A Test Lead coordinates all efforts associated with test, to include test-driven development and implementing automation for various elements of system test.  This approach places a strong emphasis on all aspects of test (unit, integration, and system-level) to ensure STR is fulfilling the end-user's operational needs, thus enabling the success of the overall mission.  Ensuring all facets of system test are accounted for in the end-to-end software development and deployment can significantly improve the impact of STR software. 

We are seeking experienced candidates – preferably, established technical leads with experience as a test lead on a software development program and skill interfacing with teams of developers.

What you will do:

• Lead the development team in designing and implementing integration tests for innovative software services in an agile DevSecOps environment
• Collaborate with program leadership to prioritize test planning and execution activities
• Ongoing work includes developing and maintaining automated system and regression tests and working with program management/staff to identify key system-level test cases
• Hands-on experience with ability to quickly grasp overall system architecture picture is essential

Who You Are: 

• Ability to obtain a Top Secret security clearance with SCI eligibility, for which U.S citizenship is needed by the U.S government
• BS in Computer Science, Information Technology, or related technical field with a minimum of 7+ years of relevant experience. Equivalent experience will be considered.
• Experience with relevant technologies, including:
  • Python
  • Kafka
  • RESTful services
  • Gitlab, specifically Gitlab CI/CD and understanding pipelines
  • Kubernetes (good familiarity with kubectl and experience putting together k8s yml config files)
  • ELK stack tools
  • Docker and docker-compose
  • Java applications (e.g., deployment/configuration)
  • xUnit-based test frameworks, primarily pytest, PyUnit, Jest, and Junit
  • Web-based UI test automation tools (e.g., Selenium, Playwright) 

Even Better:  

• Active Security Clearance at the Top Secret level with SCI Eligibility
• Advanced Degree in Computer Science, Information Technology, or related technical field
• Located near STR offices in Woburn, MA, Arlington, VA, or San Diego, CA, Denver, CO or willing to relocate
• Demonstrated ability to work across DevOps and development teams to find solutions to enable automated testing
• Demonstrated test framework/infrastructure debugging skills, especially debugging microservices deployed to a cloud infrastructure (leverages multiple skills including kubectl, ELK, Docker knowledge
• Ability to fully understand the architecture of the system under test and to identify weak/failure points
