Job Summary

Join Anduril’s TRS Simulation team to deepen fidelity across a multi-physics simulation framework. You will identify where simulated models diverge from real-world data, integrate higher-fidelity subsystems, optimize performance, and validate fidelity with data from real flight campaigns. Senior engineers will shape technical direction, mentor peers, and drive cross-team fidelity strategy.

Location: Seattle

Workplace: Onsite

Employment Type: Full time

Job Function: Software Engineering

Key Responsibilities

•Analyze simulated subsystems within the framework to identify where system-level behavior diverges from real-world data, quantifying gaps and their downstream impact on simulation trustworthiness.
•Partner with functional engineering teams (flight dynamics, perception, guidance, comms) who own subsystem models to understand requirements, integrate their higher-fidelity models into the simulation framework, and validate the integration through statistical analysis.
•Engineer framework-level solutions that enable higher-fidelity models to run efficiently, addressing performance constraints, timing coordination, and numerical integration concerns.
•Build and maintain validation tooling and benchmarks that make fidelity measurable: automated comparison against real-world data, regression detection, and acceptance threshold enforcement.
•Design and run Monte Carlo validation campaigns to verify that fidelity improvements hold across parameter sweeps and edge cases, not just nominal conditions.

Pay and Benefits

Salary: USD 166,000 - 220,000 annually

Perks:Health InsuranceRetirementCommuter Benefits

Key Requirements

•Bachelor's degree in Computer Science, Engineering, Physics, Mathematics, or a related field.
•3+ years of professional software engineering experience with a systems language (C++, Rust) and an analysis/scripting language (Python, MATLAB).
•Experience with performance analysis and optimization of complex software systems (profiling, bottleneck identification, latency reduction, computational efficiency).
•Numerical and scientific computing concepts (integration methods, statistical analysis).
•Ability to take deep ownership of a system end-to-end: understand it, identify problems, design solutions, implement them, and validate results with data.
