Data Platform Engineer

HL Tech is a modern technology centre supporting software development and strategic digital transformation of the British financial market giant, Hargreaves Lansdown (HL). HL is the UK’s number one platform for private investors, looking after £132.3 billion of savings and investments on behalf of over 1.7 million clients.

HL Tech was founded in July 2017 in Warsaw and currently employs 80 of the best IT experts in their field, who focus on clean code, autonomy in projects, customer needs, best practices, and good design. At HL Tech, we create a space for innovation and development based on the culture of knowledge sharing, constant learning, feedback, and friendly atmosphere.

As part of our data strategy we are investing into a new data platform with AWS. This platform will enable us to combine data from multiple sources and analyse it in batch or near real time, unlocking the value behind our data.

The role of the Data Platform Engineer is focused on the cloud platform itself, being responsible for the setup, deployment and running of the infrastructure. You will do this by creating infrastructure as code, following the best practice defined in our SDLC and architectural principles. This role is more focused on the devops side of the platform (instead of creating data pipelines) and ensures that the platform evolves to support the business use cases.
