About The Position

Castelion is seeking a Structural Analysis Engineer to help design and validate next-generation hypersonic defense systems. The role is in a fast-moving startup environment where analysis informs design decisions, hardware builds, and flight readiness. The engineer will have significant ownership, work closely with design and test teams, and contribute to work that can rapidly become flying hardware. The position involves analyzing aerospace components and assemblies, supporting design iteration, correlating analysis with test data, and contributing to structural testing and qualification. It also requires clear communication and accountability for technical work. The role may require access to classified information or restricted U.S. Government sites, systems, or information, and requires access to applicable export-controlled information without additional export licensing.

Requirements

Bachelor's degree in Aerospace Engineering, Mechanical Engineering, or a related field.
Strong understanding of structural analysis, structural dynamics, and aerospace materials.
Experience with FEA tools such as Abaqus, NASTRAN, or similar solvers.
Comfort working in ambiguous, rapidly evolving technical environments.
Ability to access applicable export-controlled information without additional export licensing being required.

Nice To Haves

Master's degree in Aerospace or Mechanical Engineering.
Experience with launch vehicles, spacecraft, aircraft, UAVs, or propulsion systems.
Knowledge of fatigue, fracture mechanics, buckling, or thermal-structural analysis.
Familiarity with aerospace standards and certification processes, such as FAA, NASA, or MIL.
Scripting or programming experience with Python, MATLAB, or similar tools to automate analysis workflows.
Experience supporting hardware testing or flight operations.

Responsibilities

Perform structural analysis of aerospace components and assemblies under static, dynamic, thermal, and fatigue loading.
Use hand calculations and finite element models to support rapid design iteration.
Work with design engineers to influence geometry, materials, and load paths early in the design process.
Correlate analysis with test data and support structural testing and qualification efforts.
Exemplify technical excellence and be accountable for work.
Communicate technical content efficiently and effectively to partner teams.
