About the Job

Requirements

  • A Bachelor's degree in Mechanical Engineering or a related STEM field.
  • At least 8 years of relevant experience.
  • U.S. citizenship is required.
  • An active Top Secret clearance at application, current and within scope, renewed or initiated within the last 6 years, is required.
  • Must be able to be successfully screened for Enhanced Security Clearances within a reasonable amount of time determined by the company to meet its business needs.
  • At least 5 years of relevant structural analysis or design experience.
  • At least 3 years of experience performing finite element analysis (FEA) of metallic and/or composite structures using industry tools such as NASTRAN, Abaqus, ANSYS, or similar.
  • At least 3 years of experience generating and checking stress reports, margins of safety, and load paths for primary and secondary structures.
  • At least 3 years of experience performing classical hand calculations, including beam/plate theory, bolted and bonded joints, stability, and fatigue/fracture basics, to complement FEA.
  • At least 3 years of experience interpreting loads and environments, including aerodynamic, thermal, pressure, and inertial loads, and applying them appropriately in structural models.
  • At least 3 years of experience performing air vehicle dynamic structural assessments, including shock and vibration.
  • At least 3 years of experience with systems packaging, sizing, and weight tradeoffs and analysis.
  • At least 5 years of experience with CAD and pre/post-processing tools such as NX, CATIA, Creo, HyperMesh, Femap, or similar.
  • Ability to document technical work clearly and present results to cross-functional teams including structures, aerodynamics, TPS, and systems.
  • Willingness to travel up to 25% of the time.

Responsibilities

  • Define and maintain the overall mechanical layout for the vehicle and major subsystems, including structures, TPS hardware, mechanisms, payload, and avionics packaging.
  • Coordinate mass properties, interfaces, access, and maintainability across the configuration.
  • Oversee creation and release of mechanical designs, 3D models, and drawings in collaboration with the design/drafting team.
  • Ensure interfaces between subsystems are clearly defined, controlled, and compatible across mechanical, thermal, alignment, and envelope considerations.
  • Resolve mechanical integration issues between aerothermal, TPS, structures, GNC, propulsion, and avionics.
  • Flow down system requirements into mechanical requirements, constraints, and design criteria covering environments, loads, clearances, margins, and materials.
  • Work with systems engineering to maintain requirements traceability and define mechanical verification methods through analysis, inspection, and test.
  • Collaborate with manufacturing and operations to ensure designs are producible, testable, and supportable.
  • Support build and integration on the factory floor, including build issues, nonconformance disposition, and redlines.
  • Provide technical direction to mechanical suppliers on requirements, reviews, deviations, and acceptance.
  • Plan and coordinate mechanical engineering work across a small team, including tasking, priorities, and schedules.
  • Review and approve design work products to ensure consistency with program standards and best practices.
  • Mentor junior engineers and foster communication across disciplines and integrated product teams.

Desired Qualifications

  • Experience on hypersonic, high-speed, or reentry vehicle programs, or similarly demanding environments such as missiles, launch vehicles, or spacecraft.
  • Experience with thermal–structural coupling, including applying aerothermal/TPS temperatures in structural models and assessing thermal stresses.
  • Experience with nonlinear analysis, including geometric and/or material nonlinearity, contact, and large deflection.
  • Experience with fatigue and fracture mechanics for mission profiles with significant thermal or dynamic loading.
  • Familiarity with high-temperature materials and TPS-support structures, such as CMCs, high-temperature alloys, and advanced composites.
  • Experience supporting structural tests at component, subassembly, or system level, including test planning, instrumentation input, predicting test response, and correlating models to data.
  • Experience with requirements and verification, including writing structural requirements, defining verification methods, and maintaining traceability.
  • Scripting or automation skills using Python, MATLAB, or similar for model setup, post-processing, and data reduction.
  • Experience working in a configuration-controlled environment with formal design reviews such as PDR/CDR and change management.
  • Knowledge of hypersonic reentry vehicle systems, environments, and typical structural tests and assessments.
  • Knowledge of launch vehicle interfaces and environments.
  • Knowledge of advanced materials and manufacturing processes.

About the Company

Northrop Grumman

Builds stealth bombers, missiles, and satellites

Northrop Grumman builds military aircraft, missiles, rocket motors, satellites, and electronic systems, mostly for the American military and allied governments. It designed the B-2 stealth bomber and built NASA's James Webb Space Telescope, the largest telescope ever sent to space. The company works through four businesses: aircraft, missiles and ammunition, radar and communications systems, and space hardware such as satellites and solid rocket boosters. Most revenue comes from long-term government contracts, many of them classified. Its roots go back to Northrop Aircraft, founded in 1939, and it took its name after buying Grumman in 1994 and is based in Falls Church, Virginia.
