5G DSP Systems Engineer

WHO ARE WE?

Sateliot is a Barcelona-based Startup in the New Space sector, becoming the
first satellite telecommunications operator
that will provide
global and continuous connectivity
to all the elements that will make up the massive Internet of Things
(IoT) universe under the 5G protocol
.

In order to do so, Sateliot is launching a
constellation of last generation nanosatellites
, located at low altitude that act as mobile towers. Sateliot is the perfect complement for large telecommunications companies by providing them with the necessary infrastructure where terrestrial technologies do not arrive.

YOUR MISSION

We are seeking a highly skilled and motivated 5G DSP System Engineer to join our Advanced Communications technology team. This role involves the development and implementation of physical layer algorithms for cutting-edge 5G radio systems. The ideal candidate will be responsible for designing, modelling, and verifying signal processing algorithms with a strong focus on high-performance and real-time requirements.

YOUR MAIN FUNCTIONS

• Design and develop signal processing algorithms for 5G wireless systems with focus on advanced physical layer functions.
• Implement and simulate algorithmic prototypes using MATLAB, ensuring functionality and performance in simulated environments.
• Translate algorithmic models into structured, modular C/C++ code, targeting efficient hardware implementation.
• Collaborate closely with the FPGA design team to ensure seamless integration of the algorithms into FPGA-based platforms via High-Level Synthesis (HLS).
• Perform end-to-end system simulations and contribute to the development of

reference processing chains for 5G use cases.
- Validate and optimize algorithmic performance across a range of channel models and test vectors, ensuring alignment with 3GPP specifications.

REQUIREMENTS

• Master's or Ph.D. degree in Electrical Engineering, Computer Engineering,

Telecommunications, or a related field.
- Proven experience in DSP algorithm design for wireless communication systems, ideally within the 5G NR framework.
- Strong understanding of digital communications theory, including modulation, channel estimation, equalization, and MIMO processing.
- Hands-on experience with MATLAB for algorithm development and simulation.
- Proficiency in structured C/C++ coding, with focus on performance, modularity, and hardware-compatibility.
- Solid foundation in the 5G PHY and Low-PHY layers, with familiarity in signal chain

requirements and standard compliance.
- Experience with version control, code documentation, and unit testing frameworks.

NICE TO HAVE

• Familiarity with High-Level Synthesis (HLS) workflows and constraints for FPGA-based systems.
• Prior exposure to radio transceiver architectures and baseband signal processing

pipelines.
- Experience working in cross-functional teams involving hardware and systems

engineers.
- Good understanding of system-level trade-offs including latency, throughput, and

power constraints.
- Excellent problem-solving skills and analytical thinking.
- Strong communication skills and the ability to work collaboratively in a fast-paced,

innovative environment.
- Passion for continuous learning and staying current with emerging wireless

technologies.
