Senior Spectrum Engineer, ITU-R and 3GPP

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.

About the team & this role

Spectrum decides what a satellite network is allowed to do, and for non-terrestrial networks it is being decided right now: in ITU-R, on the way to the World Radiocommunication Conferences, and in 3GPP, where radio-frequency and coexistence requirements are specified. Sateliot is active in both forums, and holding a position there takes continuous presence. As Senior Spectrum Engineer you join the Service, Devices and Standardisation team and lead our spectrum strategy. You are the technical counterpart to our Regulatory department, you represent the company in person before regulators and standards bodies, and you keep our position aligned across radio access technologies.

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 design, for a band plan, for terminal RF, and for interference mitigation on the device.

Bonus if you have

• Satellite direct-to-device, MSS allocations or IMT band work.

• Sharing studies against incumbent services: terrestrial IMT, fixed, FSS and adjacent services.

• Standing in the regulatory community: named delegate, rapporteur, or contributions on record.

• Exposure to the Spanish administration, CEPT/CPG or APT processes.

Additional requirements

• Willingness to travel internationally several times a year: ITU-R and 3GPP meetings are held in person, and continuous attendance is part of the role.

• Hybrid work with regular on-site presence at our Barcelona HQ.

• Working proficiency in English, the language of both the regulatory and the standards arena.

How we work

We lead with humility, move fast, and take ownership. We collaborate without ego and measure ourselves by real impact, not titles or hierarchy. We hire people who already live these values.

What we offer

• Real impact on one of Europe’s most ambitious space projects.

• Growth: we cover 50% of courses or master’s degrees (up to 5% of your salary), plus Spanish and Catalan classes.

• Health & balance: 50% on private health insurance and Urban Sports Club, a flexible schedule, and hybrid work, we focus on results, not hours.

• Flexible Compensation: flexible compensation through Cobee (meal, transport, kindergarten).

• A truly global team: 20+ nationalities building something genuinely new - and genuinely nice to work with. Great vibes, real teamwork.

• A real welcome: a dedicated buddy from day one.

• Life outside work: we organize leisure and sports activities both during and outside working hours - because great teams connect beyond the screen.

• Catering: if you don't have time to cook, we partner with a catering company so a freshmeal is sorted, no need to think about it.

• Parking: on-site parking at the office, with Sateliot covering 50% of the cost - plus free bike parking if you prefer to pedal in.
