About Hopper

At Hopper, we’re on a mission to build the most customer-centric travel company on earth. We are leveraging the power that comes from combining massive amounts of data and machine learning to build the world’s fastest-growing mobile first travel marketplace -- one that enables our customers to save money and travel better.

Hopper’s goal is to reduce traveler anxiety throughout all stages of the trip buying and taking process. By creating a transparent travel marketplace and unique, data-driven financial technology products focused on providing peace-of-mind, Hopper adds value along each step of the customer’s journey.

Hopper has launched several bespoke fintech products that leverage our immense first and third-party data to create products and value that do not exist elsewhere - including Refundable and Flexible Tickets and Price Freeze. Thanks to these offerings, Hopper’s revenue growth is up 112% despite the travel slowdown due to COVID-19.

With over $250M CAD in funding from leading investors in both Canada and the US, Hopper is primed to continue its acceleration to becoming the world’s fastest-growing end-to-end customer-centric travel offering.

Recognized as one of the world’s most innovative companies by Fast Company three years in a row, Hopper has been downloaded over 50 million times and sees over 1 million new installs per month. The app has received high praise in the form of mobile accolades such as the Webby Award for Best Travel App of 2019.

THE ROLE

We’re looking for a data science intern to audit data integrity, document the data architecture and drive data quality improvements in collaboration with our backend infrastructure engineers. Because 80% of data science work involves data wrangling, this work improves the analytical correctness and velocity of all data scientists.

This includes systematically documenting a data science dictionary that solves problems like:

Knowing which table and field has the data you’re looking for

Knowing the technical definition and vernacular definition of the data field

Knowing the direct source or calculation behind the data field

Knowing which fields can be used to join which tables

Identifying variables that have different names in several different tables

Identifying variables that have the same name in different tables but give different values

Identifying variables that are foundational to the business but are currently missing

Finding violations of assumed 1:1, 1:many, many:1 relationships

Finding anomalies in distribution over time

Finding anomalies in crosstab distributions

Finding incorrect duplications of entire row records within the table or incorrect duplications of certain fields

This person would also work with Engineering to communicate mistakes found, recommend changes, create SQL views of “gold standard sources of truth” and track Engineering corrections over time.

They would create a Data Science version of an Entity Relationship Diagram (e.g. what are the “quantum” units of different “objects” like clients, app events, policies and requests and how they all relate to each other).

They would document idealized business metrics, what proxy metrics currently exist and what new metrics could be created to bridge the gap.

THE TEAM

Leveraging data science to solve customers’ problems is in Hopper’s DNA. While this began with helping customers plan and book travel more intelligently, we have extended our capabilities to ensure customers secure the best fares for their trips with unique product offerings like Price Freeze. These product offerings currently make a large fraction of Hopper’s revenue and have helped drive Hopper’s growth despite the travel slowdown due to COVID-19.

Customers that book with Hopper and use Price Freeze can be confident they won’t miss out on a great deal. Price Freeze lets customers that are not yet ready to book lock in great flight deals at a low cost for anywhere from 12 hours to 14 days.

An Ideal Candidate Has

A degree in Math, Statistics, Computer Science, Engineering or other quantitative disciplines

At least 1 year’s academic or practical experience in SQL

At least 1 year’s academic or practical experience in data wrangling with Python Pandas

The ability to write code in both SQL and Python for common data wrangling tasks

Excellent written communication skills with a non-technical writing sample required

Any of the following experiences would be nice to have but not required: git, BigQuery, Jupyter, handling JSONs, experience with extremely large datasets
