Build the Future of Wireless Access with Us
Location: Stockholm, Sweden
Hybrid │ Digital & Access Solutions EMEIA

Embedded systems shape how people move, work and feel secure — and so will you.
As an Embedded Software Engineer in our Wireless Lock product unit, you help bring APERIO®, our world-leading wireless access platform, to life. The firmware you build runs in real products used in hospitals, universities, workplaces and public buildings.

If you want a role where technical depth meets purpose — and where secure, low-power, connected devices are your playground — this is where your impact becomes visible.

Your Role

You’ll work hands-on with the firmware that powers our wireless locks and influence how they perform, connect and evolve.

Design, Build, Deliver

• Develop reliable, secure firmware for wireless, battery-powered locks
• Implement features on ARM Cortex MCUs (M0–M4) using C
• Debug at a low level using oscilloscopes, logic analysers and hardware tools

Engineer for a Connected World

• Work across RTOS and bare-metal environments
• Apply modern embedded practices, including CI/CD and automated testing
• Improve system performance, stability and long-term efficiency

Advance Wireless Access Technology

• Enhance connectivity features (BLE, Zigbee, NFC/ISO14443, UWB) and low-power performance
• Bring insights from IoT trends, cybersecurity and standards into development

What You Bring

• Strong skills in embedded C development on ARM Cortex MCUs
• Ability to debug deeply using hardware tools
• Experience with RTOS or bare-metal environments
• Familiarity with CI/CD and structured development practices
• Clear communication and a collaborative, solutions-focused mindset

Nice to have / keen to develop: BLE/Zigbee, low-power design, credential technologies or IoT security trends.
