As a GMS team member, you will work as part of a fast paced, Agile development and implementation team to architect, design and develop an integrated solution that expands the foundational Integrated Data Architecture platform (Confluent and ELK platform). You will work alongside others in a matrixed organization across the project.
Primary Responsibilities:
  • Contribute to data engineering efforts by supporting the integration and enrichment of DISN network topology data for advanced data correlation and analytics.
  • Participate in technical discussions with internal and external stakeholders to support solution design and implementation.
  • Develop, test, and deploy data pipelines and integration solutions across distributed systems and cloud environments, using Python, JavaScript, Java, and SQL.
  • Assist in requirements gathering and collaborate with stakeholders to design and implement data enrichment pipelines, integrating diverse data sources into Confluent (Kafka) and Elastic platforms.
  • Develop and maintain Kibana visualizations and dashboards to support operational insights.
  • Support Kafka system integrations between Elasticsearch/Logstash and other systems.
  • Collaborate within Agile scrum teams, contribute to team deliverables, and share knowledge with peers.
  • Communicate and coordinate effectively with geographically distributed team members to achieve project objectives.
  • Troubleshoot and help resolve installation, infrastructure, and system issues; report and help mitigate technical risks.
  • Develop and maintain technical documentation, including DoD requirements, interface documents, and security compliance artifacts.
  • Ensure solutions comply with DoD security standards and guidelines, and support platform sustainment and reliability by addressing operational challenges as needed

Basic Qualifications:
  • Bachelor's degree from an accredited college in a related discipline, or equivalent experience/combined education, with 4-8 years of professional experience; or 2-6 years of professional experience with a related master's degree.
  • 4+ years of experience in software engineering, data engineering, or business/data analysis, preferably within Agile/Scrum teams.
  • Hands-on software development experience with Python, Java, SQL, and working knowledge of JavaScript and HTML.
  • Experience with distributed version control systems such as Git and Bitbucket.
  • Proficiency with data analytics and visualization tools, such as Kibana, Power BI, Tableau, and the ELK stack (Elasticsearch, Logstash, Kibana).
  • Experience designing, developing, and optimizing ETL processes and data pipelines, including integration with event streaming platforms like Kafka.
  • Background in data modeling, unification, and analytics to support data-driven projects.
  • Experience implementing application and system integrations, including Kafka and Elastic platform integrations.
  • Understanding of networking and internet protocols, with experience supporting network-centric or data-driven environments.
  • Experience developing and deploying software on UNIX/Linux command line platforms.
  • Strong communication and collaboration skills, with the ability to work effectively with cross-functional teams and stakeholders.
  • Experience with Agile project management and collaboration tools such as JIRA and Confluence.
  • Active Secret DoD Security clearance prior to start date.
  • Active Security+ Certification (or other applicable DoD 8570 IAT II certification) prior to start date.

Preferred Qualifications:
  • Experience with CI/CD techniques, containerized pipelines, and DevOps practices, including automating software delivery processes.
  • Familiarity with artificial intelligence and machine learning concepts, and interest in supporting the integration of AI/ML capabilities into data platforms.
  • Experience with data integration, storage, and analysis technologies such as Kafka, Elastic, Spark, or NiFi.
  • Hands-on experience with Kafka connector integrations and working knowledge of ksqlDB and Kafka Streams for real-time data processing.
  • Ability to develop software designs for streaming data applications, particularly using Kafka Streams or ksqlDB.
  • Experience developing and optimizing Kafka system integrations between Elasticsearch/Logstash and other systems.
  • Experience designing and implementing application deployment pipelines and developing software in containerized environments using Kubernetes and Docker.
  • Familiarity with Kubernetes deployment, Agile methodologies, and collaborative development tools.
  • Experience developing and deploying software in AWS cloud environments, including basic configuration of cloud infrastructure, networking, and security policies (GovCloud experience a plus).
  • Experience with full software lifecycle automation (design, development, testing, deployment), including production deployments.
  • Experience designing and building automated software testing pipelines using tools such as Ansible, Selenium, JMeter, Junit, or similar.
  • Experience developing and deploying software in DoD environments (DISA experience a plus), including building applications that meet DoD security standards and implementing security guidelines (e.g., STIGs).
  • Ability to support the development of DoD requirements, traceability matrices, project plans/schedules, and contribute to software systems engineering documents and interface documents (IDDs/ICDs).
  • Experience with Agile methodologies and Atlassian tools, including JIRA and Confluence, for project tracking and collaboration.
  • Ability to work effectively in remote, geographically dispersed teams, demonstrating strong communication and collaboration skills.
