Principal Software Engineer - ATS Experience

Objective

The Principal Software Engineer on this Experience team drives the visual modernization of an established application with a Vue front end backed by PHP, where newer pages are built in Vue and legacy pages remain in jQuery. This is a hands-on senior development role focused on refreshing and elevating the user interface of a live product: modern, responsive, and accessible interfaces delivered within the application’s existing technology stack. This is a visual modernization effort, not a ground-up rewrite. You will improve the experience of a running application where it lives, which means you pair strong, transferable front-end engineering fundamentals with real depth in the application’s stack. A significant part of the work is modernizing legacy jQuery pages into modern, component-based Vue.

This role requires strong architecture thinking, but the day-to-day is hands-on coding, not high-level design from a distance. The expectation is that you design solutions and then implement them yourself. Our modernization strategy is built on hiring fewer, highly senior engineers who use AI-assisted development as a force multiplier, and we expect you to leverage agentic coding, spec-driven development, and AI-augmented code review as a core part of how you work, including to ramp quickly on an unfamiliar codebase. You will partner closely with product management and UX to translate experience goals into performant, consistent, and maintainable interfaces.
