Job description

We’re looking for a passionate, self-motivated Senior Full-Stack Engineerto help us develop within our Axe Monitor product and component libraries. Front end work is done primarily in TypeScript and ReactJS. Backend work is a combination of Node.js and Java. This position will be expected to contribute to all aspects of the high volume, industry leading scanning solution.

This role serves as our primary engineering anchor during US Eastern business hours. You will drive backend architecture (Java / Spring Boot / SQL) and independently investigate and resolve production customer issues when overseas team members are offline. On the frontend, you’ll work with TypeScript, Node.js, and ReactJS.

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. What we’re hiring for is the judgment on top of that: AI raises how much code you can produce, which raises the value of being able to tell when it’s wrong. Axe Monitor is a large, long-lived system, and getting good output from an agent here takes someone who understands it.

Our team is fully remote and has flexible working hours.
