The posting
zerothird is a Vienna-based deep-tech company specialising in entanglement-based Quantum Key Distribution (eQKD). Our technology - rooted in Nobel Prize-winning research on quantum entanglement - enables encryption keys to be generated locally from entangled photon states, making interception physically impossible.
We develop and deploy the full hardware and service stack for quantum-secure communications, targeting critical infrastructure, financial institutions, and government organisations across Europe.
As part of our next-generation hardware platform development, we are looking for an experienced Embedded Systems & FPGA Engineer to join our core engineering team.
If you are excited about building cutting-edge quantum communication technology at the intersection of embedded Linux and FPGA development, we would love to hear from you. 1 Embedded Systems & FPGA Engineer (all genders) Key Responsibilities
Embedded Linux & Firmware
* Develop and maintain embedded Linux BSPs, including kernel configuration, device tree authoring, and board bring-up.
* Write Linux device drivers and kernel modules for custom FPGA peripherals and on-board hardware.
* Implement low-level firmware and middleware in C/C++/Rust for FPGA logic and communication interfaces.
* Configure and optimize bootloaders and root filesystems for embedded CPU modules.
* Develop userspace applications and automated hardware testing tools.
FPGA Design & Integration
* Implement RTL designs in VHDL/Verilog/SystemVerilog.
* Integrate vendor and custom FPGA IP cores and define HW/SW interfaces.
* Support simulation, verification, synthesis, timing closure, and in-system debugging.
* Collaborate closely during board bring-up and system integration activities.
System Integration & Debugging
* Debug complex HW/SW/FPGA interactions using laboratory equipment and protocol analyzers.
* Contribute to system architecture, documentation, and interface specifications.
What You Bring
* Several years of experience in embedded systems engineering, FPGA development, or mixed HW/SW engineering.
* Strong experience with embedded Linux, kernel drivers, device trees, and bootloaders.
* Solid proficiency in C/C++ and/or Rust.
* Experience with RTL design and FPGA integration.
* Hands-on debugging experience in hardware environments.
* Ability to work independently in a fast-moving engineering team.
Nice to Have
* Experience with Rust for embedded systems.
* Familiarity with RTOS environments such as FreeRTOS or Zephyr.
* Experience with Xilinx/AMD SoC platforms and toolchains.
* Scripting experience using Python, TCL, or Bash.
* Knowledge of PCIe, DDR, Ethernet, or DSP toolchains.
What We Offer
* The opportunity to work on cutting-edge quantum-secure communication technology.
* Direct impact on a next-generation hardware platform from concept to production.
* High autonomy and ownership in a small, highly skilled engineering team.
* Collaboration within a strong European deep-tech ecosystem supported by EU programmes and leading investors.
* Long-term growth opportunities into specialist or technical leadership roles.
