We are looking for a big data expert with experience in hadoop, spark, presto, hive, mysql. You should be super experienced in setting up the hadoop architecture on any cloud server. On the high level, this is what the application needs to be doing. 1) We need to fetch a lot of data from several different apis which have different formats of responses and different data representations. 2) We need to clean this data and put them into a sql database. 3) This data will then need to be retrieved by an application that requires a data source which will be the datatable to reference - this is the front end that will pull the data from our database: http://www.tableau.com/ 4) Fetching data from these data endpoints / apis needs to be done in the most efficient manner possible and also retrieving data from our database needs to be efficient. We are looking for someone highly experienced in: - Big data and has experience in working with large / huge data sets of millions...

I'm looking for an experienced data scientist who has had some experience working on process optimisation (engineering related) problems. My data set is from a power plant desulphurisation process which has approx. 100,000 observations and 30 variables. Using this data set, I would like to model the number pumps used in the process with respect to the other variables. Then based on the derived model, you would need to find the optimal solution at which the number of pumps used is minimised subject to a few inequality constraints. This is an interesting problem and I'm confident that whoever takes on this challenge will find it rewarding! I would need the code written in R. Also, practical experience in Machine Learning and Nonlinear Programming would be required. If selected for an interview, further details about the project/expectation will be provided. I look forward to receiving your application.
