Embedded Engineer (part-time)

About the Project: It is an innovative MedTech solution designed for real-time cardiac monitoring. This system consists of a wearable chest device that records ECG data and transmits it via Bluetooth to a mobile application every 90 seconds. The data is then processed on the server and analyzed by healthcare professionals to provide life-saving prescriptions and insights. We are looking for a Senior Embedded Engineer to join our Delivery team on a part-time basis. You will be the technical heart of the hardware-software integration, ensuring the device is reliable, power-efficient, and secure. What you will do: - Develop and maintain embedded firmware (C/C++) for microcontroller-based devices; - Work with hardware components and integrate peripherals via UART/SPI/I2C/CAN; - Support hardware bring-up, testing prototypes and troubleshooting PCB-related issues; - Debug, optimize and improve firmware performance and stability; - Implement solutions using RTOS (tasks, interrupts, synchronization); - Collaborate with hardware, QA, and product teams, and maintain technical documentation. What we are looking for: - 5+ years of commercial experience in Embedded software development; - Strong knowledge of C/C++ and software design principles; - Experience with microcontrollers, specifically Nordic (nRF) and Silabs, including Nordic Connect SDK, LTE, and WiFi stacks; - Solid understanding of RTOS concepts (FreeRTOS, Zephyr, etc.); - Hands-on experience with embedded interfaces: UART, SPI, I2C, CAN, PWM, ADC; - Proven experience with AWS IoT Core and cloud integration; - Deep knowledge of wireless protocols: BLE, Wi-Fi, LoRa, Zigbee; - Proficiency with debugging tools: JTAG/SWD, oscilloscope, logic analyzer; - Solid understanding of low-level topics: interrupts, memory management, and bootloaders; - Experience with Git (knowledge of CI/CD pipelines is a plus); - Strong Hardware / PCB skills: ability to work closely with the hardware team, read/analyze schematics and PCB layouts; - Basic understanding of electronics: power supply, signal integrity, filtering, and noise issues; - Experience with hardware bring-up, board testing, and troubleshooting; - Working proficiency in English (Intermediate/B1 or higher), ability to read and interpret technical documentation in English (datasheets, reference manuals). Bonus points for: - Embedded Linux experience (Yocto / Buildroot); - Experience with safety/security standards (MISRA, ISO 26262, Secure Boot); - Knowledge of CI/CD pipelines. 📌 If you believe this role could be a great match for you, please send your CV — we will review it and get in touch with you if there’s a match.
