Pay & benefits

What you'll get

  • 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.

Requirements

What we're looking for

  • Complete ownership of test and validation for cellular radio access, with test specifications you wrote yourself and saw through review with developers, operators or certification partners.

  • The ability to derive a test specification from a 3GPP specification, and to set acceptance criteria that catch real defects rather than produce green dashboards.

  • Ownership of the test system itself: harness and automation design, what belongs in CI and what belongs on the bench, and a regression suite that stays affordable as the stack grows.

  • Deep lab practice - protocol analysis, SDR benches, channel emulation, load and stability campaigns - and the root-cause discipline to say where a failure actually lives: stack, device or link.

  • NB-IoT, LTE or 5G NR validation experience with a commercial-grade stack.

Nice to have

  • Validation and testing experience of non-terrestrial networks.

  • Conformance and certification frameworks: 3GPP RAN5, GCF or operator acceptance.

  • Test automation and CI/CD for radio software.

  • Having built a test capability or organisation from scratch.

The 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 test specification for our RAN components: what gets tested, against which acceptance criteria, and what constitutes proof that a feature behaves as designed.

  • Build the test pyramid and keep it honest: L1 and RF performance and conformance, protocol stack, load, capacity and stability, interoperability and field.

  • Be the independent counterpart to the stack developers - challenge designs early, and validate what they deliver without having a stake in it.

  • Turn our lab into a validation capability: SDR benches, channel emulation, our own test terminal, and automated regression running in CI.

  • Own the validation of supplier deliveries and the evidence behind what we commit outside the department, working with our field testing teams on the campaigns that close the loop.

How you'll work

  • We would prefer you based in Barcelona, where the labs and most of the team sit, and the role is hands-on with the benches. For the right person the location is negotiable, India included, with regular time on site.

  • Occasional travel for field test campaigns.

  • Working proficiency in English.

How we work

In their own words

About the company & team

Sateliot brings standard cellular connectivity from space and develops key parts of its radio access technology in-house. That makes validation a discipline of its own: whoever proves that a radio stack does what it is supposed to do should not be the person who wrote it. As Senior RAN Test Architect you own how our radio access components get validated - what must be tested, to which criteria, and what counts as evidence - across the NB-IoT and 5G NR non-terrestrial domains, and you are deliberately independent from the engineers implementing them. This is a senior role for someone who writes test specifications, not only test reports.
