Podsumowanie oferty

Senior Hardware & Firmware Engineer working on battery-powered BLE tags, badges and gateways that provide real-time location intelligence for hospitals. The role focuses on production firmware for Nordic nRF microcontrollers, alongside reviewing, testing and prototyping hardware boards.

Wymagania

5+ years of engineering experience on commercial hardware products.
Background in electrical or electronics engineering, including hands-on board design, testing and validation.
Commercial firmware experience in C on microcontrollers (ARM Cortex-M or similar), including drivers, RTOS or bare-metal development, and debugging on target.
Ability to independently read and review schematics and PCB layouts, and explain proposed changes.
Experience bringing up and debugging boards using lab equipment such as an oscilloscope, logic analyser, multimeter and soldering equipment.
Understanding of low-power design and how hardware and firmware together affect battery life.
Working knowledge of serial interfaces and peripherals (SPI, I2C, UART, ADC, GPIO) on both sides of the wire.
Solid Python skills for scripting, test automation and tooling.
Practical use of AI coding tools in day-to-day work.
Fluent spoken and written English.

Nice to have:

Experience with Nordic nRF.
Experience with Zephyr RTOS.
RF / wireless fundamentals, including BLE, antenna matching and RF testing.
Experience with PCB design tools such as Altium or KiCad.
Experience taking a device through production, including DFM, test fixtures and production testing.
Exposure to certification and EMC pre-compliance (CE / FCC).
Background in IoT, healthcare or other regulated device environments.
