Coronavirus is on everyone's mind with the effects being felt around the world. The markets are volatile, and we're all concerned for the health and safety of our families, friends, and colleagues. Please know that we're taking all necessary measures to safeguard our employees, customers and the communities in which we live, including following all recommended best practices around social distancing.

With that in mind, in an abundance of caution, we are canceling all face to face career events, such as job fairs and open house events. In the coming days and weeks, we will be hosting career events virtually, using our online chat tools so that we may continue our hiring practice safely and securely. You can find available virtual career events at

We are using telephone meetings and online chats via Brazen to conduct interviews and hiring discussions, and we are offering options for video interviews so that you can have a virtual face to face meeting with your potential new leader. We do not conduct interviews or extend offers via text or chat based social media, such as WhatsApp or MySpace.

Leidos will never ask you to provide payment-related information at any part of the employment application process, nor will Leidos ever advance money as part of the hiring process. And Leidos will communicate with you only through emails that are generated by automated system. If you receive an email purporting to be from Leidos that asks for payment-related information or any other personal information, please report the email to Chris Scalia, Leidos’ Senior Vice President of Talent Acquisition, at [email protected].

As a company, as a country, as a world, we have confronted challenging moments before. We are confident that, guided by our values and the strength of our community as well as the commitment we have to the important work we do each day, we will find our way through this time together. We will do this with the care and concern for one another and the common good that defines. Please keep those impacted by the virus in your thoughts.

Job Description:

Leidos is looking for a mid-career level engineer with an Aerospace background to support our growing work in the King of Prussia office.  This is a technical engineering position to use computational fluid dynamics (CFD), thermal response, and signature modeling tools to predict flowfields and both EO/IR and RCS signatures of air vehicles.  Work will focus on hypersonic aerodynamics, aeroheating, material thermal response, and signatures as well as non-linear aerodynamics at subsonic and supersonic speeds.

Be part of a close knit team and be mentored by world class experts.  The Aerophysics group operates in a small team environment where individual creativity is rewarded and continuous learning is the norm.  Our engineers directly interact with customers to ensure high quality and timely deliverables are achieved.

The successful candidate will be able to use computational fluid dynamics modeling and simulation to generate aerodynamic and aeroheating loads for subsonic, supersonic, and hypersonic vehicles.  The candidate will perform gridding, computational fluid dynamics simulations, flow visualization, and workflow programming, using both local and DoD Supercomputing Resource Centers for massive deployment and monitoring of solutions and harvesting of results.  The candidate will utilize signature analysis tools to generate signature databases of vehicles over given flight trajectories.

It is highly desired that the candidate also has experience with development of new business, including interactions with potential customers, generation of white papers and proposals, and familiarity with costing of proposed efforts.


Experience Level:  The candidate would be expected to be able to perform CFD and signatures analysis with minimal supervision.  The candidate should also be able to grasp the big picture and make decisions about how to proceed with analysis with minimal supervision.  The candidate should have 5+ years of experience with a BS or MS in Aerospace Engineering (or similar) or a PhD in Aerospace Engineering (or similar) and 2-3+ years of experience.

Knowledge:  Experience with subsonic, supersonic, and hypersonic computational fluid dynamic models with software such as Cart3D, Kestrel, FUN3D, US3D or equivalent is required.   Knowledge of turbulence modeling and chemical equilibrium and non-equilibrium modeling is required.  Experience with block structured and unstructured gridding with software such as Pointwise or equivalent is required.  Experience with signature generation software such as SPURC, PARCS, OSC, and FLITES is desired.  Ability to utilize DoD DSRC capabilities including deploy/run/harvest workflow scripting is required.  Experience with differing levels of modeling fidelity (low, medium, high) and material response modeling (thermal, ablation, erosion, etc.) is desired.

Communication Skills:  Successful candidates should be able to effectively communicate with Leidos colleagues and interact regularly with customers.  Must present both verbal and written status on a regular basis and travel to customer meetings to present results.

Engineering Skills:

  • Numerical gridding (Pointwise or similar)

  • Scripting to enable numerical codes to communicate and to run in a batch fashion (Python, Matlab preferred)

  • Computational fluid dynamics for subsonic / supersonic / hypersonic flows (Kestrel, FUN3D, or similar)

  • Thermal response simulation (temperature, ablation, and/or erosion response)

  • Post processing CFD data

  • Operating on supercomputing clusters

  • Signature generation (SPURC, PARCS, or similar)

Education:  Requires a BS or MS in Aerospace, Mechanical, or similar discipline and 4+ years of experience in CFD or a PhD with 2-3+ years of experience.

Clearance:  Must be a U.S. Citizen with active Secret clearance.

Travel:  Attend customer meetings to present results, estimated < 10%.
