Embedded Software Engineer – Wireless Access & IoT

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 working experience 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.

What You Gain by Joining Us

Work That Matters

Your firmware helps secure thousands of buildings worldwide and makes daily life safer and more accessible.

Autonomy in Action

Your expertise is trusted. You’ll influence architecture, explore new ideas and shape how our wireless locks evolve.

Growth with Purpose

Whether you want to deepen your embedded skills, explore wireless protocols or grow into technical leadership, we support your development.
