Description
We are looking for a Big Data Engineer that will work on the collecting, storing, processing, and analyzing of huge sets of data. The primary focus will be on choosing optimal solutions to use for these purposes, then maintaining, implementing, and monitoring them. You will also be responsible for integrating them with the architecture used across our clients.In this task, you will lead a team of data engineers and data scientists to:
Assess existing big data ecosystem: architecture, data sourcing, systems integration required to monetise the data
Understand specific requirements to evolve existing big data ecosystem and perform gap analysis/roadmap definition
Implement specific big data use-cases by sourcing internal and external data, building data layers, developing analytics algorithms, models and visualisation and overseeing the implementation of 3rdparty tools to monetise data
Specifically:
Selecting and integrating any Big Data tools and frameworks required to provide requested capabilities
Gather and process raw data at scale (including writing scripts, web scraping, calling APIs, write SQL queries, etc.)
Process unstructured data into a form suitable for analysis and then execute analysis
Support business decisions with ad hoc analysis as needed
Work closely with client engineering team to integrate your innovations and algorithms into production systems
Professional background
