Descrizione del lavoro

Astrome Technologies in Bengaluru seeks a seasoned C++ developer to lead high-performance simulation work for physics-based systems.

You will implement adaptive-step numerical integration, quaternion-based dynamics, and multithreaded software with careful memory management. The role requires strong knowledge of Kalman filtering, attitude dynamics, astrodynamics, and TLE handling, plus CMake and GoogleTest. Python tooling and cross-platform builds are valued, with optional MPI/OpenMP for scaling.

Competenze

• Proficient in modern C++ (11/14/17+).
• Experience with adaptive-step numerical integration and ODEs.
• Strong knowledge of multithreading and race-condition avoidance.
• Manual memory management with third-party libraries.
• Familiarity with quaternion rotations and coordinate transforms.
• Experience with CMake and unit testing (GoogleTest or similar).
• Python scripting for tooling and testing.
• Background in Kalman/Bayesian filtering.
• Background in attitude/rigid-body dynamics and astrodynamics.
• Familiar with TLE format.

Mansioni

• Write high-performance C++ code for adaptive-step numerical integration of physical systems, handling multiple perturbation/force models.
• Implement quaternion-based rotational dynamics and coordinate frame transformations with zero memory leaks when integrating third-party libraries.
• Design cache-friendly memory structures and multi-threaded execution models avoiding race conditions across compute cores.
• Evaluate and implement intra-job CPU parallelism strategies — serial, OpenMP, or MPI — appropriate to workload scale.
• Implement Kalman-filter-based state estimation fusing multiple sensor measurements: prediction, innovation, Jacobian, correction.

Descrizione del lavoro

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.

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

We offer great career growth, ESOPs, Gratuity, PF and Health Insurance.
