Space Simulation Engineer

Functional Focus: High-Performance Computing, Numerical Methods, and Physics Simulation

• Simulation Engine Development: Write high-performance C++ code for adaptive-step numerical integration of physical systems, handling multiple perturbation/force models.
• Numerical Accuracy & Stability: Implement quaternion-based rotational dynamics and coordinate frame transformations, ensuring zero memory leaks when integrating third-party C/C++ scientific libraries.
• Shared-Memory Optimization: Design cache-friendly memory structures and multi-threaded execution models that avoid race conditions and false sharing across compute cores.
• Parallel Compute Strategy: Evaluate and implement intra-job CPU parallelism strategies — serial, shared-memory (e.g. OpenMP), or message-passing (e.g. MPI) —appropriate to workload scale.
• State Estimation: Implement Kalman-filter-based state estimation that fuses multiple sensor measurements — prediction, innovation, Jacobian assembly, and correction.

Requirements

Mandatory:

• C++ (modern, 11/14/17+)
• Adaptive-step ODE/numerical integration, linear algebra
• Multi-threading (std::thread, thread pools), race-condition/false-sharing avoidance
• Manual memory management, leak-free integration with third-party C/C++ libraries
• Quaternion/rotation math, coordinate frame transforms
• CMake, unit testing (GoogleTest or similar)
• Python (for tooling/scripting/testing)
• Kalman/Bayesian filtering theory
• Attitude/rigid-body dynamics background
• Astrodynamics / orbital mechanics fundamentals
• TLE (Two-Line Element) format familiarity

Optional:

• OpenMP, MPI/OpenMPI
• Valgrind, AddressSanitizer, profilers (perf, VTune)
• CI pipelines for C++, cross-platform builds
