• Use industry-standard tools for simulation test and evaluation to include Wireshark, simulation protocol analysis, and GFE and Commercial Computer Generated Forces (CGFs).

• Assist in detailed analysis of network and computational system performance including latency, bandwidth, jitter, and system occupancy measures.

• Help develop and maintain test plans and procedures to document and drive test activities.

• Draft comprehensive test reports based on completed integration, test, evaluation, and verification tasks performed.

• Assist in the development of CONOPS and multiple COAs for implementation and deployment of the evaluated simulation capabilities.

• Contribute to other areas of the engineering life cycle to include requirements review and assessment, training operations support, and basic system administration functions.

• Produce well-defined, concise, and directed test procedures and test cases under the guidance of senior engineers.

• Support program and team processes by using tools from the Atlassian Suite of products to include JIRA, Confluence, Bitbucket, Bamboo, and X-Ray.

• Participate in peer reviews, test bed maintenance and updates, and programming, testing, and debugging activities.

• Write and maintain scripts and support application (PowerShell, Cygwin, VBasic, etc.) programs, to enable efficiencies in test artifact creation and task execution.

• Help identify production and non-production application issues, assist in developing solutions, and implement necessary changes.

To be successful in this role, you will have:

• A bachelor’s degree in an applicable STEM curriculum (e.g., Data Analysis, System Engineering, Math, Computer Science, Physics, etc.) or similar.

• 8 years of engineering experience performing test, integration, SW development, or embedded systems engineering activities.

• Experience with military simulation integration test DIS IEEE1278.1 or HLA IEEE 1516 protocols, or similar communications or data protocols (SIP, VOIP, JREAP, etc).

• The ability to obtain a TS/SCI and SAP/SAR.

• Experience supporting DoD customers and personnel in a technical capacity.

• Familiarity or experience with development, test and evaluation of military simulation training or operational systems.

• Must possess, or obtain within six months, a DoD 8140 IAT Level II or higher (i.e. Security+, CySA+, CISSP)

• Up to 10% travel

This position is contingent upon your ability to obtain/maintain/transfer your Secret clearance.

Additional desired experience and skills:

• An active DoD Secret Clearance with ability to obtain TS/SCI and SAP/SAR.
