performance
• Design, develop and modify software systems, using scientific analysis and mathematical models to predict and measure outcome and consequences of design
• Develop and support a near real time messaging infrastructure, Messaging products include: TIBCO EMS, Active
  
  MQ, Artemis, and Kafka
• Provide Tier III support on the Data Transport Systems (DTS) software
• Develop and support the DTS portfolio (DTS supports complex event processing using FOSS tools to collect infrastructure monitoring/metrics, and generate threshold based and temporal based alerting, DTS components send status information back to storage areas where quires can be made)
• DTS products include but are not limited to:
  Cloud storage areas:
  Apache Accumulo (Apache Zookeeper, Apache Hadoop) (U) Oracle DMBS (U) Real time streaming:
  Storm (U) Distributed in-memory data Cache/Storage:
  Redis (U) Graph Compute engine/Query Interface apache Tinkerpop/Gremlin (U) Rules Engine: JBoss Drools (U) Apache Camel (U) Spring Framework: used extensively to standardize/simplify configuration logic control, data access, security, Web-tier, etc.
• Develop and support the GUI interface into the EMM
• GOTS developed applications include:
  Addition to FOSS messaging tools to run in the SIGINT environment (U) GUI to display metric/monitoring status and do common queries (U) Command line tools to interact with Accumulo Maintenance scripts to facilitate normal cluster functions (e.g. table splits, compactions, mergers, Local/HDFS directory cleanup, etc) (U) Java Multi-threaded applications
• Develop and maintain software in the development environment
• Use configuration management tool and repositories (i.e. Maven, Eclipse, GIT, Redmine)
• Support Multi-threaded applications

Qualifications:

• Four (4) years' experience as a SWE, in programs and contracts of similar scope, type, and complexity is required
• Bachelor's degree in Computer Science or related discipline from an accredited college or university is required. Four (4) years of additional SWE experience on projects with similar software processes may be substituted for a bachelor's degree

Additional contract or position specific required experience for this level (skills, technologies, expertise):

• Public Key Enabling (PKE). RESTful services and containers (Oracle Web Logic, JBoss, Tomcat). Java programming language. Perl programing language. Java EE. Secure web (SSL) and file encryption. LDAP (Red Hat directory) Java, Linux (CentOS), Modern IDEs (Intelli
  
  J, Eclipse, etc.) and Agile Scrum process
• One (1) year experience programming in the Linux, Unix or Windows operating system environment
• Two (2) years' experience writing/maintaining software in Java or GoLang language (U) One (1) year experience with the Spring Framework
• Two (2) years' experience using software development configuration…
