Who you are

We're looking for someone who meets the minimum requirements to be considered for the role. If you meet these requirements, you are encouraged to apply.

The preferred qualifications are a bonus, not a requirement.

Minimum requirements

• Over 3+ years industry experience building machine learning applications in large scale distributed systems.
• 2+ year of experience working within a team responsible for developing, managing, and optimizing ML models or ML infrastructure
• Experience designing and training machine learning models to solve critical business problems
• Experience performing analysis, including querying data, defining metrics, or slicing and dicing data to model performance and business metrics

Preferred qualifications

• An advanced degree in a quantitative field (e.g. stats, physics, computer science)
• Proven track record of building and deploying machine learning systems that have effectively solved critical business problems
• Experience in adversarial domains like Payments, Fraud, Trust, or Safety
• Experience working in Python, Java and / or Ruby codebases
• Experience in software engineering in a production environment.

Hybrid work at Stripe

This role is available either in an office or a remote location (typically, 35+ miles or 56+ km from a Stripe office).

Office-assigned Stripes spend at least 50% of the time in a given month in their local office or with users. This hits a balance between bringing people together for in-person collaboration and learning from each other, while supporting flexibility about how to do this in a way that makes sense for individuals and their teams.

A remote location, in most cases, is defined as being 35 miles (56 kilometers) or more from one of our offices. While you would be welcome to come into the office for team / business meetings, on-sites, meet-ups, and events, our expectation is you would regularly work from home rather than a Stripe office.

Stripe does not cover the cost of relocating to a remote location. We encourage you to apply for roles that match the location where you currently or plan to live.
