This mid-level Systems Engineer role focuses on defining, designing, and de-risking complex tactical communication systems integrating hardware, software, networking, and RF components. The engineer will contribute to mission-intent refinement, system architecture and interface definition, trade studies, modeling/simulation activities, and integration testing—capturing and validating expected vs.… observed behavior to surface architectural assumptions and feed insights back into system refinement. The role requires 4–6 years of experience integrating across hardware, software, networking, and RF domains in iterative, fast-paced environments where requirements and architecture evolve as uncertainty is reduced.
