## Description

As Principal Engineer, Core Product, you'll be the senior technical leader across Homebase's most critical product domains: Payroll, Scheduling, Time Tracking, HR Management (HRM). You'll contribute to Homebase business goals by thinking 18+ months in the future to deliver technical capabilities that support a resilient, maintainable, scalable, and trustworthy product.

This is a role for someone who thinks in systems, ships with urgency, and elevates everyone around them. You'll work at the intersection of deep technical craft and business impact - partnering closely with product, data, design, and engineering leadership to shape what Homebase builds and how we build it.

These are the key ways you'll contribute and create impact in this role:

 * Technical Leadership: In collaboration with our Technical Leadership group of Staff and Principal Engineers, drive Homebase's technical vision and architecture across our Core Product domains such as Payroll, Scheduling, Time Tracking, and HRM - creating coherence across domains that today serve 100K+ SMBs
 * API Strategy: Champion and help deliver Homebase's API strategy - building a platform that enables internal velocity, external integrations, and future partnership opportunities
 * Service Architecture: Lead the decomposition of core product systems into well-bounded services using domain-driven design and SOA principles
 * Technical Problem Solving: Identify and resolve cross-cutting technical challenges - data consistency, performance bottlenecks, reliability gaps - before they become customer problems
 * Engineering Excellence: Support and champion the Engineering culture to scale Engineering Excellence in all teams. Drive standards and patterns that are adopted because they're good, not because they're mandated; mentor senior and staff engineers to raise the overall bar
 * Cross-Functional Partnership: Partner with Product, Data, Design and Engineering leadership to shape roadmaps and ensure technical strategy aligns with business priorities
 * AI-First Engineering: Experiment with and deploy/build harness capabilities to accelerate engineering workflows - from code generation to test automation - and coach teams on doing the same. Aligned with our belief that the best use of AI accelerates quality of the codebase and quality products as well as delivery velocity.
