At BlinkTroll, we’re building next-generation training systems and defense technology used by military and police forces across Europe. Our mission is simple but urgent: to support the defenders of the free world with powerful, practical, and life-saving technology.

We’re currently looking for an Embedded Systems Engineer to join our R&D team, someone with strong experience in firmware development for STM32 microcontrollers, real-time digital signal processing, and embedded system integration. This is a great opportunity for someone who wants to work on advanced, performance-critical systems in a small, ambitious, and purpose-driven startup.

What You’ll Do

• Develop and maintain embedded firmware in C for STM32 microcontrollers.

• Implement real-time DSP algorithms and perform advanced signal analysis.

• Work closely with electronics, software, and mechanical engineers to deliver fully integrated systems.

• Design and integrate communication protocols (UART, SPI, I²C, CAN).

• Support system bring-up, debugging, and optimization in both lab and field conditions.

• Contribute to documentation, testing procedures, and continuous improvement of embedded systems.

• Participate in PCB design reviews and collaborate on hardware–software integration.

• (Nice to have) Assist with low-power design, FPGA/DSP module integration, and C++.

Who You Are

• 2–4 years of professional experience in embedded software engineering (or equivalent skill level).

• Strong proficiency in Embedded C for MCU platforms.

• Experienced with STM32 microcontrollers.

• Solid understanding of real-time signal processing concepts.

• Hands-on experience with communication protocols (UART, SPI, I²C, CAN).

• Practical experience with PCB design or PCB design reviews.

• You thrive in fast-moving, high-responsibility environments where your work directly impacts outcomes.

• Based in or near Odense, or willing to work on-site most of the time.

• Curious, reliable, and motivated to contribute to a mission-driven team.

What We Offer

• A meaningful mission and real-world impact.

• A hands-on, collaborative office in the heart of Odense’s robotics and defense ecosystem.

• A voice in product and technical direction from day one.

• Flexible hours (we’re office-first, but life happens).

• Strong team culture.

• Room to grow with the company.

Note: This position requires eligibility for security clearance.
