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.
