Senior Engineer, Fluid Systems (R3818)

Shield AI • Dallas, TX

72d • $113,948 - $170,922

About The Position

We are seeking a Senior Fluid Systems Engineer to serve as the Responsible Engineer (RE) for fuel and oil systems on our V-BAT vehicle. This role demands cradle-to-grave ownership—from early system definition and architecture through build, test, flight, and operational support. You will lead the development of flight-critical fluid systems and ensure they perform reliably in high-consequence environments involving variable angles of attack (especially in VTOL), rapid transients, and demanding CONOPS. This role is hands-on, analysis-driven, and highly cross-functional—requiring collaboration with propulsion, design, airframe, manufacturing, and flight test teams.

Requirements

• Bachelor’s degree in aerospace engineering, mechanical engineering, or related field.
• 5+ years of experience owning or contributing to aerospace fluid systems.
• Strong foundation in fluid dynamics, thermodynamics, and fluid system component design.
• Demonstrated experience in system integration and hardware testing.
• Proficiency in analysis tools (e.g., Python, GFSSP, REFPROP, ANSYS).
• U.S. Citizenship or ability to comply with ITAR requirements.

Nice To Haves

• Experience with UAVs, tactical aircraft, or jet/rocket propulsion systems.
• Knowledge of compressibility effects, slosh dynamics, and G-loading considerations.
• Familiarity with system instrumentation and test data analysis.
• M.S. in Aerospace or Mechanical Engineering or a related discipline.

Responsibilities

• Serve as the RE for the design, integration, and validation of fuel and oil systems.
• Define system requirements, interfaces, and performance goals.
• Design and evaluate components for both compressible and incompressible flows, considering transients, heat rejection, and environmental extremes.
• Address challenges such as level sensing, vapor pressure, cavitation, vapor ingestion, slosh, and pressurization.
• Support and lead component and system-level ground and flight testing.
• Analyze test and flight data to validate performance, close margin, and refine designs.
• Collaborate with suppliers and internal teams to manage build and instrumentation requirements.
• Contribute to fault analysis, safety assessments, and operational reliability planning.

Benefits

• Pay within range listed + Bonus + Benefits + Equity
• Temporary benefits package (applicable after 60 days of employment)
