Primary Responsibilities.  

• Update current and create new aerospace modeling and simulation tools in MATLAB/Simulink, Python, C++. FORTRAN, or other similar programming languages.

• Develop and analyze 3DOF and 6DOF flight dynamics models to evaluate vehicle performance, stability, controllability, and mission effectiveness across the full flight envelope.

• Perform trajectory design, optimization, and trade studies for hypersonic, missile, launch vehicle, and space systems, balancing performance, range, payload, thermal, and operational constraints.

• Develop low/med-fidelity simulations and digital engineering models to support concept development, requirements analysis, mission planning, system design, verification, and test activities.

• Conduct prelimimary aerodynamic, propulsion, mass properties, and environmental sensitivity analyses to assess vehicle performance and identify key design drivers and technical risks.

• Perform flight mechanics analyses including stability and control assessments, separation dynamics, staging events, atmospheric flight, reentry, and orbital mission operations as applicable.

• Develop and integrate mission-level models within modeling and simulation frameworks, digital engineering environments, and hardware-in-the-loop or software-in-the-loop test architectures.

• Support flight test planning, pre-flight predictions, post-flight reconstruction, and data analysis activities to validate models and improve system performance.

• Collaborate across disciplines including aerodynamics, propulsion, thermal, systems engineering, software, and mission analysis teams to translate requirements into executable vehicle designs.

• Support technical proposals, customer engagements, concept studies, and strategic growth initiatives related to advanced aerospace, missile defense, hypersonic, and space systems.

• Present technical results, trade studies, and recommendations to internal leadership, customers, and stakeholders through briefings, reports, and design reviews.

Basic Qualifications.  

• Bachelor's Degree in Aerospace Engineering, Mechanical Engineering, Physics, Applied Mathematics, or related engineering discipline from an ABET-accredited institution.

• Minimum 2-4 years of experience in flight dynamics, trajectory analysis, mission design, guidance and control, modeling and simulation, or related aerospace engineering disciplines.

• Demonstrated experience developing and analyzing tools in support of 3DOF and/or 6DOF vehicle simulations.

• Basic understanding of flight mechanics, orbital mechanics, trajectory optimization, vehicle stability and control, mass properties, and aerospace vehicle performance.

• Demonstrated capability establishing data pipeline transformations, executing batch simulation runs, or debugging continuous integration test sequences.

• Ability to work effectively within cross-functional engineering teams in a fast-paced development environment.

• Experience supporting technical proposals, customer interactions, and engineering reviews.

• Active Secret security clearance with the ability to obtain and maintain TS, as required.

Preferred Qualifications.

• Bachelors or Master's Degree in Aerospace Engineering, Systems engineering, Mechanical Engineering, Physics, Applied Mathematics, or related discipline.

• Experience supporting hypersonic systems, missile systems, space vehicles, launch vehicles, reentry vehicles, or advanced weapons programs.

• Experience creating automated device tracking architectures, signal capture setups, or localized RF / wireless detection configurations within secured engineering environments.

• Hands-on experience configuring hardware interfaces, firmware execution (e.g., microcontrollers, embedded single-board computers), or mechanical prototyping layouts.

• Familiarity with collaborative design suites, parameter manipulation, and distributed configuration tooling (such as Onshape, Fusion 360, or Solid Edge).

• Background supporting complex tactical defense systems, global missile defense simulation suites, or precise long-range missile performance studies.

• Passion for KSP.

• Active TS Clearance

If you're looking for comfort, keep scrolling. At Leidos, we outthink, outbuild, and outpace the status quo — because the mission demands it. We're not hiring followers. We're recruiting the ones who disrupt, provoke, and refuse to fail. Step 10 is ancient history. We're already at step 30 — and moving faster than anyone else dares.
