  • Work with multiple COTS vendors to integrate products in multiple Linux environments and Windows.
  • Develop and maintain a rigorous versioning system that links training and validation for reproducibility.
  • Establish a DevOps environment and use DevOps tools such as, Jenkins, Kubernetes, Chef, and Terraform.
  • Test software using unit testing and/or automated test products such as Angular and Selenium, coordinating with partner teams as needed.
  • Adhere to the client-specific security practices and procedures.
  • Prepare and deliver program and user level documentation.
  • Support the development of security documentation for software environment establishment and interact with members of the technical team leads to understand the current system, subsystems, and component specifications.
  • Leverage experience to recommend changes to facilitate efficient and effective development.
  • Communicate and share expertise within and across the client’s organizational boundaries.
  • Work both independently and in small groups.
  • Apply current industrial software development best practices that include iterative and incremental project management techniques and agile software development.

Basic Qualifications:

  • Active TS/SCI with polygraph security clearance.
  • Ability to complete additional security screening processes as determined necessary by the client.
  • Typically requires BS degree and 8+ years of prior relevant experience.
  • Demonstrated experience with tools used with cloud services.
