Software Test Engineer

Hold an active DoD Secret clearance and know your way around a test case? Read on.

Sienna Systems is seeking a driven Software Test & Automation Engineer to join the Joint Interoperability Test Command (JITC) Test Evaluation and Certification II Services (TEC II) team at Fort Huachuca, Arizona, supporting Developmental Test & Evaluation (DT&E) of the Defense Logistics Agency’s Enterprise Contract Writing Module (ECWM).

ECWM is the cloud-based contract writing and management platform standardizing how the Department of Defense’s “4th Estate” agencies run procurement worldwide — from requirements and source selection through contract award. The software you test moves real contracting operations across the enterprise.

You will sit on a working Agile team alongside SCRUM developers, system engineers, and program management, designing and executing the functional, integration, and regression testing that decides whether a release ships — with room to grow the automation side of the practice.

• Analyze and validate user stories, technical specifications, and functional requirements to ensure comprehensive test coverage.
• Design, write, and execute detailed test cases and test scenarios for functional, integration, and regression testing phases.

• Work closely with teammates, SCRUM teams, software developers, and program management to ensure alignment on quality goals and project deliverables.
• Design, execute, and maintain functional test cases to validate that application features meet established requirements and acceptance criteria.
• Assist in the development, maintenance, and execution of automated testing scripts to increase test coverage and reduce manual testing effort.
• Actively participate in sprint planning, daily stand-ups, sprint reviews, and retrospectives to provide testing status and quality metrics.

Required Qualifications

• Interim DoD Secret security clearance or above
• Bachelor’s degree and at least 4 years of experience; or an Associate’s degree and at least 6 years of experience, or 8 years of experience.

• Excellent communication skills — written, verbal, and interpersonal
• Ability to prioritize and execute tasks within restricted timeframes
• Detail-oriented, able to work independently, self-motivated, and a proactive team player

• SCRUM, Leading SAFe, T&E, test automation, and/or AI in T&E certifications
