Company Description

Since we opened our doors in 2009, the world of commerce has evolved immensely, and so has Square. After enabling anyone to take payments and never miss a sale, we saw sellers stymied by disparate, outmoded products and tools that wouldn’t work together.

To solve this problem, we expanded into software and built integrated solutions to help sellers sell online, manage inventory, book appointments, engage loyal buyers, and hire and pay staff. Across it all, we’ve embedded financial services tools at the point of sale, so merchants can access a business loan and manage their cash flow in one place. Afterpay furthers our goal to provide omnichannel tools that unlock meaningful value and growth, enabling sellers to capture the next generation shopper, increase order sizes, and compete at a larger scale.

Today, we are a partner to sellers of all sizes – large, enterprise-scale businesses with complex operations, sellers just starting, as well as merchants who began selling with Square and have grown larger over time. As our sellers grow, so do our solutions. There is a massive opportunity in front of us. We’re building a significant, meaningful, and lasting business, and we are helping sellers worldwide do the same.

  • Uplevel the overall org’s data pipeline, experimentation, and ML foundations.
  • Contribute to the next generation of data-driven and intelligent products at Square.


You have:

  • 4+ years of industry experience in ML or a Ph.D. in a related field with 2+ years of experience.
  • Fluency in Python and practical experience in applying CICD best practices.
  • Excellent breath and depth in ML fundamentals.
  • Experience with cloud based ML pipelines on GCP or AWS.
  • Experience launching end-to-end production ML models.
  • Experience in automating internal business processes via data and ML solutions.
  • Experience in stakeholder management and cross-functional collaboration.
  • The ability to clearly communicate complex concepts to technical and non-technical audiences.

Nice to have:

  • Experience with designing and evaluating A/B tests for newly launched models.
  • Experience building ML solutions for customer-facing teams.
