Senior Hypersonic Propulsion Engineer (Scramjet/CFD)

The Johns Hopkins University Applied Physics Laboratory; Laurel (MD); On-site; USD 100,000 - 245,000; Full time

Job summary

The Johns Hopkins University Applied Physics Laboratory (APL) is seeking a Senior Aerospace Propulsion Engineer to advance hypersonic propulsion for DoD programs. You will design and analyze scramjet-like flowpaths and apply high-fidelity CFD to challenging reacting flows.

You will frame problems, defend methods, and turn incomplete data into actionable recommendations while mentoring other engineers. APL offers a collaborative environment in the Baltimore-Washington area with strong benefits.

Qualifications

• Bachelor's degree required in Aerospace/Mechanical/Physics or related field.

Responsibilities

• Lead design and analysis of scramjet inlet, isolator, combustor, and nozzle flowpaths.
• Apply high-fidelity CFD with finite-rate chemistry to compressible reacting flows.
• Investigate shock trains, unstart, fuel-air mixing, ignition, and combustion stability.
• Plan and assess verification, validation, mesh- and model-sensitivity studies.
• Compare CFD predictions with ground-test, wind-tunnel, and flight data.
• Diagnose unexpected results and recommend design or test changes.
• Improve computational workflows, meshing, and HPC usage.
• Communicate conclusions to sponsors and teams.
• Provide technical leadership and mentorship to engineers.
