Simulation Software Engineer

Simulation Software Engineer

OQ Technology is looking for a Simulation Software Engineer to support the design, development, and evaluation of next-generation satellite communication systems, with a focus on software-based system simulation, modeling, and performance analysis.

The role involves system-level modeling, simulator and testbed development, and large-scale performance evaluation of satellite networks, supporting OQ Technology's product roadmap and R&D activities in LEO/VLEO satellite communications.

This is a hands-on engineering role with a strong emphasis on software development, combined with system engineering and standards-aware modeling.
