Senior Embedded Software Engineer

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 • Develop the Hardware Abstraction Layer (HAL) and low-level C drivers for a next-generation multi-core SOC architecture. • Design and implement Inter-Processor Communication (IPC) mailbox drivers to orchestrate data exchange between Application, Protocol, and Radio cores. • Implement the system-wide power management state machine, managing clock gating and supply assignments for ultra-low power consumption. • Create Board Support Packages (BSPs) and Devicetree definitions to adapt the hardware to Zephyr and FreeRTOS ecosystems. • Collaborate with the architecture team to define memory maps and interrupt routing for a complex multi-core system. • Working directly with hardware teams. • Ensure code compliance with unified code styles and static security analysis requirements. REQUIREMENTS • 5+ years of embedded software development experience with a strong focus on low-level drivers and HAL. • Deep knowledge of ARM Cortex-M architecture and multi-core resource scheduling. • Proficiency in C programming for real-time operating systems, specifically Zephyr and FreeRTOS. • Experience implementing Inter-Processor Communication (IPC) mechanisms (mailboxes, spinlocks, shared memory). • Familiarity with peripheral interfaces such as SPI, QSPI, GPIO, I2C, PWM, and ADC. • Experience working with FPGA emulation platforms or RTL simulation environments for early software bring-up. • Solid understanding of embedded power management, including sleep modes and wake-up sources. • English language proficiency for technical documentation and cross-functional communication. NICE TO HAVE • Experience integrating software with the CMSIS layer. • Previous involvement in developing Software Development Kits (SDKs) for public release. • Familiarity with CMake/Kconfig build systems. WE OFFER • Flexible work schedule; • Private healthcare insurance - LuxMed (extended gold package for parents & kids); • Multisport card; • Workation; • Financial bonuses for significant life events (wedding, birth of a child); • Compensation of professional training: courses, seminars, trainings (it is decided for each person individually if the whole thing or a part of it will be covered); • Author's right (for those who write the code).
