About the role:

We are looking for a Wireless Communications Systems Developer to join our software-defined radio team. The ideal candidate has strong experience in embedded software development, debugging complex systems, and integrating hardware and software components, with a solid understanding of the system as a whole. 

This role is suited to someone who is passionate, highly resourceful, autonomous, and proactive—someone who can investigate complex problems, quickly learn new components, and work across different parts of a wireless communication system, from signal processing to protocols and overall system behavior. 

Our team develops high-performance solutions on SDR platforms and Octasic’s proprietary multi-core signal processors. The role covers embedded software, wireless protocols, system integration, validation, and intelligent development automation, including the use of AI tools, agentic programming, and, where relevant, AI/ML approaches. 

What you'll do:

• Develop, integrate, and maintain embedded software for wireless communication systems on SDR platforms and multi-core SoCs;
• Contribute to features spanning multiple system components: signal processing, protocol layers, software integration, and overall behavior;
• Diagnose and resolve complex issues related to real-time performance, interoperability, stability, and cross-component integration;
• Design and validate C/C++ and Python code in an environment focused on quality, performance, and maintainability;
• Develop or improve automation tools for testing, debugging, analysis, and technical investigation;
• Leverage AI tools, agentic programming, and, where relevant, AI/ML techniques to support development, technical analysis, and automation;
• Participate in the analysis, detection, and characterization of wireless signals;
• Collaborate with validation, integration, architecture, and product teams, and maintain technical documentation.

Qualifications:

• Bachelor’s degree in electrical engineering, computer engineering, computer science, or a related field;
• 5 to 10 years of experience in embedded software, wireless communications, signal processing, or a related field;
• Good understanding of embedded systems, DSPs, multi-core environments, and real-time constraints;
• Hands-on experience in software development, advanced debugging, and integration of complex systems;
• Strong proficiency in C/C++ and good knowledge of Python;
• Ability to investigate complex problems, connect multiple system components, and understand their interactions;
• A passionate, autonomous, resourceful, structured, and proactive profile with a strong learning mindset;
• Understanding of interactions between PHY, MAC, and upper layers of the protocol stack;
• Strong English communication skills; French is an asset.

Assets:

• Experience with wireless protocols and upper radio-stack layers: MAC, RLC, PDCP, RRC, NAS mobility, QoS, and radio control;
• Good understanding of interactions between real-time functions, protocols, and control mechanisms;
• Experience with different wireless technologies: cellular (LTE / 5G NR), Wi‑Fi, Bluetooth, IoT, FR2/mmWave, and other radio-spectrum signals;
• Experience with RF equipment which can analyze / generate RF signal;
• Experience in wireless signal analysis, recognition, or characterization;
• Awareness of robustness, reliability, and secure design considerations in wireless communication systems;
• Experience with SDR systems, RF, measurement/validation tools, and MATLAB;
• Experience with AI tools, agentic programming, or AI/ML approaches applied to development, debugging, or technical analysis.
