About This Role
Fuse is seeking a Senior Systems Engineer to lead mission definition, architecture clarity, and integration risk reduction across complicated tactical communication systems. This role elevates systems engineering maturity and ensures predictable system behavior under operational stress.
Chief Engineer (ChEng) Designation
Depending on mission scope, system complexity, and organizational need, this role may be designated as a Chief Engineer (ChEng). When assigned, the ChEng is responsible for maintaining coherence across mission intent, architecture, integration strategy, technical risk posture, and delivery readiness throughout the Define–Design–De-risk–Deliver lifecycle. The ChEng serves as the technical authority for system readiness, mission effectiveness, and engineering execution, driving uncertainty reduction through modeling, simulation, experimentation, and progressive integration.
Key Responsibilities
Define
Establish and maintain Design Reference Missions (DRMs) that anchor mission intent and guide hypothesis formation
Translate customer intent into system-level behaviors
Identify mission-level risks and architectural uncertainties
Design
Lead system architecture definition across disciplines
Define critical interfaces and integration strategies
Conduct and lead trade studies to support architecture decisions
Frame Epics as architectural hypotheses, explicitly stating assumptions, mission impact, and risk posture
Ensure risks and opportunities are surfaced and managed at the architecture level rather than at execution detail
De-risk
Design and drive modeling and simulation strategies
Lead early integration experiments to reduce uncertainty
Ensure traceability from mission intent through validation
Own system-level risk posture and drive cross-discipline alignment to reduce integration uncertainty early in the lifecycle
Drive integration learning cycles that validate or invalidate architectural assumptions
Ensure Stories and integration events produce evidence tied directly to mission intent
Deliver
Establish objective delivery readiness criteria based on integration risk retirement rather than schedule milestones alone
Ensure integration and verification activities are aligned with mission threads
Ensure delivery readiness is based on validated system behavior under stress conditions, not artifact completion
Communicate confidence levels in system performance based on evidence generated through spiral iterations
Establish criteria for delivery readiness based on risk posture
Drive resolution of cross-discipline issues impacting system behavior
Ensure traceability from mission intent through formal validation
Communicate system risk posture to program and technical leadership
When designated as Chief Engineer (ChEng), serve as the technical authority for mission readiness, engineering execution, and cross-discipline architectural coherence across the system lifecycle
