Data Scientist I

Quick Facts

• Role: Data Scientist I (Trust & Safety)

• Focus: Detect and reduce fraudulent or abusive activity on the platform

Description

Help detect and reduce harmful behavior by building scalable data-driven models and dashboards for fraud and abuse risk. You will work end-to-end—from framing the problem and preparing data to feature engineering, model evaluation on business metrics, and communicating results so stakeholders can take action.

Responsibilities

• Gather, prioritize, and prepare data from multiple sources, ensuring quality and clear definitions/limitations

• Perform exploratory analysis to identify patterns, segments, and signals for risk and policy decisions

• Engineer and select features to improve model quality and stability over time

• Apply statistical methods to describe distributions, relationships, and uncertainty

• Implement machine learning approaches suited to the problem (classification, ranking, clustering)

• Evaluate models using business-aligned metrics (e.g., precision/recall tradeoffs, calibration, segment performance) and iterate

• Interpret results, surface key drivers and caveats, and present them for both technical and non-technical teams

• Create charts and narratives for reviews, documentation, and operational readouts

• Partner with product, engineering, and operations to turn questions into scoped analyses and shipped solutions

Requirements

• Bachelor’s degree in Data Science, Statistics, Computer Science, or a closely related field

• 1+ years of experience in data science or equivalent analytics with examples of end-to-end work

• Strong programming in Python, including data manipulation and ML libraries

• Solid SQL and experience working with relational or warehouse-style data

• Grounding in statistics and machine learning, especially for rare event detection and highly imbalanced datasets

• Strong written and verbal communication, able to simplify technical work while retaining important tradeoffs

Benefits

• Eligible for 401k and a new hire and annual equity grant; C08+ may be eligible for annual bonus

• Comprehensive insurance and benefits (medical/Rx, vision, dental, life, disability, hospital indemnity, critical illness, accident)

• Parental leave and family services benefits; backup dependent care; flexible spending accounts

• Telemedicine, pet adoption reimbursement, employee assistance program, and discounts

• Unlimited PTO for exempt salary team members (subject to manager approval) and six paid holidays per year

• May be eligible for paid sick and family leave per applicable regulations
