Job description

Daltix is enabling retailers & suppliers to make decisions based on data rather than gut-feeling and for that it’s built up significant experience in how to collect data but also how to transform it in order to support decision making. To this end we’re looking for a data engineer/analyst who’ll aid some of the biggest names in the industry (don’t take our word for it, check our website) in becoming truly data-driven.


We’re looking for a Data Engineers to join our data teams that are in charge of standardizing and extracting information from the data we collect as well as making it accessible for analytics & reporting.

We need people to aid us with:

  1. Adding new data processing modules to our pipeline so we can standardise data collected from the web.
  2. Managing the infrastructure (schedulers, computing frameworks) used for our big scale data processing & reporting.
  3. Quality Assurance of our data. We have some tooling in place already, but some more might be necessary. You will likely want to automate some of these checks.
  4. Assist with existing ETL pipelines that make our data ready to use by our customers.
  5. Enabling our professional services team by providing Python based toolkits to make their jobs easier.
