Job description

About Elveo Elveo is what happens when two pioneers in direct-to-device (D2D) communications join forces. Elveo brings together a combined 20 years of expertise to close the coverage gap for more than 50 mobile network operators (MNOs) and major distribution partners operating in 60+ countries worldwide. That heritage and our technology powers what we call ‘elevated intelligence’ — a new approach that processes and adapts on orbit, delivering voice and data services straight to mobile users, IoT devices and machines across enterprise, government and humanitarian sectors worldwide. As a team, we’re on a mission to deliver powerful compute and connectivity directly to individuals and objects everywhere on Earth. Join us, and become part of a globally inclusive company that is transforming satellite communications from a niche service to an essential global infrastructure, and democratizing connectivity for billions worldwide. Ready to take the next step? Join us. Job Summary Elveo is developing cellular-based space payloads and seeks a Wireless Engineer to design and implement feeder link modems for Elveo's spacecraft and ground systems. This role involves developing, implementing, and testing DSP and satellite communication protocols. The ideal candidate will have a strong background in wireless communication, signal processing, and software engineering to drive innovation in next-generation satellite-based networks. Core Responsibilities - Design and implement digital signal processing (DSP) algorithms and wireless protocols in the PHY and MAC layers. - Deliver performant and robust production code targeted to software-defined radio (SDR) platforms using single-board computers and/or FPGAs. - Evaluate the performance of algorithms in simulation (e.g., MATLAB, Python) prior to implementation. - Validate performance on target hardware using RF lab equipment like spectrum analyzers and channel simulators, as well as networking tools such as ping and iperf. - Develop test automation frameworks and manage CI/CD pipelines to support unit, integration, and system testing of modems. - Work with cross-functional teams across RF, electronics, and hardware domains to integrate, benchmark, and debug payload software and communications systems. - Debug production issues in conjunction with the operations team to rapidly resolve complex software and hardware anomalies in orbit or on the ground. - Create system performance visualizations to continuously monitor communication links. - Perform link budget analysis for satellite communication links and evaluate the selection of spacecraft radios and ground station products. Qualifications - A Master’s degree or higher in Electrical Engineering, Computer Science, or related field. - Deep understanding of communication theory and signal processing related algorithms design, such as filter design, clock recovery, signal detection, channel estimation and equalization, channel coding. - Strong knowledge of some communications and networking standards, such as DVB-S2/DVB-S2X, and protocols, such as TCP/IP, UDP, ZeroMQ, Ethernet, etc. - Experience with C/C++, Python, MATLAB for algorithm development, modeling, and simulation. - Strong knowledge of software defined radios - SDRs and their implementation. - Proficiency in working with Linux based systems - Hands-on experience in lab testing & characterization. - Experience using test equipment like signal generators, spectrum analyzers, etc. - Experience with implementing DSP algorithms in HDL, such as SystemVerilog, VHDL is a plus. - Knowledge of the 3GPP standards, including LTE and 5G PHY, MAC, and RRC specifications is a plus.
