Embedded Software Engineer

About the Role

We’re looking for a versatile Embedded Software Engineer to join our R&D team and help us bring next‑generation medical and consumer‑electronics products to life. You’ll write firmware that ties together sensors, displays, and multiple wireless stacks—BLE, Wi‑Fi, GSM/LTE, and LoRaWAN—on platforms like nRF52, STM32, and Renesas MCUs.

Key Responsibilities

• Design, develop, and maintain firmware in Embedded C/C++ and Python for microcontrollers (nRF52, STM32, Renesas RA/RE series)
• Integrate and tune a variety of sensors (e.g. environmental, motion, biometric) over I²C, SPI, and UART
• Implement and optimize character & graphical LCD/OLED drivers and touch‑controller interfaces
• Prototype features rapidly on Arduino‑compatible boards, leveraging BLE, Wi‑Fi, GSM/LTE, and LoRa modules for connectivity
• Port and configure Zephyr RTOS: board bring‑up, device trees, workqueues, ISRs, and watchdog timers
• Use STM32CubeMX/STM32CubeIDE and Renesas e2 studio to generate HAL/LL code, configure peripherals, clocks, and power domains
• Write Python scripts for automated test rigs, data logging, and regression suites
• Collaborate with hardware, mechanical, and QA teams to validate firmware on evaluation boards and prototypes
• Produce clear technical documentation, user guides, and release notes
• Participate in peer code reviews, maintain version control (Git), and integrate firmware into CI/CD pipelines

Qualifications

• 3+ years’ professional experience in Embedded C/C++ development on nRF52, STM32, or Renesas MCUs
• Solid Python skills for scripting and test automation
• Proven track record integrating sensors and driving LCD/OLED displays
• Hands‑on experience with Zephyr RTOS or comparable real‑time operating systems (FreeRTOS, Mbed OS)
• Proficient with STM32CubeMX/STM32CubeIDE and Renesas e2 studio for peripheral setup and HAL customization
• Familiarity with wireless stacks: BLE, Wi‑Fi, GSM/LTE, LoRaWAN, and AT‑command interfacing
• Comfortable building proofs‑of‑concept on Arduino frameworks
• Strong understanding of embedded build systems (Make, CMake), debuggers (J‑Link, OpenOCD), and logic analyzers
• Bachelor’s degree in Electrical/Computer Engineering or related field

Nice‑to‑Have

• Experience with secure‑boot, firmware signing, and OTA update architectures
• Background in low‑power design and battery‑management ICs
• Exposure to regulatory or quality‑system standards (ISO 9001, IEC 62304)
• Familiarity with CI/CD tools (GitHub Actions, GitLab CI) and automated hardware‑in‑the‑loop testing
