Job Description
Ajax Systems is an international technological company, the largest in Europe developer and manufacturer of Ajax security systems with the capabilities of smart home. It is a whole ecosystem of 135 devices, mobile and desktop applications, server infrastructure. Every year we demonstrate multiple growth in the number of the team and the number of users around the world. Currently, the company has over 3,300 employees. And Ajax sensors protect 2.5 million users in more than 187 countries around the world.
The System Department makes devices smart, turning them into a full-fledged IoT. They created and developed OS Malevich (modular RTOS for different hardware platforms) and the cloud service Ajax Cloud (Java 20 / Kotlin, AWS, Akka, NATS, Kafka, Mongo, MySQL). For controlling, servicing, and monitoring systems by users, installers, and security companies’ engineers, applications for iOS (Objective-C, Swift), Android (Java, Kotlin), Windows/macOS (Python / C++, QT, QML) were developed.
Lately, security has become increasingly important for both homeowners and businesses. Regardless of whether it is home protection, asset protection, or ensuring the safety of loved ones, the presence of a reliable security infrastructure has top priority. It is here that video surveillance systems offer a comprehensive solution for monitoring, recording, and analyzing activity on your territory and around it. Video surveillance systems have undergone a long way since their creation. From early video surveillance systems (CCTV) to modern IP cameras - the evolution of video surveillance technologies has been stunning. Instead of grainy video with low resolution, modern security cameras offer high-definition video, remote access, and intelligent analytical capabilities.
