Machine Learning Engineer: Search Team
Constructor, United States

You’re a machine learning engineer who loves coming up with creative solutions to multifaceted problems like search relevance. You evaluate your solutions using online metrics such as purchase rates, revenue per visit, and other metrics truly important to a retail business. You see vanity metrics from a mile away and immediately call them out. You strive to develop fully automated pipelines and models that work seamlessly and as widely as possible, given different data contexts such as language or signal density. You take pride in your reliable code and embrace automated testing as unequivocally good. You are motivated to balance cutting edge technology with stability and robustness to build something truly useful. You want to build things you can be proud of, and work with an international team of experienced, passionate engineers.

As a Machine Learning Engineer in the Search team, you'll be designing and delivering the models that are at the core of our ranking algorithms. From research and experimentation to productionizing and a/b testing, you will be working on all stages of result quality projects. You’ll help determine which metrics we need to optimize to keep customers happy, and which technologies we use to help users find what they need as efficiently as possible.

Constructor.io powers product search and discovery for some of the largest retailers in the world, like Sephora and Backcountry. We serve billions of requests every year, and you’ve probably seen our results somewhere and used our product without knowing it. We differentiate ourselves by focusing on metrics over features, and reinventing search and discovery from the ground up as a machine learning challenge with the specific goal of improving metrics like revenue. We have grown several hundred percent YoY for the last 2 years and have customers in every eCommerce vertical, around the world, and spanning many languages.

We’re a passionate team of technologists who love solving problems and want to make our customers’ and coworkers’ lives better.
