Job details

We’re seeking a Firmware Engineer to develop embedded systems that power our intelligent lighting and guest room control platforms. You’ll work on systems that manage lighting, HVAC, motorized shades, occupancy sensing, and user interfaces—ensuring seamless performance, luxury-grade reliability, and integration with hotel systems. Key Responsibilities Develop embedded firmware (C/C++) for lighting and guest room control systems, including dimmers, sensors, relays, touch panels, and smart thermostats Design and test Firmware for controlling Guest Room Control, lighting, HVAC, shading, and other in-room products Integrate communication protocols like DALI, DMX, RS-485, Modbus, and 0-10V for room and building system interfaces Conduct board bring-up, hardware validation, and firmware debugging using industry-standard lab tools Familiar with Silicon Labs microcontrollers and Zigbee stacks (e.g., EmberZNet PRO) and Atmel touch-enabled microcontrollers. Developing and implementing touch-based user interfaces for embedded devices. Understanding microcontrollers, RTOS (real-time operating systems), and resource-constrained environments. Embedded Linux knowledge would be an asset Optimizing firmware for efficiency and real-time processing. Working with cloud platforms and protocols (e.g., Google Assistant, Amazon Alexa). Identifying and resolving firmware issues. Capable to troubleshoot firmware/hardware Author detailed design documentation, installation manuals, and test procedures Implement comprehensive testing procedures to ensure firmware meets performance requirements and security standards Ensure products meet safety, EMI, and reliability standards (e.g., UL, FCC, CE) Required Qualifications Bachelor’s in Electrical Engineering, Electronic Technologies, Computer Science 3+ years of experience in embedded firmware/Hardware Experience with microcontrollers (e.g., STM32, NXP, Silicon Labs) and embedded C/C++ Familiarity with guest room control systems and lighting control protocols (DALI, DMX, 0-10V, etc.) would be an asset Experience working with low-voltage systems (24VDC, 120/277VAC interfaces) Skilled in debugging hardware and firmware with tools like oscilloscopes and logic analyzers #LI-VS1 We are the ASSA ABLOY GroupOur people have made us the global leader in access solutions. In return, we open doors for them wherever they go. With nearly 63,000 colleagues in more than 70 different countries, we help billions of people experience a more open world. Our innovations make all sorts of spaces – physical and virtual – safer, more secure, and easier to access. As an employer, we value results – not titles, or backgrounds. We empower our people to build their career around their aspirations and our ambitions – supporting them with regular feedback, training, and development opportunities. Our colleagues think broadly about where they can make the most impact, and we encourage them to grow their role locally, regionally, or even internationally. As we welcome new people on board, it’s important to us to have diverse, inclusive teams, and we value different perspectives and experiences.
