Senior Data Scientist at Change Research

About Change Research
Change Research innovates to solve critically important problems at the intersection of data, social science, and politics. Since 2017, Change Research has been at the forefront of measuring public opinion. Candidates, causes, cities, and companies use our data to understand people’s needs, improve messaging, and accomplish their strategic goals.  As a Senior Data Scientist at Change Research, you will be uniquely positioned to have the tools you build play a vital role in these decisions.
Data science has been a core ingredient in developing Change Research’s innovative survey methodology. It guides how we reach survey respondents, how we design and weight our surveys, and how we keep improving our techniques. It is also a core part of Change Research’s future. Data science will continue to improve our methods for acquiring survey respondents as well as develop new products grounded in our wealth of up-to-date survey data and new machine learning techniques.
This is a permanent, full-time, remote position that may require occasional travel and that reports to the Head of Engineering and Data Science.

This is a permanent, full-time, remote position and may require occasional travel and reports to the Head of Engineering & Data Science.
Core Responsibilities:
Partner with the product manager and engineering team on coming up with ideas for and developing fundamentally new public opinion products using artificial intelligence, machine learning, and data analysis using our massive dataset of survey respondents

A successful candidate will have:
3+ years of data analysis and building machine learning models in a Python-heavy codebase.

Experience with a data infrastructure stack — we use Redis, Google Cloud Platform (DataFlow, BigQuery, Cloud Run), Apache Beam, and MySQL all with Docker, but we believe experience in other stacks will translate.
The curiosity to try new things, but the self-discipline to prize results over technique.
Excitement to think about gaps in our tooling as opportunities for our team to improve and expand its data infrastructure, build new products, and surface new insights.
