How this role works

You join the bench. You apply with your weekly hours and start time. We set your hourly rate from your résumé, and we may name you on proposals that match this role. If we don't win, you owe nothing.
A contract is awarded. The award funds the team named in the proposal. Your engagement begins at the hourly rate we agreed on.
You work remote, paid from the contract. ~120–600 hrs per funded award — and if no award ever funds, you owe nothing and lose nothing.

What you'll do

Build and run large-eddy simulations of hypersonic nozzles and shock tubes, from grids and boundary conditions through post-processing
Model how acoustic, entropy and vorticity disturbances form and travel through the nozzle into the test section
Compare results against tunnel and shock-tube measurements and tell us plainly where the simulation holds and where it doesn't
Write up methods, grid studies and findings clearly enough that a Government reviewer can check them

Required qualifications

Hands-on LES or DNS of compressible, high-speed flows, with results you can show
Working knowledge of shock-capturing schemes, wall modeling, and turbulent inflow or disturbance boundary conditions
Experience running CFD codes at scale on HPC clusters
U.S. citizen or lawful permanent resident (U.S. person)
Willing to be named on a federal proposal with a one-page resume, and to sign a short letter of commitment

Preferred qualifications

Hypersonic wind tunnel or shock-tube experience, including freestream disturbance or boundary-layer transition studies
US3D, VULCAN, CharLES, SU2, OpenFOAM or an in-house high-order solver
Able to work on-site in northwest Florida for part of the effort
PhD in aerospace or mechanical engineering, or an equivalent research record

Compensation & structure

1099 consulting engagement. $45–$100 per hour; we set your rate from your résumé and experience. Hours are funded by federal contract awards — this seat is scoped at roughly 120–600 hours per funded award, fully remote.

1. Cover letter. In your own words, tell us about yourself: what guides you (for many of us here, that’s our faith in God), your background, and why this role interests you. *

2. Describe the high-speed CFD project most like this role: the flow and facility you simulated, the solver and grid you used, how you handled shocks, walls and disturbances, how you checked results against data, your role, and the result. *

Availability

Pay for this role: $45–$100 an hour, set by your experience.

Hours per week you could give on an awarded contract (all part-time, up to 30) *

If you are named and we win, will you be able to start within a few weeks? *
