Description
We are looking for a Principal Engineer to serve as a technical force multiplier for our Engineering Acceleration organization. As Principal Engineer for Agentic Engineering, you will architect and ship the foundational platform and capabilities that enables AI agents to operate as integrated participants in Pinterest's software development lifecycle.
Your responsibilities will include defining and driving Pinterest's technical strategy for agentic engineering, architecting and shipping production systems, reimagining Pinterest's SDLC, owning developer velocity measurement, serving as technical force multiplier across Platform, Infrastructure, and Engineering Acceleration, and driving engineering-wide adoption.
To be successful in this role, you will need 12+ years of software engineering experience with deep expertise in building developer platforms, internal tooling, or engineering infrastructure that measurably changed how engineers work at scale. You will also need demonstrated hands-on experience designing and shipping agentic AI systems in production, experience working in large-scale monorepos or complex multi-service codebases, and familiarity with agentic development best practices.
As a key technical advisor and delegation point, you will work with the Sr. Director, Engineering Acceleration, VP, Infrastructure, and Chief Architect to shape investment priorities and multi-year technical direction. You will also serve as a trusted partner and primary delegation point for the hardest technical questions facing this organization.
This is a startup-within-a-company opportunity, with a charter that is ambitious, problems that are largely unsolved, and systems that you will build will define how an entire engineering organization operates for years.
