User Terminal Senior Modem Engineer
Be part of a new era in communications, transforming connectivity with Eutelsat – the world’s first GEO-LEO integrated global satellite operator.
La preghiamo di leggere attentamente la panoramica e i requisiti per questa possibilità di lavoro riportati di seguito.
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 a hands-on modem engineer to work side by side with our modem architect on the physical layer of Eutelsat's 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, ride through beam and satellite handovers in tens of milliseconds, and do so within a single digit watt baseband envelope. 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.
Where the architect decides what has to be true, you are the one who finds out whether it is. You will bring the platform up, build the bench and the automation around it, run every measurement campaign, verify what is delivered against golden vectors rather than against the accompanying slides, and chase the discrepancies to their root cause. It is a deeply technical execution role: firmware,
instruments, capture files and cycle counts, every day.
This is a founding role in a capability under construction. The tooling, the test assets and the working practices do not exist yet; you will build them, and they will become the way Eutelsat verifies its own terminals.
What you'll do
- Bring the platform up: toolchains and build environments, boot and firmware images, RISC-V subsystem initialisation, converter, clocking and peripheral configuration, and first signal through the transmit and receive chains;
- Work inside the PHY software: build, modify, port and optimise signal processing micro-kernels, their scheduling across signal units, and the glue code and hardware abstraction layers around the FEC and signal processing engines;
- Build and own the laboratory bench: RF chain, vector signal generators and analysers, channel emulator, GNSS simulator, timing test set, and the switching and calibration around them;
- Automate everything that will be run more than twice: scripted instrument control, unattended campaigns, nightly regression on target, a results store and the reporting that goes with it;
- Execute the acceptance and characterisation campaigns defined with the architect: BER and BLER against Es/N0, acquisition time distributions, Doppler ramp and phase noise sensitivity, handover interruption time, EVM, ACLR and spectral mask, throughput and latency, and timing performance against max|TE|, MTIE, TDEV and holdover masks;
- Verify delivered software bit-exactly against the reference model and its golden vectors, quantify and explain every departure, and keep the regression suite aligned as the platform evolves;
- Instrument and profile the target: IQ capture at
