**Department/Project Description**
Connected devices are everywhere - in factories, fields, city streets and remote villages. But without reliable connectivity, it's just a device. That's why we built our IoT platform - an easy to use solution that provides global connectivity management enabling any enterprise to achieve infinite connectivity. Now any business can connect and handle devices easily, securely, and globally. Our IoT Accelerator handles global IoT connectivity with reliability, security, and cost-efficiency. As the only global platform with a dedicated core network, it provides outstanding scalability, quality of service and unified user experience for IoT deployments of any size, anywhere in the world.
We are responsible for the development and maintenance of M2M features found in IOTA like SIM ordering, M2M provisioning, subscription management as well as rating/billing for Operators or their Enterprises. IOTA supports 2G, 3G, 4G and 5G NSA messaging and packet switched services. IOTA development the features that build up the actual services exposed on our platform whilst the day to day running of that platform (Production) is handled by our colleagues in the NOC. Our IOTA solution consists of two areas, Device Connectivity System (DCS) and Business Support Systems (BSS). We want to strengthen the DCS team with more IP Networking (MPBN) experience. In DCS, we have both products, such as STP, EPG, vEPG, UDC (HLR-FE, CUDB, PG), LTE (HSS-FE, DSC), MPBN including IPWORKS, SAPC and 3PP, such as SMSC from Sinch and OSIX probes from Polystar.
