Lisp Software Engineer Jobs (NOW HIRING)

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 a Principal Backend Engineer on the Admin Workflows team, you'll own the systems that turn an admin's ideas and raw materials into engaging, AI-first training in minutes. Your job is to make that magic more powerful and more reliable at enterprise scale: building the content integrations that ingest source material from the systems customers already use, the agent framework that powers those roleplays, and the content creation workflows at the heart of our admin experience. You'll also help tell the story of the impact of Yoodli through AI-powered analysis and analytics - feedback and skills intelligence integrated deeply enough that customers can measure real improvement of their learners, not just activity.
