Tutti i potenziali candidati sono invitati a leggere con attenzione i seguenti dettagli prima di inviare la propria candidatura.
As a leader in satellite communications, we provide global connectivity solutions - connecting businesses, communities, and governments around the world. We can connect you at on land, at sea and in the air. We also deliver broadcast television channels and packages, transmitting vital news reports around the world.
With Eutelsat You’ll Get To:
-
- Pioneer the future of Space Technology
- Bring connectivity to remote frontiers
- Collaborate with customer‑centric experts
- Embrace cultural diversity in our global team
In a dynamic industry where passion drives our teams to make a difference to become the most trusted partner for global satellite connectivity, you will elevate your skills in a stretching, rewarding, and meaningful environment. At Eutelsat, we’re united by inclusion and diversity, striving for gender balance and social responsibility, on Earth and in Space.
Why Eutelsat?
-
- Commitment to Diversity & Inclusion: With colleagues from over 75 countries, we embrace our global DNA and are committed to creating an inclusive workplace. We are proud that one-third of our executive team and 60% of our board are represented by women.
- Ways of Working That Drive Us: As "One Team", we work collaboratively towards shared goals, with customer‑centricity, respect, and inclusivity as our guiding principles.
- Sustainability at Our Core: At Eutelsat, sustainability is more than just a word; it’s woven into our strategy.
We’re dedicated to balancing social, environmental, and economic growth — both on Earth and in space.
- Work‑Life Balance: We offer flexible schedules and hybrid work options to help you balance your personal and professional life. At Eutelsat, we are committed to supporting your well‑being and ensuring you have the flexibility you need to succeed both at work and at home.
We are looking for an experienced modem architect to become Eutelsat's technical authority on the physical layer of our next generation LEO, multi‑orbit and IRIS² user terminals: a Ku and Ka band waveform that must acquire below 0 dB Es/N0, track Doppler excursions of hundreds of kilohertz with slew rates in the tens of kilohertz per second, ride through beam and satellite handovers with an interruption budget of a few tens of milliseconds, and do so within a single digit watt baseband envelope and a cost‑driven silicon budget. The target is a single‑chip modem module in which the programmable PHY, the protocol stack and the host processor functions share one SoC, built from vector compute engines, a RISC‑V control subsystem, hardware accelerators and an on‑chip NPU.
Much of the detailed implementation is carried out with external engineering and silicon partners. Your role is to master that technology to the point of owning it: to hold the requirements,
to model the link independently, to assess and challenge the design choices made on our behalf, and to accept or reject what is delivered on evidence. Knowing the platform hands‑on is part of the job, not a formality, and so is the ability to reproduce a result yourself when a claim needs testing.
This is a founding role, a pioneering one and the design authority liaising directly with the vendors and internal stakeholders. Eutelsat is building its own terminal physical layer competence and this position is where that capability starts: the models, the tooling, the test assets and the working practices are still to be created, in a programme that moves at constellation pace and relies heavily on external partners while the team is assembled. As the capability grows, this role is the natural anchor for the modem architecture group that will be built around it.
What you’ll do
-
- Master the platform hands‑on: SDK and toolchain, micro‑kernel architecture of the PHY, mapping onto signal units, scheduling and synchronisation across units, hardware abstraction layers over the FEC and signal processing engines, DMA fabric, interrupts and inter‑processor communication. You should be able to build, modify, instrument and profile PHY code yourself;
- Own the terminal physical layer requirements and their traceability, from service and constellation constraints down to waveform, timing and modem parameters, and hold the specification stable through the programme;
- Assess and challenge the receive chain design: acquisition strategy and its performance below 0 dB Es/N0, CFO and SFO estimation, timing recovery, carrier phase tracking under composite LO and converter phase noise, ch
