Senior Software Engineer- Backend (Roleplays)

Seattle, WA

Who we are

Each of us at Yoodli has faced our own communication challenges — overcoming a lisp, freezing during a job interview, feeling anxious about speaking up. That shared empathy shapes a culture that's uplifting, inclusive, and deeply authentic. We value humility, a bias for action, and the belief that we win together.

Our team includes former employees from Google, Apple, Microsoft, Tableau, and beyond, united by a problem we've personally lived. We're headquartered in the heart of Seattle, and we're having a lot of fun along the way. Our culture is built on failing fast, iterating constantly, and taking bold bets.

We've raised $60M — including a $40M Series B led by WestBridge Capital — backed by Madrona, Neotribe, Cercano, and incubated at the Allen Institute for AI. We're valued at $300M and grew revenue 900% year-over-year.

Our customers include Google Cloud, Snowflake, Databricks, RingCentral, SAP, FranklinCovey, KornFerry, Sandler Training, Toastmasters, and many more — with learners in over 150 countries. Results speak for themselves: Google Cloud certified 15,000+ reps without scaling headcount. Snowflake recovered 1,200+ manager hours per quarter. Harness cut training review time by 75%.

We've been featured in TechCrunch, Axios, The Information, Forbes, Fast Company, and more.

As part of the Roleplays team, you'll be working on the engine that powers the heart of Yoodli. You'll be creating an AI-native experience of learning, pushing the bounds of models and real-time systems. You'll work throughout the frontend and backend stacks to build enterprise-grade software that works for company wide rollouts without a hitch. You'll go deep on technical challenges while being front and center to our user experience - building the technology that allows for a whole new paradigm of learning
