Embedded Security Engineer (80-100%)

Summary

Belimo is building the next generation of intelligent HVAC devices — and that requires firmware that is fast, reliable, and secure at the lowest level. In this role, you’ll be a key technical expert for embedded security stack for our platform.

What You'll Do

• Lead the porting, adaptation, and integration of Trusted Firmware-M (TF-M) for our platform
• Contribute to the security architecture of our embedded platforms (secure services, isolation concepts, lifecycle considerations)
• Design, develop, and maintain high-performance low-level firmware in C/C++
• Write robust, memory-efficient, real-time capable code for resource-constrained environments (bare-metal and/or RTOS)
• Debug complex issues at the hardware–software boundary using JTAG/SWD, logic analyzers, and instrumentation
• Drive performance optimization and quality of foundational firmware components used across product lines
• Help shape the long-term cybersecurity roadmap 

Who You Are

• Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, or a related field

• Strong track record in low-level embedded development for constrained systems (bare-metal and/or RTOS)

• Expert proficiency in C for embedded systems; solid C++ experience in embedded contexts

• Deep understanding of microcontroller/SoC architecture (ARM Cortex-M preferred)

• Familiarity with embedded security concepts (e.g., TrustZone, secure boot, TEE patterns); TF-M experience is a strong plus
