Principal Software Engineer

Role Description

The Principal Software Engineer is a force-multiplier and technical leader who drives innovation, establishes best practices, and solves complex problems across Fullbay's SaaS platform helping independent mechanics manage their businesses. You'll combine exceptional technical depth with the breadth of experience needed to tackle any challenge—from architecting scalable distributed systems to mentoring engineers and influencing organizational strategy. This role requires someone who can quickly prototype solutions, deliver proof-of-concepts with new technologies, and turn big ideas into reality while maintaining production excellence.

You'll work as part of the Principal Engineers team—a unified group that coordinates cross-domain architectural decisions, establishes technical standards, and provides strategic guidance across the organization. While you'll be assigned to specific domain teams, your primary responsibility is organizational impact, not embedding in day-to-day execution.
