We care deeply

We're looking for a passionate, self-motivated Senior Full-Stack Engineer to 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. 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.

• Critical AI Engineering: Leverage AI tools to accelerate delivery while strictly reviewing AI-generated code for security, logic, and accuracy.
• Backend Depth: 4+ years of full-stack engineering experience, with strong backend depth in Java, Spring Boot, Hibernate, and relational databases.
• Frontend Skills: 2+ years of experience with TypeScript, Node.js, and ReactJS.
• Skeptical AI Mastery: Proven experience using AI tools effectively alongside the critical judgment to catch AI errors and edge cases.
• Production Troubleshooting: Demonstrated ability to query databases, trace code, and resolve live production issues independently.
• Experience building complex software in large enterprise environments (finance, insurance, big tech, or scaled SaaS).
• Public Code: Active GitHub profile with inspectable code (Java samples preferred).
• Basic web accessibility knowledge. (Foundational familiarity with web accessibility principles (WCAG, accessible DOM patterns, ARIA) and a commitment to building domain expertise alongside industry leaders.
• Claude Certified Developer - Foundations (CCDV-F) credential (or equivalent practical experience).
