Senior Structural and Thermal Engineer - Optical Systems - TeraWave

Application close date:

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We're working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight!

As a Structural & Thermal Engineer focused on STOP analysis, you will serve as the analytical backbone, ensuring our optical systems achieve peak performance from launch through on-orbit operations. You will own the integrated Structural, Thermal, and Optical Performance (STOP) analysis, and your models will directly guide critical opto-mechanical design decisions.

The Mission:

You will be the engineer who answers the critical question: "Will this system meet its optical performance requirements in space?" Through high-fidelity modeling, simulation, and rigorous uncertainty quantification, your analyses will provide the foundation of confidence that our designs are robust against the challenges of launch and the space environment.

Special Mentions:

• Relocation assistance may be available for this position

• Travel expectations:
  Occasional travel may be required for test campaigns and design reviews

Responsibilities include but are not limited to:

Integrated STOP Analysis

• Perform coupled STOP analysis by integrating your structural and thermal predictions with the optical design model (via ray-tracing or sensitivity matrices)

• Derive, allocate, and close optical performance budgets (e.g., alignment, WFE) in collaboration with optical and mechanical engineers

• Bound system sensitivities to environmental and structural inputs (temperature gradients, launch loads) and propose effective design mitigations

Structural Modeling & Jitter Analysis

• Build and maintain high-fidelity Finite Element (FEA) models to analyze modal response, random vibration (PSD), shock, and quasi-static loads

• Analyze and mitigate the effects of gravity release and mount preloads on optical alignment and surface figure

• Quantify structural stiffness and jitter transfer functions to ensure fine-pointing stability and performance

Thermal Modeling & Control

• Develop detailed thermal models to simulate radiation, conduction, and active thermal control systems (heaters, straps, radiators)

• Manage thermal dissipation and ensure optical stability across all operational and survival modes, including eclipse transitions and slews

• Translate thermoelastic distortions from your models into quantified impacts on optical performance, such as focus shifts and alignment drift

Model Validation & Test Correlation

• Define a comprehensive model validation plan, specifying instrumentation requirements (accelerometers, thermocouples, strain gauges) for environmental testing

• Correlate analytical models with thermal-vacuum (TVAC) and vibration test data, iterating as needed to improve predictive accuracy

• Develop and present the definitive evidence package for system feasibility, including model pedigree, uncertainty analysis, and sensitivity studies

Minimum Qualifications:

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a related field with 7+ years of relevant experience (M.S./Ph.D. preferred)

• Expertise in FEA for precision space structures, with proven experience in modal/dynamic analysis, random vibration, and thermoelastic distortion

• Deep understanding of passive and active thermal control systems and analysis for space applications

• Strong skills in uncertainty quantification, including probabilistic analysis, Monte Carlo methods, and sensitivity studies

• Proficiency with relevant analysis software (FEA: Nastran, Ansys, or Abaqus; Thermal: Thermal Desktop, SINDA/FLUINT, or similar)

Preferred Qualifications:

• Mastery of coupling…
