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 SoCs, 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:
• Allwinner „V“-series SoCs
• Linux application development
• Linux user space (rootfs) development (Buildroot)
• Implementation of hardware accelerated audio/video processing, analysis and encoding (H.264, H.265)
• System-level low power optimization (sleep modes, etc.)

Non-required but beneficial skills and experience to have:
• NXP i.MX 8M series SoCs
• Linux kernel and driver development
• Bare metal/RTOS firmware development
• Sub-GHz RF Transceivers (development of custom packet protocols and control logic)

We need you to have advanced, or ideally expert-level knowledge in the field of embedded Linux 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® based SoC, a lot of your skills and knowledge will translate over to the Allwinner or NXP ecosystem.

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.
