Job summary

Blue Origin in Seattle is seeking an experienced engineer to join the Advanced Concepts and Enterprise Engineering (ACE) team. You will develop physics-based simulation models and rapid Newton dynamic analyses to inform architecture trades and verification strategies for spaceflight mobility systems.

You will build rover mobility studies in Isaac Sim, implement plant and actuator models, and drive model credibility with hardware data.

Qualifications

• 8+ years developing physics-based simulation and dynamic models for high-reliability systems.
• Strong dynamics and multibody modeling fundamentals.
• Experience with simulation framework development and automated testing.
• Familiarity with control system concepts for closed-loop simulations.
• Experience with NVIDIA Isaac Sim for mobility/vehicle simulations.
• Correlating models to hardware test data and applying CI, automated tests.

Responsibilities

• Rapidly stand up and iterate Newton dynamic models to evaluate concepts and envelopes.
• Build rover mobility studies in Isaac Sim (terrain, slope, obstacles) to inform requirements.
• Develop terra mechanics approaches for fidelity vs trades.
• Support control architecture and actuator concept trades with simulation data.
• Produce technical roadmaps: model maturation, test-to-model correlation, phased verification.
• Generate synthetic data to support machine-learning training.
• Mature Isaac Sim + Newton models into verification-grade assets with CM, logging, metrics.
• Correlate models to hardware/test data; drive system identification and parameter updates.
• Implement plant models, actuator dynamics, sensor models, and environment interactions in simulation frameworks.
• Define simulation verification artifacts (test cases, coverage, acceptance criteria).
• Support debugging and anomaly resolution from lab to testing via simulation replay.
• Mentor junior engineers and promote best practices in software quality.
