About the Job

Requirements

Proficiency in modern C++ (C++11/14/17 or later).
Experience with adaptive-step ordinary differential equation or numerical integration and linear algebra.
Experience with multithreading using std::thread or thread pools, including avoiding race conditions and false sharing.
Experience with manual memory management and leak-free integration with third-party C/C++ libraries.
Knowledge of quaternion and rotation mathematics and coordinate-frame transformations.
Experience with CMake and unit testing using GoogleTest or a similar framework.
Proficiency in Python for tooling, scripting, and testing.
Knowledge of Kalman or Bayesian filtering theory.
Background in attitude and rigid-body dynamics.
Knowledge of astrodynamics and orbital mechanics fundamentals.
Familiarity with the Two-Line Element (TLE) format.

Responsibilities

Write high-performance C++ code for adaptive-step numerical integration of physical systems, handling multiple perturbation and force models.
Implement quaternion-based rotational dynamics and coordinate-frame transformations, ensuring zero memory leaks when integrating third-party C/C++ scientific libraries.
Design cache-friendly memory structures and multithreaded execution models that avoid race conditions and false sharing across compute cores.
Evaluate and implement intra-job CPU parallelism strategies, including serial, shared-memory (such as OpenMP), or message-passing (such as MPI), as appropriate to workload scale.
Implement Kalman-filter-based state estimation that fuses multiple sensor measurements, including prediction, innovation, Jacobian assembly, and correction.

Desired Qualifications

Experience with OpenMP or MPI/OpenMPI.
Experience with Valgrind, AddressSanitizer, or profilers such as perf and VTune.
Experience with C++ continuous-integration pipelines and cross-platform builds.

About the Company

Astrome Technologies

High-capacity SDN-based wireless backhaul

Astrome Technologies specializes in wireless telecom solutions to ease network congestion and improve 5G backhaul for network operators. Its flagship product, GigaMesh, delivers up to 80 Gbps per cell tower and enables rapid SDN deployment without fiber infrastructure. The system uses remotely reconfigurable software-defined capacity, electronically steered links for quick alignment, and fine pencil beams with encryption options for secure, reliable connections. Compared with competitors, Astrome delivers much higher per-tower capacity, avoids expensive fiber by using wireless links, and reduces operational costs through remote, software-driven reconfiguration and faster deployment. The company's goal is to help telecom operators expand network capacity and reach—especially in urban and rural areas—by providing scalable, high-capacity, cost-effective wireless backhaul solutions that alleviate congestion.
