Founded in Munich in 2025, Loxo Labs GmbH develops modular infrastructure systems that enable scalable autonomous drone operations. Our solutions cover the secure transport, storage, power supply and autonomous deployment of unmanned aerial systems.
You build the firmware that decides when a drone launches — real-time, safety-relevant, and running unattended in the field for weeks.
RESPONSIBILITIES
Develop the embedded software architecture of the system across the control, power and thermal subsystems
Build RTOS-based real-time control, including timing analysis and fail-safe behaviour for launch and recovery sequences
Build the low-level integration layer: CAN, UART, SPI, I²C, sensor drivers, and motor and actuator control
Design the firmware side of the command and control interface, including secure command handling and telemetry
Work on the secure firmware lifecycle: secure boot, signed images, field update strategy and rollback
Build out embedded test infrastructure — unit test, hardware-in-the-loop, automated regression and CI for firmware
Run FMEA on software-controlled functions and take firmware work packages through to done
Help shape our coding, review and release conventions
YOUR PROFILE
Someone who works hands-on and would rather build the thing and test it than specify it and wait.
Someone who is comfortable without a fully defined brief. At our size, the problem often arrives before the process does, and independent work is essential.
Someone who is not scared of taking on responsibilities.
C and C++ on resource-constrained targets, with hands-on RTOS experience: FreeRTOS, Zephyr, ThreadX or equivalent.
Real-time, safety-relevant or mission-critical systems — defence, aerospace, automotive, robotics or industrial control.
You read schematics, work with an oscilloscope and logic analyser, and debug at register level.
CAN, UART, SPI and I²C, and STM32, ESP32 or comparable MCU families.
You build the test and CI infrastructure, not only the features.
German and English.
WHAT WE OFFER
You build sovereign European defence technology
End-to-end ownership of a subsystem, from architecture through qualification to customer delivery
A ten-person company, which means your decisions reach hardware in weeks rather than quarters
An interdisciplinary team drawn from automotive and motorsport, aerospace, defence and industrial manufacturing
Direct influence on our engineering standards and processes as we scale
SECURITY AND EQUAL OPPORTUNITY
Because we work with customers in defence and critical infrastructure, a security clearance under the German Security Clearance Act (SÜG) may be required for this position.
We value diversity and welcome all applications — regardless of gender, nationality, ethnic and social origin, religion or belief, disability, age, and sexual orientation and identity.
