Current job opportunities are posted here as they become available.

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.

Why You’ll Want This Role:
  • $92,000 - $98,000 based on experience
  • Hybrid schedule; no relocation needed if you are already in southern Arizona
  • Long-standing JITC TEC II program team supporting an established DoD customer
  • 401(k) with 4% matching, immediate vesting, no restrictions
  • 3 weeks Paid Time Off plus 11 Federal Holidays
  • Real runway to move from functional testing into test automation
Key Responsibilities:
  • 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.
  • Identify, document, and track software defects, at times collaborating with development teams to recreate issues or perform root-cause analysis.
  • 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:
  • Active DoD Secret security clearance
  • Bachelor's degree and at least 4 years of experience; or an Associate's degree and at least 6 years of experience; or at least 60 semester hours of formal education working toward a Bachelor's degree and at least 6 years of experience; or 8 years of experience. One year of experience may be substituted by 15 semester hours completed toward an Associate's or Bachelor's degree.
  • At least one professional certification in the area of specialization
  • Understanding of Agile/SCRUM principles and experience working within sprint-based development cycles
  • Excellent communication skills - written, verbal, and interpersonal
  • Ability to prioritize and execute tasks within restricted time frames
  • Detail-oriented, able to work independently, self-motivated, and a proactive team player
Preferred Qualifications:
  • SCRUM, Leading SAFe, T&E, test automation, and/or AI in T&E certifications
  • Experience supporting DT&E of DoD business systems
  • Hands-on experience building and maintaining automated test scripts

Salary: $92,000 - $98,000 based on experience
