We are makers and builders. We challenge the status quo and have fun doing it. We bring passion and purpose to making a difference in healthcare, elevating how care is delivered and experienced. Inside health systems, where every second can matter, operations are still spread across dozens of disconnected tools and platforms. Kontakt.io is changing that.
We combine proprietary hardware, AI-powered intelligence, and deep integrations with the technology health systems already have in place to build real-time understanding of what's happening across their operations. That intelligence becomes the execution layer care teams have been missing, helping them make smarter decisions and deliver better patient care.
Backed by Goldman Sachs and trusted by leading health systems including HCA Healthcare, Sutter Health, AdventHealth, Trinity Health, Northwell Health, Cleveland Clinic, and the U.S. Department of Veterans Affairs, we’ve more than doubled our revenue and are rapidly scaling with a clear path toward $100M in annual recurring revenue.
If you're excited to solve hard problems and help health systems deliver better care, we'd love to meet you!
Senior Hardware & Firmware Engineer
About the Role
Our devices sit at the physical edge of the Kontakt.io platform — battery-powered BLE tags, badges and gateways that deliver real-time location intelligence for patients, staff and assets in hospitals worldwide. Thousands of them run in the field, in regulated healthcare environments, and they have to keep working without anyone touching them.
We're hiring a Senior Hardware & Firmware Engineer to join our Firmware team in Kraków. Most of your time will go into firmware — but we're specifically looking for someone with an electrical / electronics engineering background: someone who has designed and tested boards, brought them up, measured them and found out why they didn't work. You'll be the person who can look at a schematic or a misbehaving board and tell us what's really going on.
You won't be designing boards from scratch every day. You'll review and correct designs, test and validate boards in our own lab, and build proof-of-concept hardware when we need to try something quickly.
If you spent a few years as an electronics / hardware engineer and then moved closer to firmware because you wanted to own the whole device — this role was written with you in mind.
What You’ll Do Firmware — most of your time
Design, write and maintain production firmware in C for Nordic Semiconductor (nRF) microcontrollers on our battery-powered devices
Build and extend BLE features used for indoor positioning and device-to-cloud communication
Write and debug low-level drivers for sensors and peripherals (SPI, I2C, UART, ADC)
Develop bootloader and firmware update (OTA) functionality, and keep devices updatable safely in the field
