Software Engineer - Simulation Fidelity

About this role

Anduril Industries seeks a Software Engineer to own simulation fidelity for autonomous military systems, identifying where simulated behavior diverges from real-world performance and engineering solutions that improve model accuracy across the simulation framework. You'll partner with functional teams to integrate higher-fidelity subsystem models, build validation tooling, and run Monte Carlo campaigns to ensure simulations are trustworthy before autonomous systems deploy operationally.

What you'll do

• Analyze simulated subsystems to identify discrepancies from real-world behavior and quantify their impact on simulation trustworthiness
• Collaborate with functional engineering teams to integrate higher-fidelity models and validate them through statistical analysis
• Engineer framework solutions addressing performance constraints, timing coordination, and numerical integration for complex multi-physics systems
• Build and maintain validation tooling, benchmarks, and automated comparison systems against real-world data
• Design and execute Monte Carlo validation campaigns across parameter sweeps and edge cases
• Mentor engineers and drive cross-cutting fidelity strategy at senior level

What they're looking for

• C++ or Rust systems programming
• Python or MATLAB for analysis and scripting
• Performance analysis and optimization
• Multi-physics simulation and numerical methods
• Statistical analysis and validation methodologies
• Software-in-the-loop (SITL) and real-time simulation environments
• Domain knowledge in sensors, flight dynamics, navigation, or autonomy
• Monte Carlo simulation design
