Java JEE Designer


High Tech

Achtergrond opdracht


The organisation has an installed base of hundreds of scanner systems worldwide. In order to meet uptime contract agreements the system down-time 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.
This way-of-working introduces travel time and relies on the skills of individual engineers.
The organisation is about to change that way of working by introducing a server on-site that continuously monitors all scanners in a customer domain.

Job Mission

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 dependant). The software running on that server will be JEE based. Core aspects of the design will be database management and information distribution (worldwide), performance efficient data collection schemes and data to information transitions. A team of architects has been working out the high level concepts and some parts of the software are being build and tested now. PC based Java versions are available and now to be migrated to client-server. The team needs to scale up with developers/engineers that have profound JEE knowledge and are eager to become part of this product development team.

Job Description

- Support the architects in the translation from high level design to work-break down.
- Writing and updating detailed Element Design Specification Documents
- Code development in JEE.
- Interface Design between JAVA EE modules and when needed the ASML factory SAP environment.
- Define test strategies and if needed execution of software tests, set-up (automated) testing.
