As a Principal Engineer within Servicing Digital, you'll help define and deliver Rocket's next generation of client-facing servicing experiences for millions of homeowners. Servicing Digital owns the end-to-end digital journey for clients after close — powering 's Rocket Mortgage Servicing platform and every interaction a client has with their loan, their account, and their servicer. We are entering a pivotal chapter — a full-scale System of Record modernization that will reshape the technical foundation beneath our client experiences and redefine how servicing works through AI-driven workflows and decisioning. The engineers who join us now will not inherit a finished system. They will build the one that replaces it. The Graph & API domain sits at the center of that transformation. You'll architect and govern the abstraction layer that keeps our client-facing products stable and decoupled as the systems beneath them change. Your work will determine how fast the vertical can move, how safely teams can ship, and how confidently Rocket can execute one of its most consequential technology investments.
Principal Engineers provide cross-organizational technical leadership, operating across multiple divisions and domains to drive enterprise-wide technology standards, build advanced platforms, and accelerate internal transformation. As key thought leaders, Principal Engineers define and influence technical strategy, shape engineering culture, and represent engineering in executive-level discussions. They introduce and scale innovative solutions — including AI and automation throughout the software development lifecycle — that materially impact the company and industry. In the Graph & API role, this mandate is sharpened by urgency: a full-scale System of Record migration makes stable, well-governed API abstractions a business-critical dependency. You will own the technical strategy for how Servicing Digital's graph and API layer is designed, governed, and evolved — ensuring that client experiences remain fast, coherent, and decoupled from the migration happening beneath them.
