Responsibilities/Scope of Work
Although the title suggests administration/maintenance work, the real essence of the work is R&D.
While no past programming experience is required, our aim is to develop custom systems based on extensive integration of existing F/OSS tools and packages, in particular those F/OSS tools built around Unix-system and Internet services such as those commonly used by large ISPs.

By fine-tuning multiple existing F/OSS projects and their integration into a well defined, well documented and heavily tested system, we expect to significantly shorten the development time, while developing extremely powerful solutions – in essence a best-of-bread Wireless ISP in-a-box.

In addition to the R&D work, this position calls for an active, on-going administration of existing and future servers/networks, in India and abroad, including the supervision, guidance and expansion of our in-house IT team of sysadmins.
