About The Role

We have a diverse, multi-disciplinary team. The Big Data Engineer role exists to provide engineering subject matter expertise in our client projects. This may be at the designing/planning stage or at the building/testing stage, or both. Within a project there may be one or more Big Data Engineers, depending on the size and complexity of the work.

While the work you will do each day can vary, the following are some common tasks that you are likely to get involved in.

Designing, implementing and testing end-to-end data processing pipelines. This usually means selecting and integrating the appropriate Big Data tools and frameworks for the job in hand, and can involve any or all of the following:Databases and storage methods; Messaging systems, such as Kafka; Big Data ingestion tools or frameworks; Data processing engines/frameworks; Orchestration and resource management; Integrating into downstream Machine Learning pipelines; Data wrangling and Visualisation. In addition to implementing the pipelines, best practice QA, environment setup and ongoing governance are first order concerns: Documenting test cases and doing code reviews; Provisioning appropriate resources, and configuring them thoughtfully; [Depending on experience] Planning, designing and implementing hybrid cloud architectures that incorporate on-premise and public/private cloud components. Planning and implementing appropriate (roles based) access control; Setting up effective monitoring, and refining configuration on an ongoing basis to maximise the signal:noise ratio; Building useful metadata collection into the pipeline; Maximising automation and configurability, using Airflow or other tools/techniques.
