Job Summary

With our groundbreaking satellite 5G constellation OQ Technology is a global leader in IoT connectivity and next-generation satellite communication services. As a venture-backed company with a proven track record of satellite launches we are the first in the world to integrate cellular 5G with satellites enabling seamless connectivity for devices in remote and underserved regions.

Our technology supports transformative applications across industries such as Oil & Gas Maritime Industry 4.0 and Transport extending reliable connectivity through Non-Terrestrial Networks (NTN).

To support the continued development of our advanced telecommunications platform we are looking for a Telecom R&D Engineer - NTN to join our this role you will contribute to the development and optimization of 3GPP-based protocol stacks and NTN adaptations for NB-IoT LTE and 5G NR technologies helping bring cutting-edge satellite connectivity solutions from research to real-world deployment.

Tasks

Contribute to the research development and adaptation of L1/L2/L3 protocol stack components for Non-Terrestrial Networks (NTN) supporting NB-IoT LTE and 5G NR technologies.
Participate in the full R&D lifecycle including system design implementation integration testing and performance optimization.
Analyze troubleshoot and enhance protocol stack behavior across multiple layers including PHY MAC RLC PDCP RRC and NAS.
Investigate and implement NTN-specific adaptations required for satellite communications including aspects related to propagation delay Doppler effects and timing synchronization.
Design and execute testing and validation procedures including unit testing system integration testing and performance benchmarking.
Contribute to software integration and deployment workflows including continuous integration and version control practices.
Stay up to date with 3GPP standardization developments (e.g. NTN features in Releases 17/18/19) and contribute to translating standards into practical implementations.
Collaborate with cross-functional teams including RF FPGA satellite systems and platform engineering to integrate telecom stacks with hardware and system components.
Support system-level analysis and debugging including log analysis KPI evaluation and protocol trace inspection.

Requirements

An academic degree in Telecommunications Engineering Electrical Engineering Computer Science or a related field.
5 years of experience in telecom R&D preferably working with 3GPP-based wireless systems.
Solid understanding of 3GPP protocol architecture and procedures in NB-IoT LTE or 5G NR.
Strong programming skills in C/C with additional scripting experience in Python for automation and analysis.
Experience working in Linux/Unix environments with standard development and debugging tools.
Familiarity with software development workflows including version control (e.g. Git) and CI/CD practices.
Strong analytical and troubleshooting skills with the ability to diagnose complex system-level issues.
Good communication and collaboration skills in a multidisciplinary engineering environment.
Proficiency in spoken and written English.
IMPORTANT: Candidate must already reside in Europe or hold a valid European residence permit.

Preferred skills and experience

Hands-on experience with 3GPP wireless systems particularly NB-IoT LTE or 5G NR implementations.
Experience working with NTN architectures and protocol adaptations defined in 3GPP specifications.
Practical experience analyzing and modifying protocol stack components across L1/L2/L3 layers (PHY MAC RLC PDCP RRC NAS).
Familiarity with core network signalling protocols such as S1AP NGAP and GTP-C/U.
Experience working with software-defined radio platforms (e.g. USRP) or open telecom stacks such as srsRAN and OpenAirInterface or Open5GS and free5GC.
Knowledge of O-RAN architecture and functional split concepts.
Familiarity with Small Cell Forum (SCF) interfaces including FAPI/nFAPI.
Background in embedded or real-time software development particularly on ARM-based or heterogeneous platforms.
Experience with protocol debugging KPI analysis and system performance optimization in wireless communication systems.

Benefits

Enjoy a 50% income tax exemption on your salary - an exceptional incentive for top talent relocating to Luxembourg subject to eligibility conditions.
Hybrid working environment.
Opportunity to work on flagship EU space mission projects.
A dynamic high-growth environment with career development opportunities.
Regular company events and team activities.
