Full Job Description
**Who we are:** Fuse builds innovative communications, networking, and computing solutions that improve the sharing of information, video, text, and voice among operators distributed throughout the airborne, maritime, and ground environments. We are a technology firm creating in-house software, network and hardware solutions that support our noble cause of advancing warfighter capabilities with elegant, user-focused communications, networks, and software systems. **About This Role:** Fuse is seeking a Systems Test Engineer IV to lead integration, validation, and operational evaluation activities across complicated tactical communication systems. This role is responsible for reducing uncertainty through evidence generation and ensuring delivery decisions are informed by validated system behavior rather than assumptions. Working within Fuse's Define–Design–De-risk–Deliver iterative development model, the Systems Test Engineer IV transforms mission intent, architectural hypotheses, and integration risks into structured validation strategies that produce actionable evidence. This role collaborates across software, networking, RF, cyber, hardware, and systems engineering disciplines to mature system readiness and support mission success. Integration and test are treated as learning activities—not cleanup phases. Successful candidates will be comfortable operating in environments where architecture evolves through experimentation, progressive integration, and operational feedback. **Key Responsibilities** **Define** * Contribute to Design Reference Missions (DRMs) by identifying mission-critical behaviors, operational stressors, and validation objectives * Help translate mission intent into measurable system outcomes and readiness criteria * Participate in identification of mission risks, integration uncertainties, and validation priorities **Design** * Lead development of validation strategies aligned to mission threads, architectural intent, and system risk posture * De
