Job description

Meet the Team

You will be member of Big Data Systems Group. We are part of the Core-Development Department

within Technology Division. Out main focus is storing, indexing, and processing various

forms of malware-related data, and meta-data we receive from many different sources.

While the Big-Data Ecosystem contains huge pool of mature systems and solutions for

all seasons, still many problems remain to be tackled by an in-house software

our in-house tools for specific big-data-related problems not addressed sufficiently

by the existing systems, or tools. The main programming languages we use at present

- at least user-level experience with Linux (as almost everything is developed for Linux servers)

Desirable (nice to have) Requirements

- any other programming skills/experiences are welcome

(feel free to mention even things like Lisp, Haskell, Prolog, Ruby, Erlang, or Forth :-)

- real-life experience with vibe coding is a bonus

- experience with any Big-Data related technologies (Openstack-Swift, Kafka, Spark...) - user, programmer, or administrator is highly valued

- practical database knowledge (user or programmer; SQL or noSQL; ACID or not) is appreciated

Basic wage component (brutto): from 2500€/month (brutto). For senior professionals, the starting salary is from 3000€/month.

* The final basic wage component can be increased accordingly to individual skills and experience of the selected candidate.

* Performance bonus 2 times per year up to 10% of the basic salary paid for the evaluation period(usually 6 months)
