What We Expect

We are seeking a highly skilled and self-motivated Embedded Systems Engineer (d/f/m) with deep expertise in modern C++ (C++17/20), Linux internals, and application-level networking.

In this role, you’ll contribute to the development of robust Linux user-space services and daemons, interface with devices through protocols like SPI, I2C, and GPIO, and help shape scalable and testable code using interface-driven design and unit testing practices.

Your ability to navigate system-level programming with tools like systemd, journald, and various Linux diagnostics will be key to ensuring performance and reliability.

Experience with REST, MQTT, and secure communication using TLS/mTLS will support cloud integration across our embedded systems.

Familiarity with Yocto, CI pipelines, and Agile workflows is a strong plus, as you'll be working closely with a cross-functional team to bring innovative and resilient solutions to life within TKE’s global product landscape.

At TKE, we are leading the digital transformation of the mobility industry worldwide, and we’re looking for passionate, forward-thinking professionals to join us in building the next generation of connected, intelligent elevators.
