Data Engineer

Our mission is to make the retail economy of Pakistan radically more efficient.

Stores in Pakistan have been buying products in the same way for nearly a century. Why should 20 trucks deliver to the same store in a single day? Why do salespeople waste fuel to collect orders on scraps of paper? Why do store owners wait restlessly for someone to visit once a week to collect an order?

Tajir is a radical break from the past. We offer an app where stores can buy everything they need, delivered reliably the next day. We drastically reduce the number of vehicles on the road with efficient, centralized delivery, so both store owners and manufacturers enjoy higher profits. With $150B of purchases made by retailers annually, even modest efficiency gains have an outsized economic impact.

We are backed by Kleiner Perkins (early investors in Google, Amazon) and Y Combinator (early investors in Coinbase, Airbnb, Dropbox). Learn more about us on Forbes and Geo News.

1) Manage data pipelines. With so many users, it is easy to let our core data sink into a bowl of spaghetti. Our data engineers ensure the entire company works with clean, readable, consistent data.

2) Build tailored data products. Tajir’s operations emit tons of data. Our data engineers help us weaponize this data through dashboards and reports that drive operational efficiency and an improved customer experience.

3) Enable data-driven decisions. If it takes a week to answer a data question, people will make poor decisions using instinct and superstitions. Your job is to ensure this does not happen by enable rapid answers to all data queries.

We do not screen candidates by their experience with a specific tech stack. If you are a great engineer, you can adopt any new tools easily!

That said, because everyone asks – our Android app is built with Java and Kotlin using an MVVM Clean architecture. Our back end is built with Python and Flask and deployed to Google Cloud as Docker images. We use PostgreSQL for transactional data, and BigQuery for most analytics.
