Senior Java Developer

Project description

The client has an installed base of hundreds of scanner systems worldwide. In order to meet up-time contract agreements, the system downtime must be kept to an absolute minimum. The traditional way to diagnose a system failure is to send engineers to a failing machine and let them execute the diagnostics and calibration procedures using a set of procedures and software tools. The client is about to change that way of working by introducing a server on-site that continuously monitors all scanners in a customer domain. The server must detect (upcoming) system failure and identify what corrective actions are needed via a knowledge and procedure database. In the calibration phase, this server will initiate the required service actions on the scanner with correct settings and timings (which is highly configuration dependent) The software running on the server is Java based. Core aspects of the design will be database management and information distribution (worldwide), performance efficient data collection schemes and data to information transitions.
