As of 2024 we have brought billions of dollars in credit to 12 million customers, doubling in the last two years while remaining strongly profitable and sustainable for the long term.

In this role, you will own the process of creating and maintaining scalable tools and infrastructure that handle hundreds of millions of transactions per month, ensuring high performance and reliability with a focus on data as a principle.

  • Drive the enablement of our modeling team by building new tools or adopting new technologies that will allow them to extract data, generate features, and deploy/serve models with ease.
  • Work with a data-driven mindset and understand the critical importance of handling data properly and safely.
  • Organize frameworks and develop processes in our codebase so that the easy and default coding style is cleanly structured.
  • Mentor other engineers and data scientists about best practices in engineering.

Requirements

  • Bachelor’s degree in Computer Science, Engineering, or a related field.
  • 3+ years of experience as a machine learning engineer, data engineer, or a closely related position with a proven track record of writing production-level code and developing and maintaining ML infrastructure.
  • Good verbal and written communication skills in English.
  • Comprehensive knowledge of ML life cycle: from data extraction and feature engineering to model serving and monitoring for live and batch processing.
  • High proficiency in Python and a strong understanding of its related libraries and frameworks (e.g., Scikit-Learn, Pandas, Flask, FastAPI, etc.).
  • Strong background in feature store implementation and usage (Chalk.ai, Tecton, Databricks, Feast, etc.), particularly focused on managing large volumes of data for online and offline processing.
  • Demonstrated experience with cloud providers (AWS preferred) and related data services (e.g., databases, storage, serverless computing).
  • Ability to work in a fast-paced environment with constant requirement changes.

Benefits

  • Company-funded Health and Dental Insurance for employees and immediate family members.
  • Life insurance.
