We're looking for a passionate, self-motivated Senior Full-Stack Engineer to help us develop within our Axe Monitor product and component libraries.

We're AI-first and we mean it. You'll use AI to write and review code, including other people's, and you'll help build the context and practices that make AI effective on this codebase. AI raises how much code you can produce, which raises the value of being able to tell when it's wrong. Our team is fully remote and has flexible working hours.
