ReOrbit is looking for a 5G NTN LEO Satellite Payload Engineer to join our team and contribute to the development of next-generation satellite communication payloads supporting 5G New Radio (NR) Non-Terrestrial Network (NTN) services. This is an exciting prospect to work on innovative satellite communication systems that enable seamless integration between satellite and terrestrial mobile networks, pushing forward the boundaries of space-based connectivity.
As our 5G NTN LEO Satellite Payload Engineer, you will contribute to the end-to-end architecture, design, analysis, and validation of communication payloads for Low Earth Orbit (LEO) satellite systems. You will work across 3GPP NTN standards, RF and digital payload design, link budget analysis, waveform and signal processing, system-level performance analysis, and payload verification. We are looking for someone who combines a strong understanding of 5G NR physical-layer technologies with practical satellite communications engineering experience and a system-level perspective. The ideal candidate is analytical, hands-on,



and comfortable collaborating across multidisciplinary teams to solve complex engineering challenges.
It's an exciting chance to join a dynamic start-up, with the opportunity to make a real impact, to reach our goal of pushing the boundaries of space data transfer.
This job can be based in our headquarter in Helsinki, Finland or Bengaluru, India.
Responsibilities
• Define and develop communication payload architectures for 5G NR NTN-enabled LEO satellite systems, translating mission and service requirements into payload specifications, performance budgets, and subsystem requirements.

• Evaluate transparent (bent-pipe) and regenerative payload architectures, considering their impact on protocol processing, latency, system complexity, and overall performance.

• Develop payload functional architectures covering RF front-ends, frequency conversion, digital processing, channelisation, switching,
