Job description

What Impact You'll Have

GRVTY's team provides tactical data engineering solutions. We embed skilled Data Engineers, Data Scientists, and ETL Developers directly into intelligence analyst groups to be their go-to data wranglers. We develop new tools, code, and services to execute data engineering activities. Our engineers work to collect, process, and feed analytic tools, turning data into intelligence in response to immediate mission needs, with direct impact on real world situations. You will see your work used here on a daily basis, and you'll have the opportunity to support a variety of Sponsor mission organizations and mission partner organizations.

This is a time of development and growth on the program, with an increasing number of missions being supported. The work is high impact and important, and the customer moves quickly. The environment is fast-paced, flexible, and open to innovation - you'll have more latitude here in choosing how to achieve results than on many other projects. The customer cares more about what you can do as opposed to your years of
experience, and work hours are typically quite flexible - roll up your sleeves, get things done, and no one cares much about the specific hours that you work. The work space itself is also quite nice, and there is an excellent cafeteria! The tech stack on this team is rather huge and includes Python (Pandas, numpy, scipy, scikit-learn, standard libraries, etc.), Python packages that wrap Machine Learning (packages for NLP, Object Detection, etc.), Linux, AWS/C2S, Apache NiFi, Spark, pySpark, Hadoop, Kafka, ElasticSearch, Solr, Kibana, neo4J, MariaDB, Postgres, Docker, Puppet, and many others. Work on this program takes place in McLean, VA and in various field offices throughout Northern VA (we cannot support remote work) and requires a TS/SCI + Polygraph clearance (acceptable to this customer).

What You'll Be Owning

GRVTY is seeking a Senior Software Developer with a TS/SCI + Poly clearance (applicable to this customer) to join one of our top projects in Tysons, VA. The developer, with a minimum of 10 years' experience,  will support the full lifecycle development (analyze, design, develop, deploy, maintain) of innovative and interactive web, video and multimedia training products. The individual will be responsible for product research, programming/authoring, interface design, testing and quality control. Products also include web-based training, SharePoint and websites, multimedia applications, video productions, graphic design, and print products.

The ideal candidate requires demonstrated experience with:

  • Linux
  • Amazon cloud, AWS and use services, like S3 and EC2
  • Apache Webserver and Apache Tomcat
  • Development languages: Java, PHP, HTML, CSS, MySQL and Javascript
  • VS Code
  • Configuring, implementing, and maintaining the Enterprise Application Auditing Tool, Enterprise Application MFA Solution (OAuth), and RBAC (Role Based Access Control)
  • Bash Scripting
  • Developing and supporting automation and orchestration processes for IAM services. Understanding of IAM governance frameworks, platforms, RBAC, group policy management, and privileged access management (PAM) tolls.

What You Must Have

  • Active TS/SCI with Polygraph Clearance (applicable to this customer)
  • Ten (10) years of experience executing software development activities
  • A bachelor's degree in Computer Science, Computer Information Systems, or Computer Engineering
  • Demonstrated expertise with AWS infrastructure security and access controls
  • Demonstrated expertise adapting equipment and technology to serve user needs and technology design
  • Ability to convey technical information to non-technical individuals to teach navigation of Github, Linux-based OS, and AWS and use services, such as S3 and EC2
  • Demonstrated understanding of software development best practices, including version control, testing, and debugging

What Would Be Nice to Have

  • Demonstrated migration experience from on-premises services to the AWS platform using migration tools
  • Demonstrated experience maintaining JAVA and PHP applications on Windows
  • Demonstrated experience with maven or Gradle
  • Demonstrated experience with AWS Secrets Manager
  • Three years of experience contributing to software development activities and or projects within the IC
