ABOUT THE PROJECT

Within this project, you’ll be a member of one of the globally distributed teams and contribute to the development of an IoT platform that aims to deliver a cutting-edge AWS-based smart home technology solution tailored specifically for multifamily residential communities. The system is designed around a patented LoRaWAN thermostat, which includes embedded smart hub technology and integrates seamlessly with top-tier smart door locks and devices. On the Klika Tech side, we are responsible for the system’s end-to-end behavior, including front-end, back-end, and mobile applications.

We hire in Kraków, Wroclaw, and Warsaw only. You can choose the type of work: hybrid/remote/office.

PROJECT’S GLOBAL IMPACT

Our Smart Home technology solutions have positively impacted the following areas:

• Environmental Sustainability: By incorporating energy-efficient technologies and optimizing energy and water usage, we contribute to reducing carbon footprint and promoting environmental sustainability.
• Safety and Accessibility: Features like smart locks, security cameras, and smoke detectors connected to centralized monitoring systems enhance the safety and security of residents, helping to prevent accidents and unauthorized access. Many smart locks allow doors to be unlocked without the use of physical keys, which makes it more convenient to access apartments and avoid losing keys.
• Quality of Life and Inclusivity: Smart apartment solutions can be designed with accessibility in mind, ensuring that features are user-friendly and accommodating for residents with diverse needs, particularly for individuals with disabilities or mobility issues.
• Smart Cities Initiatives: By developing solutions that align with smart city initiatives, we contribute to global urban sustainability goals. Smart apartment technologies can integrate with city-wide systems for energy and resource management, waste reduction, and transportation, supporting broader efforts to create more sustainable and livable urban environments.
