The World We're Building 

Imagine the first day of college. The first week of a new job. The moment someone decides to stay or go. 

We build the digital experiences that shape those moments. Our platforms power orientation and onboarding for 400+ institutions including Harvard, UCLA, and Florida State University. We welcome over 4.5 million people per year into important life transitions. We are the market leader in interactive, video-driven onboarding. What we build moves people.   

Team and Mission 

You will lead a skilled development team inside a 50-person company where your impact is immediate and visible. Reporting to the Director of Technology, you will set technical direction, establish standards, mentor engineers, and remain hands-on with production code. 

The platforms you build and lead touch hundreds of thousands of students and employees every year. Strong technical leadership here has a direct, measurable impact on client outcomes and organizational growth.   

How We Work 

We are a goal-driven organization. Priorities are clear, commitments are tracked, and accountability is real and mutual. 

We hold a high technical bar and invest in the people who meet it. No politics. No unnecessary complexity. Just excellent work, done right. 

We have been doing this successfully for over 26 years — not a startup, not a corporate giant. A focused, talented team that takes quality seriously.
