Beschreibung
The Atacama Large Millimeter/submillimeter Array (ALMA), an international partnership of Europe, North America and East Asia in cooperation with the Republic of Chile, is the largest astronomical project in existence. ALMA is a single telescope of revolutionary design, composed of 66 high precision antennas located on the Chajnantor plateau, at 5000 meters altitude in northern Chile. All antennas are now at the ALMA site and the Observatory is transitioning towards full-scale science operations.
Our customer is looking for a software engineer to assist in the set-up of a Cassandra cluster to store and allow querying of time-series data from the hardware of the ALMA radio telescope in Chile. Our customer is storing readings from 200,000 sensors, at a rate of up to one per second.
A test cluster consisting of 6 Servers is already in place and our customer need assistance to improve this cluster, optimise the configuration, understand any issues, and help to draft operational procedures in conjunction with the operations team in Chile. They also need assistance in finding the optimal schema to store the data in a performant, flexible way. A secondary role would be to modify client code for accessing the data.
necessary knowledge:
University degree in Computer Science, Physics, Electrical Engineering or equivalent.
Experience of Cassandra is a must - from configuration to schema design.
A logical and thorough way of approaching problems is essential as is the ability to communicate clearly in English.
nice-to-have:
An understanding of lower-level issues such as linux and storage configuration is a plus.
Nice-to-have skills include Java development and knowledge of Apache Spark
remote working is also a possibility with at least a 1 week visit in Garching at the contract start!
