Job description

Why Castelion, Why Now

Castelion is moving incredibly fast to develop and deliver advanced defense systems at a time when execution matters more than ever. We believe focus and technical excellence are decisive advantages - and we are building a team that can deliver real capability, not just concepts.

This is a rare opportunity to join at an early stage, where your work will directly shape critical systems, influence major technical decisions, and have immediate, real-world impact.

Structural Analysis Engineer

We're looking for a Structural Analysis Engineer to help design and validate next-generation hypersonic defense systems. You'll work in a fast-moving startup environment where analysis directly informs design decisions, hardware builds, and flight readiness. This role offers high ownership, close collaboration with design and test teams, and the opportunity to see your work rapidly turn into flying hardware.

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 closely 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 your work
  • Communicate technical content in an efficient and effective manner to partner teams

Basic Qualifications

  • 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.
  • Comfortable working in ambiguous, rapidly evolving technical environments.

Preferred Skills and Experience

  • 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 (e.g., FAA, NASA, MIL).
  • Scripting or programming experience (Python, MATLAB) to automate analysis workflows.
  • Experience supporting hardware testing or flight operations

Other Duties

Please note this job description is not designed to cover or contain a comprehensive listing of activities, duties or responsibilities that are required of the employee for this job. Duties, responsibilities and activities may change at any time with or without notice.

Benefits And Perks

All full-time employees are granted meaningful long-term equity, sharing in the company's significant growth trajectory. We offer four (4) weeks of paid time off, ten (10) company-paid holidays, and comprehensive health benefits - including 100% employee-covered medical and strong dependent coverage, along with dental and vision plans. We also provide paid parental leave to support growing families, a $100 monthly fitness stipend to promote health and performance, and onsite EV charging for convenience. In addition, employees enjoy perks like catered meals, company-covered food during high-demand periods, and a fully stocked kitchen to stay fueled throughout the day.

While this position does not currently require a U.S government-issued security clearance, it may in the near future. Therefore, the ability to obtain and maintain a U.S. government–issued security clearance is required. U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance.

Affirmative Action/EEO Statement

Employment with Castelion is governed on the basis of competence and qualifications and will not be influenced in any manner by race, color, religion, gender, national origin/ethnicity, veteran status, disability status, age, sexual orientation, gender identity, marital status, mental or physical disability or any other legally protected status.
