Systems & Software Test Engineer

Nothing the DoD fields reaches a warfighter on a vendor's word. Someone has to stand the system up, run it against the requirement, and put their name on what it actually does. At the Joint Interoperability Test Command, that is the whole mission — and that is this job. Sienna Systems is hiring a Systems & Software Test Engineer to support Verification, Validation, and Accreditation (VV&A) work on the JITC Test Evaluation and Certification II Services (TEC II) program, in support of the MAMBA task order at Fort Huachuca, Arizona. This is hands-on work with real ownership. You will stand up and maintain the test environments yourself, operate and troubleshoot the systems under test, write the scripts that measure whether they hold up, and produce the evidence and reports that back the accreditation decision. It is a small team, so the scope is broad — you will not be handed one narrow slice of a test plan and left there. What You'll Do Work with analysts, software and systems engineers, and OT&E personnel to document and exercise VV&A processes for assigned applications and systems Operate and troubleshoot applications and systems during VV&A efforts, and produce test reports and supporting evidence Prepare and present VV&A analysis results Develop scripts and tools to assess the performance parameters identified in VV&A plans, and document the results Gather, prepare, and present application and system tool-use metrics Coordinate the setup and maintenance of VV&A systems Install and configure applications and systems in compliance with program instructions, verifying functionality and documenting configurations and results Maintain accurate VV&A documentation, ensuring traceability and compliance with industry standards Gather and analyze user feedback on the support provided, and implement improvements as needed What You Need An interim or active DoD Secret security clearance in place on your first day (we are not able to start you on a pending investigation) CompTIA Security+ certification A Bachelor's degree and at least 2 years of relevant experience — or 6 years of equivalent professional experience in place of a degree Strong hands-on troubleshooting of applications and systems Scripting ability for performance assessment and test tooling Experience working in Agile Scrum Clear, careful writing — a real share of this role is documentation other people depend on Nice to Have Prior VV&A or DoD test and evaluation experience Familiarity with Section 508 Accessibility Standards Experience coordinating across teams and managing VV&A evidence Experience developing documentation and user manuals Location and Schedule Hybrid.
