Senior Embedded Software Developer (Connectivity&Protocols)

ABOUT THE PROJECT

Join a strategic partnership with a global leader in long-range wireless technology to architect the software ecosystem for a next-generation multi-core System-on-Chip (SoC). This engagement goes beyond standard firmware development; you will co-develop a comprehensive developer platform that transforms complex multi-core hardware into an accessible, world-class microcontroller product. By leveraging open-source real-time operating systems like Zephyr and FreeRTOS, and implementing cutting-edge hardware-enforced security frameworks (PSA Level 3, TrustZone, TEE), you will empower the global embedded community to deploy secure, ultra-low-power IoT applications. You will work within a specialized team structure to deliver a modern toolchain centered around Visual Studio Code, ensuring a seamless “edit-build-debug” experience for the next wave of wireless innovation!

YOUR ROLE

• Port and optimize wireless protocol stacks including LoRaWAN, BLE, and 802.15.4 (Thread/Zigbee) for a new multi-core SOC.
• Manage conflict-free access to the RF front-end between concurrent communication stacks.
• Create “Golden Sample” firmware and test modes for atomic radio features (e.g., CAD, ranging, preamble modulation).
• Ensure all radio software complies with regional parameters (FCC/ETSI) such as duty cycle and dwell time.
• Prepare technical data and software hooks required for formal certifications.
• Collaborate with the QA team to validate radio performance using Hardware-in-the-Loop (HiL) infrastructure.

REQUIREMENTS

• Expertise in embedded wireless protocol stacks, particularly LoRa and BLE.
• Proven experience developing resource scheduling logic or arbitration layers for shared hardware resources.
• Strong C programming skills targeting resource-constrained multi-core microcontrollers.
• Experience working with RF front-ends and understanding of physical layer interactions.
• Ability to work with pre-compiled radio binaries and link layer controllers.
• Understanding of real-time constraints and interrupt latency in wireless communications.

NICE TO HAVE

• Experience with Z-Wave or WMBUS protocol stacks.
• Knowledge of Matter protocol integration.
• Background in DSP or physical layer algorithm integration.
• Familiarity with Zephyr RTOS connectivity subsystems.
