Senior Embedded Software Engineer (m/w/d)

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.

While much of the industry focuses on advancing drone technology itself, we address the infrastructure behind it — helping define an emerging category, Unmanned Infrastructure Systems (UIS).

You own the firmware that decides when a drone launches — real-time, safety-relevant, and running unattended in the field for weeks.

Responsibilities

• Owning the embedded software architecture of the system across the control, power and thermal subsystems
• Leading RTOS-based real-time control development, including timing analysis and fail-safe behaviour for launch and recovery sequences
• Owning the low-level integration layer: CAN, UART, SPI, I²C, sensor drivers, and motor and actuator control
• Designing and owning the firmware side of the command and control (C2) interface, including secure command handling and telemetry
• Establishing the secure firmware lifecycle: secure boot, signed images, field update strategy and rollback
• Building out embedded test infrastructure — unit test, hardware-in-the-loop, automated regression and continuous integration for firmware
• Running FMEA on software-controlled functions and driving firmware work packages
• Setting coding, review and release standards

Your profile

• 10+ years in embedded software for real-time, safety-relevant or mission-critical systems — defence, aerospace, automotive, robotics or industrial control
• Expert C and C++ on resource-constrained targets, with deep RTOS experience (FreeRTOS, Zephyr, ThreadX or equivalent)
• Strong hardware affinity: you read schematics, use a scope and logic analyser, and debug at register level
• Production experience across CAN, UART, SPI and I²C, and with STM32, ESP32 or comparable MCU families
• Track record building test and CI infrastructure for embedded work, not only features
• German and English

What we offer

• 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

The details

• Employment type: permanent, full-time
• Working language: German and English
• Requisition ID: 14404396

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.
