About us

Constructor.io powers product search and discovery for some of the largest retailers in the world. We serve billions of requests every week, 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’re approximately doubling year over year despite the market slow down and have customers in every eCommerce vertical. We’re a passionate team of technologists who love solving problems and want to make our customers’ and coworkers’ lives better. We value empathy, openness, curiosity, continuous improvement, and are excited by metrics that matter. We believe that empowering everyone in a company to do what they think is best can lead to great things.

Data Platform Team

The Data Platform team within Data Science and Engineering is an integral unit that serves internal stakeholders. It develops a data platform that

• Stores, processes data, produces artefacts the is used by the backend team to run in production
• Convenient tools for engineers to create, schedule, and run their data workloads.
• Data quality validation.
• Real-time Analytical API that serves analytics to our customers.

Data Science and Engineering consist of a mix of data engineers & analysts owning & collaborating on multiple projects. As a Data Platform team member, you will use world-class analytical, engineering, and data processing techniques to build the foundational infrastructure, tooling, and analytical capabilities and enable the business to move forward.

Challenges you will tackle

Constructor integrates with our customers by providing them with client-side libraries that interact with our API. These libraries transmit logs/events (behavioral events) that Constructor uses to

• Train ML models
• Make business decisions
• Conduct AB tests
• …and so much more

Logs are handled by Behavioral API — a Python service that collects them and stores in S3. This piece of infrastructure is owned by another team, and we’re about to take ownership to control the full data cycle from start to finish.

So your first task is:

• Separate the API and deploy it as a standalone service
• Integrate it with the Data Platform Team infra

We also have other long-term goals for the team, such as
