Responsibilities

We are seeking a highly motivated Staff Fuel System Engineer to support the design, development, integration, and fielding of a next-generation aircraft system for Project Ranger. This position requires a balance of technical rigor, rapid decision-making, and hands-on engineering to efficiently transition concepts into operational capability. The ideal candidate is comfortable solving complex problems, taking ownership, working within an accelerated aircraft development environment, and is motivated by getting meaningful capability into the hands of operators quickly.
Serve as the Responsible Engineer for the aircraft fuel system, owning requirements, architecture, interfaces, hardware, and technical decisions from concept through operational deployment.
Design, size, and integrate fuel tanks, pumps, valves, plumbing, venting and pressurization systems, filtration, level sensing, and associated fuel system hardware.
Analyze fuel system performance across the aircraft operating envelope, including pressure and flow requirements, transient engine demand, elevated-G maneuvering, tank depletion, slosh, vapor pressure, cavitation, vapor ingestion, and thermal effects.
Lead technical design reviews, supplier engagements, and hardware procurement while ensuring the fuel system meets performance, mass, thermal, reliability, safety, and mission requirements.
Plan and execute component, subsystem, and vehicle-level testing, including instrumentation, procedures, data acquisition, performance validation, and flight readiness.
Analyze ground and flight data to validate system performance, quantify margin, identify anomalies, and drive hardware or operational improvements.
Lead failure investigations and root cause efforts using analysis, inspection, testing, and data to develop effective corrective actions.
Work hands-on with design engineers, technicians, propulsion, controls, airframe, manufacturing, supply chain, test, and flight teams to build, integrate, troubleshoot, and iterate flight hardware.
