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.
Key Responsibilities:
-
Software Engineering & Tooling • Develop robust simulation pipelines, including configuration handling, logging, data storage, and result post-processing. • Apply software engineering best practices: version control, code reviews, documentation, and testing. • Optimize simulation performance and scalability where required. • Contribute to the evolution of internal simulation frameworks and tools.
-
Simulation & Testbed Development • Design and implement modular system-level simulators for satellite communication systems. • Develop software models for Satellite payload and user links, telcom protocol abstractions and User traffic and mobility models • Integrate models across space, ground, and user segments.
-
Performance Evaluation & Analysis • Execute large-scale simulations and analyze system performance. • Support validation and benchmarking of new technologies against baseline systems.
-
Technical Documentation & Reviews • Produce clear technical documentation for internal and external stakeholders. • Contribute to project planning and technical reporting.
Key Qualifications:
- MSc or PhD in Telecommunications, Wireless Communications, Aerospace Engineering, or a related field.
- Strong software development skills with experience in complex technical codebases.
- Proficiency in Python and/or MATLAB for scientific computing and simulation. C++ will be an asset.
- Experience with object-oriented and modular software design.
- Experience building or maintaining simulation frameworks, numerical models, or analytical tools.
- Ability to translate high-level system concepts into executable software models.
- Prior involvement in European, ESA, or collaborative R&D projects.
- Basic understanding of satellite communication systems (LEO/VLEO preferred).
- Familiarity with 5G NR and/or NB-IoT, and awareness of NTN adaptations.
- Exposure to system-level requirements and KPIs (throughput, latency, availability, coverage).
- Familiarity with RRM, handover, beam management, or routing at a conceptual or modeling level.
- Experience with open-source simulators or telecom stacks (e.g., ns-3, OAI, srsRAN).
- Proficiency in spoken and written English.
- IMPORTANT: Already a resident in Europe or has European visa
Benefits:
- Enjoy a 50% income tax exemption on your salary—an exceptional incentive for top talent relocating to Luxembourg, subject to eligibility conditions.
