Aerodynamics and Flight Mechanics Engineer II

About this Role

Varda is seeking an Aerodynamics and Flight Mechanics Engineer to support operation of Varda's current vehicles and the development of Varda's next reentry vehicle – from rarefied entry, to hypersonic maneuvering, and subsonic terminal approach. The candidate must have experience running high speed computational fluid dynamics (CFD) simulations and supporting wind tunnel campaigns. Exposure to 6DOF flight dynamics modeling, and experience developing flight rules is strongly preferred. The ideal candidate should have been involved in the aerodynamic development of a currently flying vehicle from cradle to grave.

Responsibilities

Own the aerodynamic and aeroheating database development across the full flight envelope, from free-molecular rarefied entry through hypersonic maneuvering to subsonic terminal approach, serving as the authoritative aeroscience input to GNC, TPS sizing, and mission analysis

• Plan, execute, and reduce data from wind tunnel campaigns; reconcile ground test results with CFD predictions and update vehicle databases with traceable, well-documented revisions
• Run high-fidelity CFD and DSMC simulations of hypersonic and subsonic flows using tools such as Fun3D, LAURA, DPLR, US3D, SPARTA, DAC, and CBAero; build structured and unstructured meshes in Pointwise
• Characterize static and dynamic stability, develop 6DOF simulation inputs, and contribute to flight rules and vehicle-level performance models
• Synthesize aerodynamic evidence from CFD, wind tunnel, and flight telemetry into a coherent, traceable database that supports GNC, TPS sizing, and mission analysis
• Lead post-flight aerodynamic reconstruction and performance assessments; identify where preflight predictions diverged from reality and drive model updates that make the next mission sharper
• Collaborate across disciplines: GNC, structures, TPS, and mission planning, to deliver flight-ready aeroscience products and serve as the aerodynamics voice in every cross-discipline design discussion

Basic Qualifications

• BS degree in engineering or physics and 3+ years of relevant industry experience, or a relevant PhD and 1+ years of relevant industry experience
• Meaningful contribution to the aerodynamic development of a hypersonic vehicle that has flown, or is on track to fly within the next 5 years
• Experience analyzing aerodynamic data from test, CFD, flight, and other sources and documenting findings rigorously
• Experience running CFD and DSMC simulations of hypersonic and subsonic flows (Fun3D, LAURA, DPLR, US3D, SPARTA, DAC, CBAero)
• Comfortable building structured and unstructured meshes in Pointwise
• Proficiency in MATLAB or Python
• Excellent written and verbal communication skills with a demonstrated ability to translate complex aeroscience findings for cross-disciplinary audiences
• This position requires ability to obtain and maintain a security clearance, which is issued by the U.S. government. U.S citizenship is required to obtain a security clearance

Preferred Skills and Experience

• Advanced degree in Aerospace or Mechanical Engineering, specializing in aerodynamics or fluid mechanics
• Hands-on wind tunnel campaign experience, including test planning, execution, and data reduction
• Direct ownership of aerodynamic and aeroheating databases for a flying vehicle
• Familiarity with modeling vehicle dynamics in POST2 or similar 6DOF tools
• Experience sizing ablative or non-ablative TPS
• Experience with flight reconstruction and post-flight performance evaluations
• Technical breadth in adjacent disciplines (GNC, avionics, software, structures)

Pay Range

• Salary Range: Eng II: $119,543- $152,749/per year
• This role is on-site in El Segundo, CA
• Leveling and base salary is determined by job-related skills, education level, experience level, and job performance
• You will be eligible for incentives in the form of stock options and/or long-term cash awards
