About Remos Space
Remos Space is at the forefront of satellite communications, transforming how ground operations are built and scaled. Our software-defined ground stations and modems enable flexible, cost-effective, and high-performance satellite communications for the new space economy.
We are a deep-tech company operating at the intersection of RF, signal processing, and software—and we’re looking for engineers who want to push the boundaries of what’s possible.
The Role
We are looking for a Software Engineer specializing in Signal Processing and SDR to design and optimize advanced software-defined radio solutions for satellite communications.
You will work on real-world systems involving high-performance DSP, modulation/demodulation, and communication protocols—contributing directly to deployed ground station products.
Key Responsibilities
Develop real-time DSP algorithms for demodulation, synchronization, error correction, and spectrum analysis
Build and maintain high-performance SDR applications using C++ and Python
Design scalable, maintainable architectures using modern software design principles
Leverage modern C++ (C++17/20/23) for performance-critical systems
Optimize signal processing pipelines using Intel IPP and CPU intrinsics
Design and implement advanced modulation schemes, including:
Suppressed carrier: BPSK, QPSK, OQPSK, SOQPSK, 8PSK
Residual carrier: PCM/PM, PCM/PSK/PM
Implement and integrate CCSDS-compliant communication chains, including:
Telemetry (TM): CADU processing, Viterbi, Reed-Solomon, LDPC, Turbo
Telecommand (TC): BCH, LDPC, CLTU encoding/decoding
Develop robust solutions for reliable communication in noisy RF environments
Must-Have Requirements
Hands-on experience with SDR hardware (e.g., USRP or similar platforms)
Strong foundation in digital signal processing (filtering, FFTs, synchronization, adaptive algorithms)
Solid understanding of modulation and demodulation techniques
Proficiency in C++ and Python for high-performance systems
Experience with modern software architecture and design patterns
Knowledge of satellite communication standards (e.g., CCSDS, DVB-S2X)
Experience with FEC and channel coding (Viterbi, Reed-Solomon, LDPC, Turbo, BCH, CADU, CLTU)
Nice to Have
Experience with FPGA development (VHDL/Verilog, Vivado, Quartus)
Exposure to AI/ML in signal processing or spectrum analysis
Deeper familiarity with CCSDS standards such as:
Virtual Channels (VC, MAPs)
Space Link Extension (SLE)
CFDP (File Delivery Protocol)
Why Join Remos Space?
Work on cutting-edge satellite communication systems deployed in real missions
Join a highly technical, ambitious team solving complex RF and space challenges
Have real ownership and impact in a fast-growing deep-tech company
Grow your expertise at the intersection of software, RF, and space systems
