Lead Data Scientist (UGC)

Scribd•San Francisco, CA

About The Position

At Scribd Inc. (pronounced “scribbed”), our mission is to spark human curiosity. Join our team as we create a world of stories and knowledge, democratize the exchange of ideas and information, and empower collective expertise through our four products: Everand, Scribd, Slideshare, and Fable. This posting reflects an approved, open position within the organization. We support a culture where our employees can be real and be bold; where we debate and commit as we embrace plot twists; and where every employee is empowered to take action as we prioritize the customer. When it comes to workplace structure, we believe in balancing individual flexibility and community connections. It’s through our flexible work benefit, Scribd Flex, that employees – in partnership with their manager – can choose the daily work-style that best suits their individual needs. A key tenet of Scribd Flex is our prioritization of intentional in-person moments to build collaboration, culture, and connection. For this reason, occasional in-person attendance is required for all Scribd Inc. employees, regardless of their location. So what are we looking for in new team members? Well, we hire for “GRIT”. The textbook definition of GRIT is demonstrating the intersection of passion and perseverance towards long term goals. At Scribd Inc., we are inspired by the potential that this can unlock, and ask each of our employees to pursue a GRIT-ty approach to their work. In a tactical sense, GRIT is also a handy acronym that outlines the standards we hold ourselves and each other to. Here’s what that means for you: we’re looking for someone who showcases the ability to set and achieve G oals, achieve R esults within their job responsibilities, contribute I nnovative ideas and solutions, and positively influence the broader T eam through collaboration and attitude. About the Role Scribd’s Data & Analytics team is hiring a Lead Data Scientist to own measurable outcomes across our UGC (User Generated Content) ecosystem for Scribd and Slideshare and help transform our products in the AI era. You’ll translate product goals into a durable metrics strategy, lead strategic bets, and ship meaningful improvements in business results. You’ll also define how we segment target audiences and prioritize investments across user generated content, then prove impact through measurement and experimentation. Scribd is a differentiated subscription platform with strong organic reach and a vast catalog—hundreds of millions of UGC documents and slides. You’ll build a trusted measurement foundation (north stars, guardrails, and leading indicators) so teams can make fast, reliable decisions that improve user experience and long-term value. You’ll lead high-impact UGC bets end-to-end, especially for AI-driven features, turning ambiguity into crisp hypotheses, experiments, and evaluation frameworks in close partnership with Product, UXR, Design, Engineering, and Content. You’ll surface the “so what” through executive-ready memos that clearly spell out impact, tradeoffs, risks, and what we’ll monitor, helping answer the strategic questions that shape how Scribd and Slideshare best serve their audiences.

Requirements

8+ years of experience in Data Science with demonstrated shipped impact (subscription business/consumer products/UGC a plus)
Strong Python and SQL; comfort working with Spark and large-scale data.
Deep fluency in experiment design and measurement
Strong product sense and executive communication, able to drive alignment in ambiguous, cross-functional environments.

Nice To Haves

Experience evaluating LLM/AI systems in production ( such as quality signals, human eval, safety/abuse considerations)
Familiarity with causal inference methods beyond AB tests

Responsibilities

Own measurable outcomes for the UGC ecosystem across Scribd and Slideshare; define success criteria and ensure we can prove durable impact on user experience and business results (with and without Ads).
Build and own the measurement and experimentation standard for UGC (north stars, guardrails, leading indicators, and post-launch validation.) Partner with the Product Analyst on consistent reporting and shared definitions.
Lead end-to-end experiment design and readouts for complicated UGC initiatives; turn ambiguous questions into testable hypotheses, ensure adequate power/sensitivity, interpret results with rigor, and drive go/no-go recommendations.
Develop exploratory and diagnostics models (e.g., activation/retention drivers, segment opportunity sizing, targeting) to translate user behavior signals into differentiated product features and experiences, and partner with Engineering/MLE to productionize validated approaches when needed.
Define evaluation frameworks for AI-driven features/workspace , ensuring performance is assessed across different user segments and audiences (informed by clustering or personalization where appropriate), alongside offline/online alignment, human evaluation where needed, and safeguards against unintended harms
Support Ads measurement and optimization; partner with the PM to improve CTR while protecting subscription conversion via explicit guardrails and incrementality-aware measurement.
Shape segmentation and prioritization strategy (intent/verticals, content types, lifecycle states) and ensure it’s usable for product decisions.
Drive cross-functional alignment and executive ready decision memos. Make tradeoffs, risks, and monitoring plans explicit, and raise the bar on measurement quality across Product, UXR, and Engineering.
Mentor and raise the analytics bar by reviewing analyses, setting best practices, and building a culture of rigorous, business-grounded measurement.
