Information about the position

Job description, responsibilities and duties

We are looking for additional manpower for an ongoing project with a possibility of collaboration on future projects of our Electronics & Software department. Our department specializes in solving big problems with technologies that come in efficient and highly portable packages.

Over the years, we have worked with microcontrollers, digital signal processors and application processors from various manufacturers and product families. Every problem requires a slightly different set of tools to solve.

However, the specific project that you will be working on utilizes the following technology stack:
• STMicroelectronics STM32F4, STM32U5, STM32H5 (Arm® Cortex®-M33 and Arm® Cortex®-M4)
• Nordic Semiconductor nRF52, nRF53, nRF54 (Arm® Cortex®-M33 and Arm® Cortex®-M4)
• Sub-GHz RF Transceivers (custom packet protocols and control logic)
• Digital Signal Processing (audio and video encoding, processing, analysis)
• Bluetooth Low Energy (communication with Android companion app)
• Qt Framework for Windows/Linux/Android companion apps

We need you to have advanced, or ideally expert-level knowledge in the field of embedded development with several completed projects under your belt. You do not need to have direct experience with the aforementioned product families, we understand that if you have experience working with any Arm® Cortex®-M33/M4 microcontroller, a lot of your skills and knowledge will translate over to the STM32 or Nordic ecosystem. The same goes if you have experience with BLE, DSP on any other modern platforms.

Sometimes you will work on a task by yourself and other times as part of a team.
This will mostly depend on the complexity of the task at hand. You will take an active part in developing "quick n' dirty" proof-of-concept prototype software for use in feasibility studies as well as gradually bringing your software and documentation to perfection through feedback provided by our quality assurance and field testing processes.

Your salary will depend on your level of experience.
Do not hesitate to contact us even if you are a fresh graduate,
or if you only have experience with some of the bullet points of the technology stack.

You will be able to do ~99% of the work remotely, however we also have on-site laboratories which you can use to perform measurements, re-configure wiring, etc.
We offer fully flexible working hours and can adjust to your specific needs.

If you are a Slovak/Czech native, feel free to reply to this job posting in Slovak/Czech language.
