About The Team & This Role
Sateliot is a Barcelona-based satellite company with one goal: connect everything, everywhere. Founded in 2018, we've built the first satellite constellation that lets standard commercial devices communicate directly from space. Our technology bridges the gaps that terrestrial networks will never reach, bringing affordable and secure connectivity to industries, governments, and communities across the planet.

What you'll do

Own the technical position behind our spectrum strategy: candidate bands, spectrum sharing, and compatibility with other radio technologies worldwide.

Take part in the ITU-R work and shape it: band selection under the WRC-27 agenda, and the future agenda items that will define the next cycle, including direct-to-device allocations above 3 GHz.

Be our delegate in the 3GPP working groups: RAN4 for coexistence between terrestrial and non-terrestrial bands and for RF requirements, and RAN1 for multi-RAT spectrum sharing.

Lead our spectrum analysis: sharing and interference studies,



power flux density (PFD) and equivalent power flux density (EPFD) limits, and link budget implications.

Turn regulation into engineering. Translate allocation constraints into requirements for our radio access roadmap, our band plans and our device ecosystem, and act as Sateliot's delegate before regulatory bodies and with our external advisors.

What you bring

At least ten years, and typically closer to fifteen, working on spectrum for mobile or satellite systems, with real ownership of a position defended before a regulator or a standards body.

Direct experience of ITU-R or WRC preparation — study groups and working parties, CEPT, APT or a national administration — with a working understanding of how a proposal becomes an agenda item.

Hands-on RF and coexistence engineering in 3GPP RAN4 or RAN1.

The ability to translate a regulatory constraint into device requirements: what it means for a radio desi
