Senior Simulation Engineer Jobs in Seattle, WA (NOW HIRING)

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!

Responsibilities

Consisting of: Early studies / pre-project work (architecture & trades) and Project execution (design, implementation, verification)

- Rapidly stand up and iterate Newton dynamic models (6-DoF / multi-body as appropriate) to evaluate system concepts, margins, sensitivity, and operational envelopes
- Build scenario-based rover mobility studies in Isaac Sim (terrain/slope/obstacle cases, contact/traction behaviors, repeatable test harnesses) to inform requirements and design decisions
- Develop terra mechanics approaches appropriate to fidelity needs (e.g., simplified parametric models for trades vs. higher-fidelity models for risk retirement) and quantify key sensitivities/uncertainties
- Support control architecture and actuator concept trades by providing simulation data products (control margins, sensitivity sweeps, operational envelopes)
- Produce technical roadmaps: model maturation plan, test-to-model correlation plan, and phased verification strategy (MILSILHIL)
- Generate synthetic data to support machine learning training activities

- Mature Isaac Sim + Newton models into verification-grade assets: configuration management, parameter governance, logging/metrics, automated regression scenarios
- Correlate models to component/vehicle/rover test data; drive system identification, parameter updates, and model credibility arguments
- Implement plant models, actuator dynamics, sensor models, and environment interactions within simulation frameworks to enable closed-loop analysis
- Define simulation verification artifacts (test cases, scenario coverage, acceptance criteria, model credibility evidence) for both space vehicle and rover mobility domains
- Support debugging and anomaly resolution from lab to integrated testing (and operations as applicable) through simulation replay and analysis
- Mentor junior engineers and establish best practices for simulation/modeling software quality and reviews

Required Qualifications

- 8+ years developing physics-based simulation and dynamic models for high-reliability systems (aerospace/space, mobility platforms, or similarly mission-critical systems)
- Strong dynamics and multibody modeling fundamentals: rigid/flexible body formulations, contact mechanics, actuator/sensor abstraction, numerical methods
- Demonstrated ability to use simulation to drive decisions across the lifecycle: trade studies design verification
- Experience with simulation framework development (Python, C/C++) plus disciplined configuration management, automated testing, and verification practices
- Familiarity with control system concepts sufficient to implement and evaluate closed-loop simulations (stability, estimation, tuning)

Desired Qualifications

- B.S. (M.S./Ph.D. preferred) in Aerospace, Mechanical, Electrical, Robotics, Computational Science, or related field
- Hands-on experience with NVIDIA Isaac Sim for mobility/vehicle scenario simulation (repeatable environments, terrain/contact interaction workflows, logging/analysis)
- Experience developing/using Newton dynamics models for rapid iteration and verification support (multi-body/6-DoF, actuator/sensor abstractions, Monte Carlo/sensitivity)
- Lunar surface terra mechanics experience (slip/traction modeling, sinkage/rolling resistance, slope handling)
- MIL/SIL/HIL verification experience and automated regression testing of simulation scenarios
- Experience correlating models to hardware test data (system identification, parameter estimation, model credibility frameworks)
- Experience applying modern software practices to modeling/simulation (CI, automated tests, configuration/parameter management)
