What GDIT Can Offer You

  • Opportunity to engineer technical solutions in support of critical scientific research
  • Opportunity to implement best practices and influence technology change 
  • Ability to see the business impact of technology. 
  • Ability to expand your cloud infrastructure knowledge and adoption of DevOps best practices.

  • Supporting and configuring LAMP stack applications for custom developed applications using technologies such as Apache, Tomcat, Java, Python, MySQL, MariaDB, and PostgreSQL.
  • Breaking down monolithic applications hosted on-prem into a microservice architecture hosted in containers or serverless workloads.  This is part of an effort to refactor applications and shift hosting from on-prem to the AWS cloud.  
  • Contributing to on-going efforts to develop standardized, hardened, and compliant infrastructure services for self-service consumption such as Linux server images, Docker Images, RDS Aurora, and Email using AWS Simple Email Service (SES).
  • Troubleshooting and resolving service impacting outages for Linux servers and Linux applications identified through problem incidents reported by users or product owners and monitoring systems alerts. 
  • Joining a morning stand-up or team meeting to report your accomplishments, plans for the day, and any roadblocks you encountered.  Your team will do the same, giving you an opportunity to understand and contribute to other ongoing initiatives.

  • Experience designing and implementing technologies following NIST standards, such as SP 800-53, SP 800-190, and SP 500-291 using tools such as CISecurity, Open SCAP, or RedHat CS2 security benchmarks.
  • Experience analyzing solutions components, understanding systems integration challenges, and identifying technology gaps in current components that must be resolved to reach future performance targets and functionality requirements in cloud infrastructure. 
  • Must be able to obtain a NIH Public Trust

Desired Qualifications:

  • Experience breaking down monolithic applications into microservices and hosting them in Docker containers. 
  • Experience with infrastructure as code and automation/configuration management using either Cloud Formation or Terraform to define infrastructure standards for cloud services.
  • Minimum of three years experience with AWS services. Examples include commonly used services such as EC2, S3, Route 53, and RDS, as well as more niche services, such as Elastic Beanstalk, Cloud Front, and Guard Duty.
