GNC Engineer

Correlate CFD predictions against wind tunnel, direct-connect, ground-test, and flight-test data.

Help identify, investigate, and document sources of discrepancy between analysis and test results.

Provide pre-test CFD predictions to support test planning, test-point selection, and success criteria.

Package CFD-derived data products in formats that are useful to downstream vehicle-performance, trajectory, and flight-controls teams.

Maintain rigorous, reproducible documentation for each major analysis campaign, including: Mesh-generation procedures Boundary conditions Solver configuration and settings Convergence criteria Validation and correlation basis Post-processing methodology

Mesh-generation procedures

Boundary conditions

Solver configuration and settings

Convergence criteria

Post-processing methodology

Work closely with Aerodynamics, Propulsion, Flight Dynamics & Controls, Test, and Manufacturing teams.

Translate design questions into well-posed CFD studies and translate simulation results into practical design recommendations.

Participate in technical and program design reviews, providing CFD-based support for aerodynamic and propulsion decisions.

Coordinate CFD study scope, priority, and turnaround requirements against program milestones.

Partner with computing-infrastructure support on HPC access, software licensing, and computational-resource allocation.

B.S. or higher in Aerospace Engineering, Mechanical Engineering, or a related discipline.

2–5 years of CFD experience , including relevant graduate research, internships, or professional engineering work on air vehicle, propulsion, or munition programs.

Hands-on experience with at least one major CFD solver, such as: ANSYS Fluent STAR-CCM+ FUN3D Kestrel CFD++

ANSYS Fluent

STAR-CCM+

FUN3D

Kestrel

CFD++

Experience with meshing tools and mesh-generation strategies for internal and external aerodynamic flow domains.

Strong foundation in compressible aerodynamics and propulsion flow physics from subsonic through high-supersonic regimes.

Proficiency in CFD post-processing, data reduction, visualization, and automation.

Ability to communicate technical results clearly, including assumptions, uncertainty, and limitations.

U.S. citizenship and eligibility to obtain and maintain a U.S. government security clearance.

You are comfortable in the details of a simulation: mesh quality, boundary conditions, turbulence modeling, convergence behavior, and solver stability. You know a CFD result is only valuable when it is technically sound, clearly documented, and delivered in a form the next engineer can use.

You bring strong fundamentals, intellectual honesty, and the judgment to flag a result when it does not look right. You are eager to deepen your expertise in propulsion integration and flight-vehicle aerodynamics while taking on increasing ownership of analysis campaigns.

As Tiberius scales through Series A and into full-rate development, this engineer will take on progressively greater responsibility—from independently leading CFD studies to growing into a senior aerodynamics or propulsion engineering role.
